-- John Fouhy
Hello, and welcome to the aptitude user's manual! This introductory
section explains what aptitude is and how to get your hands on it; for
information on actually using it, please proceed to Chapter 1, Getting
started.
What is this aptitude thing, anyway?
aptitude is a featureful package manager for Debian GNU/Linux systems,
based on the renowned apt package management infrastructure. aptitude
provides the functionality of dselect and apt-get, as well as many
additional features not found in either program.
What is a package manager?
A package manager keeps track of what software is installed on your
computer, and allows you to easily install new software, upgrade software
to newer versions, or remove software that you previously installed. As
the name suggests, package managers deal with packages: collections of
files that are bundled together and can be installed and removed as a
group.
Often, a package is just a particular program. For instance, the instant
messaging client gaim is contained in the Debian package of the same name.
On the other hand, it is common for programs to consist of several
interrelated packages. For instance, the gimp image editor consists not
only of the gimp package, but also of the gimp-data package; in addition,
several optional add-on packages (containing esoteric data, documentation,
and so on) are also available. It is also possible for several small,
related programs to be contained in a single package: for instance, the
fileutils package contains several common Unix commands, such as ls, cp,
etc.
Some packages require other packages in order to function. In Debian,
packages can depend upon, recommend, suggest, break, or conflict with
other packages.
* If a package A depends upon another package B, then B is required for
A to operate properly. For instance, the gimp package depends upon the
gimp-data package in order to ensure that the GIMP graphics editor can
access its critical data files.
* If a package A recommends another package B, then B provides important
additional functionality to A that will be desired in most
circumstances. For instance, the mozilla-browser package recommends
the mozilla-psm package, which adds support for secure data transfers
to the Mozilla Web browser. While mozilla-psm is not strictly required
for Mozilla to function, most users will want Mozilla to support the
secure transmission of confidential data (such as credit card
numbers).
* If a package A suggests another package B, then package B provides
functionality that may enhance A, but is not needed in most cases. For
instance, the kmail package suggests the gnupg package, which contains
encryption software that can be used by KMail.
* If a package A conflicts with another package B, then the two packages
cannot be installed at the same time. For instance, fb-music-hi
conflicts with fb-music-low because they provide alternate sets of
music for the game Frozen Bubble.
The job of a package manager is to present an interface which assists the
user in managing the collection of packages installed on his or her
system. aptitude provides such an interface by building on the apt package
management system.
What is the apt system?
Being able to install and remove packages is great, but the basic software
for doing this (known as dpkg) does exactly that and nothing more. This is
fine if you download one or two packages by hand, but quickly becomes
cumbersome when you are trying to manage a large number of packages.
Furthermore, if your shiny new package requires software you haven't yet
installed, you have to download the newly required software by hand. And
if you later decide to remove the no-longer-shiny package, these extra
packages will linger on your system, consuming hard drive space, unless
you manually remove them.
Obviously, all of this manual labor is a tedious chore, and so most
package management systems come with software which takes care of some or
all of it for you. apt is a common base on which to build these programs:
in addition to aptitude, programs such as synaptic and apt-watch make use
of apt.
apt works by keeping a list of the packages that can be downloaded from
Debian on your computer. This list is used to find packages that need to
be upgraded and to install new packages. apt can also solve many
dependency problems automatically: for instance, when you choose to
install a package, it will find any additional required packages and
install those as well.
When working with a package manager based on apt, such as aptitude, you
will typically perform three basic tasks: you will update the list of
packages that are available by downloading new lists from the Debian
servers, you will select which packages should be installed, upgraded, or
removed, and finally, you will commit your selections by actually
performing the installations, removals, etc.
apt-based package managers read the list of "sources" -- repositories of
Debian packages -- from the file /etc/apt/sources.list. The format and
contents of this file are beyond the scope of this document, but are
described in the manual page sources.list(5).
How can I get aptitude?
In case you are reading this manual but aptitude is not yet installed on
your system, this section explains how to correct this unfortunate
situation. Most people should head straight for the section on binary
packages.
Pre-built aptitude packages, or, "what 99% of users should do"
Pre-built, or "binary" packages are the easiest and most common way to
install aptitude. You should only attempt a source install if binary
packages are not available for some reason, or if you have unusual needs
that are not met by binary packages.
If you are using a Debian system, execute the following command as root:
apt-get install aptitude. If you are not using a Debian system, your
system provider might have created a pre-built package of aptitude; if you
are not sure, you can contact them for further suggestions.
Building aptitude from source code
You also can build aptitude from source; however, this is probably not a
useful exercise unless apt is already available on your system. If it is,
you can install aptitude from source with the following steps:
1. Install the following pieces of software:
* A C++ compiler, such as g++.
* The development files for apt, typically available in a package
with a name like libapt-pkg-dev.
* The libsigc++-2.0 library, available in the package
libsigc++-2.0-dev or from http://libsigc.sourceforge.net.
* The cwidget library, available in the package libcwidget-dev or
from http://cwidget.alioth.debian.org.
* The gettext program, which should be included with your Linux
distribution.
* A make tool, such as GNU make.
2. Last but not least, download the most recent aptitude source code,
available from http://packages.debian.org/unstable/admin/aptitude.
(scroll to the bottom of the page and download the ".orig.tar.gz"
file)
Once all the required components are available, open a terminal and
execute the command tar zxf aptitude-0.6.11.tar.gz to unpack the source
code. Once the source code is unpacked, type cd aptitude-0.6.11 &&
./configure && make to compile aptitude. If this succeeds, make sure you
are the root user (by using su, for instance), then type make install to
install aptitude on your computer. Once aptitude is successfully
installed, typing aptitude at a command prompt should start the program.
Tracking and participating in aptitude development
Getting the aptitude development source tree
If you want to test the latest bleeding-edge source code for aptitude, you
can download unreleased aptitude source code using Git. Install Git
(available from http://git-scm.com/) and execute the command git clone
git://anonscm.debian.org/aptitude/aptitude.git to retrieve the most recent
source code.
[Warning] Warning
The aptitude Git repository is an active development tree; it
will change as bugs are fixed and features are added, and there
is absolutely no guarantee that it will even compile, let alone
run properly! Bug reports are welcome, but be aware that you use
development code entirely at your own risk!^[1]
Mailing list
The primary mailing list for aptitude development is
<aptitude-devel@lists.alioth.debian.org>. Archives of the list are located
at http://lists.alioth.debian.org/pipermail/aptitude-devel/. To subscribe,
visit the Web page
http://lists.alioth.debian.org/mailman/listinfo/aptitude-devel.
Submitting patches
Ideally, patches should be submitted to the aptitude mailing list,
<aptitude-devel@lists.alioth.debian.org>. But if you prefer sending them
by private email, you may email them to <aptitude@packages.debian.org> or
<dburrows@debian.org>. A brief description of the motivation behind your
patch, and an explanation of how it works, are greatly appreciated.
Tracking changes to the aptitude source tree
The aptitude source tree is regularly updated with new features, bugfixes,
and new bugs. Once the source code is available on your computer (see the
previous section), you can cd into it and type git pull to update it with
any changes made to the main repository.
To automatically receive notifications when changes are made to the
aptitude codebase, subscribe to the Atom feed available at
http://anonscm.debian.org/gitweb/?p=aptitude/aptitude.git;a=atom or RSS
feed available at
http://anonscm.debian.org/gitweb/?p=aptitude/aptitude.git;a=rss.
Building aptitude from the development tree
To build aptitude from the Git repository, you must have the programs
autoconf and automake installed. Type sh ./autogen.sh && ./configure to
generate the files needed to compile aptitude, then execute make and make
install.
--------------------------------------------------------------------------
^[1] Of course, all free software is used at your own risk, but the risk
involved in using an active development tree is much higher.

aptitude is a sizeable program with many features, and it can be a bit
overwhelming for new users to get acquainted with it. This chapter does
not exhaustively describe the features of aptitude (see Chapter 2,
aptitude reference guide for that), but it does provide a walk-through of
the basic and most commonly used features of the program.
Using aptitude
This section describes how to use the visual interface of aptitude. For
information on using aptitude's command-line interface, see the section
called "Using aptitude from the command line".
aptitude basics
To run aptitude, open your favorite text terminal, and at the command
line, type:
foobar$ aptitude
Once the cache is loaded (this may take some time on slower machines), the
main aptitude screen should appear:

These packages are currently installed on your computer.
As you can see, the main screen of aptitude is divided into several
regions. The blue line at the top of the terminal is the menu bar, and the
blue lines below it are informational messages describing some important
commands. The black space that follows is the list of all available
packages, in which some groups of packages are listed. The currently
selected group ("Installed Packages") is highlighted, and its description
is shown in the lower black space.
As the top line of the screen suggests, you can access aptitude's menus by
pressing Control+t; you can also click the mouse on a menu title if your
system supports it. Pressing Control+t will open the Actions menu:

Perform all pending installs and removals
Use the arrow keys and Enter to select menu items (or, if your system
supports it, click on them with a mouse); to close the menu without
selecting anything, press Control+t again. The currently highlighted menu
item is explained at the bottom of the screen. If a menu item can be
activated using a keyboard shortcut, the shortcut is displayed in the
menu: for instance, the command "Update package list" can be activated by
pressing u.
At any time, you can press ? to display an on-line reference to the
available keyboard shortcuts.
Navigating the aptitude package list
The list of packages is the primary interface to aptitude. When aptitude
starts, the list is organized into a number of groups, as can be seen in
the following screen shot:

[Note] Note
Empty groups of packages are automatically hidden by aptitude, so
you may see more or less groups than appear in this screen shot.
In the screen shot above, the first group ("Installed Packages") is
highlighted to indicate that it is currently selected. You can move the
selection up and down with the arrow keys; note that the description below
the package list changes as you do so. To "expand" a group, press Enter
while the group is selected:

These packages are currently installed on your computer.
As you can see, the "Installed Packages" group has been expanded to reveal
its contents: it contains a number of subgroups, loosely defined by what
types of software they contain. Expanding the "admin" section by selecting
it and pressing Enter, we see:

Packages in the 'admin' section allow you to perform administrative tasks such
as installing software, managing users, configuring and monitoring your system,
examining network traffic, and so on.
The "admin" group contains a single subgroup, the "main" Debian archive.
Expanding this group reveals some packages!
[Tip] Tip
To save time, you can use the [ key to expand all the subgroups of a
group at once. Selecting "Installed Packages" and pressing [ would
have immediately revealed the packages in the screenshot below.

In addition to the arrow keys, you can move the selection through the
package list by a page of information at a time using the Page Up and Page
Down keys.

When there is more information in the lower half of the display than
fits into the available space, the a and z keys can be used to
scroll through it.

Managing packages
Now that you can move about the list of packages, it's time to start using
aptitude to install and remove packages. In this section you will learn
how to flag packages for installation, deletion, and upgrade.
[Tip] Tip
You can only change your system's setup as the root user. If you
want to experiment with aptitude, you can safely run it as any user
other than root without damaging your system in any way. aptitude
will tell you when you try to do something that only root can do,
and if you want to continue, you must type root's password.
All changes to a package are performed by first highlighting it in the
package list, then pressing a key corresponding to the action which should
be performed. The basic action keys ^[2] are + to install or upgrade a
package, - to remove a package, and = to prevent a package from being
automatically upgraded (this is known as holding the package). These
actions are not performed immediately; aptitude will simply update the
package list to show the change that has been requested.
For instance, in the screen shot below, the kaffeine-mozilla package was
selected and + was pushed. The package is now highlighted in green and the
letter "i" has appeared to the left of its name, to indicate that it will
be installed; in addition, an estimate of the amount of space that the
package will use is displayed.

[Tip] Tip
At any time, you can use Undo -> Undo (Control+u) to "undo" any
change to one or more packages. This is very useful if an action has
unforeseen consequences and you want to "take it back".
In addition to actions that affect individual packages, another important
action is available: typing U will attempt to upgrade any packages that
can be upgraded. You should use this command on a regular basis to keep
your system up-to-date.
Managing broken packages
Sometimes, changing a package's state will cause dependency relationships
to become unfulfilled; packages with unfulfilled dependencies are said to
be broken. aptitude will warn you when this happens, and explain why it
occured. For instance, here is what happens if I attempt to remove
sound-juicer:

wrong: first, the number of broken packages is displayed in the upper blue
area; second, the lower half of the display changes to describe broken
packages that are related to the currently highlighted package; third, a
bar appears at the bottom of the screen with a suggestion on how to solve
the problem. To quickly find broken packages in the package list, you can
press b or search for ?broken.
[Note] Note
The text [1(1)/...] indicates the progress of aptitude's dependency
resolver. The first number is the solution that you have currently
selected, and the second one is the number of solutions that
aptitude has already generated. The presence of the text "..."
indicates that there may be additional solutions beyond the ones
generated; if aptitude knew for certain that it had generated the
only possible solution, this indicator would read [1/1].
To see more information about how aptitude thinks you can solve this
problem, press e. A screen similar to the following will appear:

tell aptitude that it should not cancel the removal of sound-juicer in
this way.

As you can see, the list item corresponding to keeping sound-juicer at its
current version has turned red and been marked with an "R", indicating
that it has been rejected. Solutions that you generate in the future (that
is, any solution that you have not yet viewed) will not include this
action, although solutions that were already generated and contain this
action will be available.
[Note] Note
In the above screen image, a description of sound-juicer is
displayed in the middle of the screen; below it, you can see the
dependency that caused sound-juicer to be kept at its current
version, along with all the ways to resolve this dependency that
aptitude knows about.
For instance, if this rejection is imposed immediately after attempting to
remove sound-juicer, pressing . retrieves the following solution, skipping
the solution that cancels the installation of sound-juicer and downgrades
gstreamer0.8-cdparanoia.

Rejections are only applied to newly generated solutions: that is,
solutions that are generated when you press . while viewing the last

rejections. You can cancel a rejection at any time by once again selecting
the rejected action and pressing r; this will permit solutions containing
the action to be generated again, including any solutions that were
previously "skipped".
The opposite of rejecting an action is approving it. To approve an action,
just select it and press a; this forces the problem resolver to choose the
action whenever possible^[3]. Approved actions will turn green and will be
marked with "A", as in the following screenshot:

[Important] Important
If you do not resolve any broken dependencies, aptitude will
automatically implement its current suggestion when you commit
your selections by pressing g. However, it is hard to
automatically solve dependency problems, and you may not be
happy with the results, so it is generally better to look at
what aptitude plans to do before committing your selections.
Updating the package list and installing packages
At this point, you know enough about aptitude to actually make
modifications to your system.
You should periodically update your list of available packages from the
Debian servers, to keep track of new packages and new versions of
packages. To do this, press u. At any time during the download, you can
press q to abort it.
Once you have fresh lists of packages, you can choose the packages to
upgrade, install, or remove as described in the previous section. To
review the actions you have requested, press g once. When installing the
kaffeine-mozilla package (from the previous example), the following screen
appears:
Actions Undo Package Search Options Views Help
f10: Menu ?: Help q: Quit u: Update g: Download/Install/Remove Pkgs
aptitude 0.2.14.1 Will use 2925kB of disk space DL Size: 1375kB
--\ Packages being automatically installed to satisfy dependencies
piA kaffeine +2843kB <none> 0.4.3-1
--\ Packages to be installed
pi kaffeine-mozilla +81.9kB <none> 0.4.3-1
These packages are being installed because they are required by another package
you have chosen for installation.
If you select a package, an explanation of its current state will appear in this
space.
As you can see, aptitude automatically decided to install kaffeine for me
because kaffeine-mozilla requires it. At this point, I have the choice of
either continuing with the installation by pressing g, or aborting it by
pressing q.
Using aptitude from the command line
In addition to its "visual" interface described in the previous section,
aptitude can be used to manage packages directly from the command-line in
the same way that you would use apt-get. This section covers the most
common aptitude command-line actions; for more information, see the
aptitude command-line reference.
In general, a command-line invocation of aptitude will look like this:
aptitude action [arguments...]
action tells aptitude what action it is to take; the remaining arguments
are used in an option-specific fashion. Typically they will consist of
package names and command-line switches^[4].
The most important actions are:
aptitude update
This command updates the package lists, as if you had entered the
visual interface and pressed u.
aptitude safe-upgrade
This command will upgrade as many packages as it can upgrade
without removing existing packages.
It is sometimes necessary to remove one package in order to
upgrade another; this command is not able to upgrade packages in
such situations. Use the full-upgrade command to upgrade those
packages as well.
aptitude full-upgrade
Like safe-upgrade, this command will attempt to upgrade packages,
but it is more aggressive about solving dependency problems: it
will install and remove packages until all dependencies are
satisfied. Because of the nature of this command, it is possible
that it will do undesirable things, and so you should be careful
when using it.
[Note] Note
For historical reasons, this command was originally named
dist-upgrade, and that name is still recognized by
aptitude.
aptitude [ install | remove | purge ] pkg1 [pkg2...]
These commands install, remove, or purge^[5] the specified
packages. "Installing" a package which is already installed but
can be upgraded will cause it to be upgraded.
aptitude search pattern1 [pattern2...]
This command searches for packages whose name contains any of the
given patterns, printing the result to the terminal. In addition
to just being a string of text, each pattern can be a search
pattern as described in the section called "Search patterns". ^[6]
For instance, "aptitude search gnome kde" will list all packages
whose name contains either "gnome" or "kde".
aptitude show pkg1 [pkg2...]
Prints information about each pkg to the terminal.
The commands that install, upgrade, and remove packages all accept the
parameter -s, which stands for "simulate". When -s is passed on the
command line, the program performs all the actions it would normally
perform, but does not actually download or install/remove any files.
aptitude will sometimes present a prompt like this:
The following NEW packages will be automatically installed:
space-orbit-common
The following NEW packages will be installed:
space-orbit space-orbit-common
0 packages upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Need to get 3200kB of archives. After unpacking 8413kB will be used.
Do you want to continue? [Y/n/?]
In addition to the obvious options of "Yes" and "No", a number of commands
are available which can be used to change the information displayed at the
prompt, or to specify further actions. For instance, typing s will display
or hide information about how much space each package will use:
Do you want to continue? [Y/n/?] s
Size changes will be shown.
The following NEW packages will be automatically installed:
space-orbit-common <+8020kB>
The following NEW packages will be installed:
space-orbit <+393kB> space-orbit-common <+8020kB>
0 packages upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Need to get 3200kB of archives. After unpacking 8413kB will be used.
Do you want to continue? [Y/n/?]
Similarly, typing d will display information about automatically installed
or removed packages:
The following NEW packages will be automatically installed:
space-orbit-common (D: space-orbit)
The following NEW packages will be installed:
space-orbit space-orbit-common
0 packages upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Need to get 3200kB of archives. After unpacking 8413kB will be used.
This shows that space-orbit-common is being installed because space-orbit
depends on it. You can see the entire list of possible entries by entering
? at the prompt.
If your request violates dependencies in a way that cannot be trivially
resolved, aptitude will ask you what to do:
The following packages are BROKEN:
libsdl1.2debian
The following packages will be REMOVED:
libsdl1.2debian-alsa
.
.
.
The following actions will resolve these dependencies:
Install the following packages:
libsdl1.2debian-all [1.2.12-1 (unstable)]
Score is 41
Accept this solution? [Y/n/q/?]
Typing y (or simply pressing enter) will accept the proposed solution.
Typing n will display the "next best" solution:
Accept this solution? [Y/n/q/?] n
The following actions will resolve these dependencies:
Install the following packages:
libsdl1.2debian-esd [1.2.12-1 (unstable)]
Score is 19
Accept this solution? [Y/n/q/?]
As with the main command-line prompt, you can perform a number of
additional actions, including manually altering the states of packages,
from the dependency resolution prompt. Type ? to see a complete list.
Typing q will abort the automatic resolver and allow you to resolve the
dependencies manually:
Accept this solution? [Y/n/q/?] q
aptitude failed to find a solution to these dependencies. You can solve them yourself by hand or type 'n' to quit.
The following packages have unmet dependencies:
libsdl1.2debian: Depends: libsdl1.2debian-alsa (= 1.2.12-1) but it is not installable or
libsdl1.2debian-all (= 1.2.12-1) but it is not installable or
libsdl1.2debian-esd (= 1.2.12-1) but it is not installable or
libsdl1.2debian-arts (= 1.2.12-1) but it is not installable or
libsdl1.2debian-oss (= 1.2.12-1) but it is not installable or
libsdl1.2debian-nas (= 1.2.12-1) but it is not installable or
libsdl1.2debian-pulseaudio (= 1.2.12-1) but it is not installable
Resolve these dependencies by hand? [N/+/-/_/:/?]
You can use any of the package manipulation commands to resolve the broken
dependencies (type ? for a full list of the available commands). Type n or
press enter to quit aptitude:
Resolve these dependencies by hand? [N/+/-/_/:/?] n
Abort.
For complete documentation of the command-line features of aptitude, see
Command-line reference.
--------------------------------------------------------------------------
^[2] You can also change packages using the Package menu; see the section
called "The Package menu" for details.
^[3] Approving an action is slightly different from requiring all
solutions to contain the action; what it means is that given a choice
between an approved action and a non-approved action, the resolver will
always pick the approved action. If there are several possible approved
actions, all of them will be candidates to be placed into the solution.
^[4] A "switch" is a letter preceded by a hyphen: for instance, "-a",
"-v", etc.
^[5] Purging a package removes the package, as well as all its
configuration files.
^[6] In fact, the same is true of the commands that take packages as
arguments, such as install or show.

-- Lewis Carrol, Alice in Wonderland
aptitude is a large program with many features, and it is sometimes
difficult to remember how to do something, or even to remember whether
that something is even possible. Indeed, many feature requests received by
the author describe features which are already present but are difficult
to find.^[7]
In an attempt to combat this obscurity, this reference guide describes
every feature and configuration parameter of aptitude. For a more gentle
guide to the important features of aptitude, see Chapter 1, Getting
started.
[Note] Note
aptitude's behavior and appearance can be configured in a number of
ways. This manual describes how the program works with the default
settings; descriptions of how various settings affect behavior are
given in the section called "Customizing aptitude".
The aptitude terminal user interface
This section describes the parts of the terminal-based user interface of
aptitude that do not deal with managing packages.
Using the menus
The menu bar at the top of the screen lists the most important commands in
aptitude. To activate the menu bar, press Control+t; you can then navigate
it using the arrow keys and select a menu item using Enter.
Some menu items also have "hotkeys": letters or numbers that can be used
to select the item while the menu is active. These hotkeys are displayed
in a brighter shade of white than the rest of the menu.
In addition, some menu items have "shortcuts": keystrokes that perform the
same action as the menu item while the menu is not active. These
keystrokes are listed on the right-hand side of the menu.
In the remainder of the manual, menu commands will be written like this:
Menu -> Item (key). This indicates that you should choose Item from the
Menu menu, and that key is the shortcut for this command.

Working with multiple views
aptitude allows you to work with several "views" at once. A "view"
(sometimes called a "screen") is simply something that can appear in the
area of the screen below the menu bar. The most common view is the package
list, but download views are also common.
When several views are open at once, a bar listing all the active views
will appear at the top of the screen. For instance, if I examine apt by
pressing Enter, then examine libc6, the screen will look something like
this:

If you select "Become root", aptitude will prompt you for root's password;
when you have correctly entered it, aptitude will perform the action that
required root privileges. You will still be root after the action
completes.
You can switch to the root account at any time using the command Actions

preserved (but will not be saved until you quit aptitude).
By default, aptitude will use the command su to gain root privileges. If
you would like it to use some other command (such as sudo), set the
configuration option Aptitude::Get-Root-Command.
Managing packages
This section describes how to manipulate the list of packages, how to
install new packages on your system, and how to remove old packages.
Managing the package list
To keep the list of packages up-to-date, it is recommended that you
periodically update it. You can do this using the Actions -> Update
package list (u) command.
Accessing package information
Information about packages is presented in several locations in aptitude:
the package list gives a quick overview of the state of each package, and
additional views providing detailed information about a package are also
available.
The package list
The package list displays an "at-a-glance" synopsis of a package's state.
For instance, the package webmin might have the following synopsis:
piAU webmin +5837kB <none> 1.160-2
The four characters on the left-hand side of the synopsis show that the
package is not installed ("p"), that it is going to be installed ("i"),
that it was automatically chosen to be installed ("A"), and that it is
untrusted ("U"). On the right-hand side of the synopsis, the current
version and the most recent available version are displayed, along with an
indication of how much space will be used by the upgrade.
[Tip] Tip
You can customize how package synopses are displayed; see the
section called "Customizing how packages are displayed" for details.
The four status flags on the left-hand side of the screen give the basic
information about a package's state. The first character is the package's
current state. The second character is the action which will be taken on
the package. The third character indicates whether the package was
automatically installed (see the section called "Managing automatically
installed packages"), and the fourth character indicates whether the
package is trusted (see the section called "Understanding and managing
package trust").
The possible values of the "current state" flag are given in Figure 2.9,
"Values of the "current state" flag" and the possible values of the
"action" flag are given in Figure 2.10, "Values of the "action" flag".
Figure 2.9. Values of the "current state" flag
i - the package is installed and all its dependencies are satisfied.
c - the package was removed, but its configuration files are still
present.
p - the package and all its configuration files were removed, or the
package was never installed.
v - the package is virtual.
B - the package has broken dependencies.
u - the package has been unpacked but not configured.
C - half-configured: the package's configuration was interrupted.
H - half-installed: the package's installation was interrupted.
Figure 2.10. Values of the "action" flag
i - the package will be installed.
u - the package will be upgraded.
d - the package will be deleted: it will be removed, but its configuration
files will remain on the system.
p - the package will be purged: it and its configuration files will be
removed.
the package will be held back: it will be kept at its current version,
h - even if a newer version becomes available, until the hold is
cancelled.
F - An upgrade of the package has been forbidden.
r - the package will be reinstalled.
the package is "broken": some of its dependencies will not be
B - satisfied. aptitude will not allow you to install, remove, or upgrade
anything while you have broken packages.
In addition, aptitude will use colors to indicate package state if your
terminal supports it. State distinctions are mainly displayed using the
background color:
Black
The package cannot be upgraded (or is not going to be installed),
and it has no dependency problems. If the package is installed,
its name will be highlighted.
Green
The package is going to be installed.
Blue
The package is currently installed, and it will be upgraded.
Magenta
The package is currently installed, but it will be removed.
White
The package is currently installed, and it is "held" at its
current version: automatic upgrades will ignore it.
Red
This package is broken: some of its dependencies will not be
satisfied.
Finally, the lower half of the screen displays the long description.
aptitude will attempt to detect whether the package is involved in a
dependency problem; if so, information regarding the dependency problem
will be displayed here. To cycle between dependency information and the
package description, press i.

This display can be navigated in a manner similar to the package list: for
instance, in the screenshot above, I expanded the dependency on apt-doc,
revealing the available versions of apt-doc which will fulfill the
dependency. These versions can be manipulated in the same way that
packages can: for instance, to install version 0.5.25 of apt-doc, you
would highlight it and press +.
[Tip] Tip
To quickly satisfy a dependency, select the dependency and press +;
aptitude will attempt to automatically satisfy it.
In addition to the dependencies of a package, you can view the package
names that it Provides, the packages which depend upon it, and the
available versions of the package (including any other packages that
Provide it).
As usual, you can dismiss this screen and return to the main view by
pressing q. For convenience, a few other information screens (which only
display some commonly-used information, hiding the rest) are available:
press v to view the versions of a package, d to view the dependencies of a
package, and r to view the "reverse dependencies" of a package (packages
which depend upon it).
Modifying package states
The following commands are available to modify the states of packages.
Commands take effect the next time you perform an install run; until you
do, all of these commands can be reversed using Undo -> Undo (Control+u).
To apply a command to a package, simply select the package in a package
list and issue the command. These commands can also be applied to groups
of packages by selecting the group header (for instance, "Upgradable
Packages") and issuing the command.

| | Flag the current package for installation. |
| | |
| Install: Package -> | If the package is not installed, it will be |

| Purge: Package -> Purge | If the package is installed, it will be |
| (_) | removed. Furthermore, even if it is removed, |
| | any remaining files (such as configuration |
| | files) related to the package will be |
| | removed from the system. |
|-------------------------+----------------------------------------------|
| | Flag the current package to be kept at its |
| | current version. |
| Keep: Package -> Keep | |
| (:) | Any action that was to be performed on the |
| | package -- installation, removal, or upgrade |
| | -- is cancelled, and any persistent hold |
| | that was set on the package is removed. |

| | Set a persistent hold on the package. |
| | |
| | As with Keep, any action that was to be |
| Hold: Package -> Hold | performed on the package is cancelled. In |
| (=) | addition, the package will not be |
| | automatically upgraded ^[a] until the hold |
| | is removed. You may cancel a hold by issuing |
| | the Install command. |
|-------------------------+----------------------------------------------|
| | The package will not be automatically |
| | upgraded^[a] to the version it would |
| | currently be upgraded to. If it was going to |
| | be upgraded, the upgrade will be cancelled. |
| | |
| | If you issue this command on a particular |
| Package -> Forbid | version of a package, the package will not |
| Version (F) | be upgraded to the selected version. Note |
| | that only one version can be forbidden at |
| | once. |
| | |
| | This functionality is largely provided as a |
| | convenience for users of the "unstable" |
| | distribution, so they can avoid known-bad |
| | versions of packages. |
|-------------------------+----------------------------------------------|
| | Flag the current package for reinstallation. |
| | |
| | Note that the reinstallation will not be |
| Reinstall: Package -> | saved when you quit aptitude or perform an |
| Reinstall (L) | install run, for technical reasons |
| | (essentially, the underlying software layers |
| | (dpkg and apt) do not provide any way to |
| | find out whether a reinstallation was |
| | successful or not). |
|-------------------------+----------------------------------------------|
| | Sets whether the package is treated as |
| Package -> Mark Auto | having been automatically installed; |
| (M), Package -> Mark | automatically installed packages will be |
| Manual (m) | removed when no other package requires them. |
| | For more information, see the section called |
| | "Managing automatically installed packages". |
|------------------------------------------------------------------------|
| ^[a] That is, it will be unaffected by Actions -> Mark Upgradable (U) |
| or the full-upgrade or safe-upgrade command-line actions. |
+------------------------------------------------------------------------+
In addition to these commands that affect the selected package, there are
two commands that affect large numbers of packages at once regardless of
what is selected. Actions -> Forget new packages (f) clears the "new"
status of all packages in the package list, and Actions -> Mark Upgradable
(U) flags every package which can be upgraded for upgrade, except for
packages that are held back or would be upgraded to a forbidden version.
[Note] Note
All changes to package states are saved when you quit aptitude,
update the package list, or perform an install run. If you do not
wish to save your changes, you can always abort aptitude by
pressing Ctrl-C.
Downloading, installing, and removing packages
Changing package states as described in the previous section does not
actually affect what is installed on your system. Thus, you can adjust the
state of packages without affecting your system until you are happy with
what you see; once you are, you can "commit" the changes by actually
installing and removing packages.^[8]
To commit your changes, use the Actions -> Install/remove packages (g)
command. Selecting this command will display a preview screen describing
the changes that will be performed. This screen is just a package list,
and you can manipulate the packages (for instance, cancelling unwanted
removals) in the same way that you could in the main list.
When you are done, use Views -> Close (q) to cancel the installation, or
use Actions -> Install/remove packages (g) to proceed. aptitude will
download any files that need to be downloaded, then prompt you to continue
with the installation. When you select "Continue", the installations and
removals will commence.
Packages that are downloaded by aptitude are placed in a cache directory
(typically /var/cache/apt/archives). Normally, they are just left in this
directory ad infinitum. To delete all the files in this directory, use
Actions -> Clean package cache; to delete only files which cannot be
downloaded again (ie, obsolete packages), use Actions -> Clean obsolete
files.
Understanding and managing package trust
apt's ability to access multiple package sources leads to a potential
security vulnerability. Suppose you add an archive of packages published
by Joe Random Hacker to your sources.list file in order to install Joe's
gargleblast package. It is possible, however, that -- unbeknownst to you
-- Joe's archive also contains his own "customized" versions of packages
such as libc6 and ssh...versions that steal your private information or
open backdoors on your system! If these packages have higher version
numbers than the legitimate Debian packages, apt will blithely install
them on your system during your next upgrade, allowing Joe to do his dirty
work undetected. Joe could also break into your mirror of the Debian
archives and replace the legitimate software with his doctored version.
Luckily, newer versions of apt and aptitude, such as the version
documented in this manual, have built-in safeguards to help defeat this
type of attack. apt uses strong security mechanisms based on the popular
GPG encryption software to verify that the packages being distributed from
the official Debian mirrors are the same packages that were uploaded by
the Debian developers. aptitude will then warn you if you attempt to
install a package from a non-Debian source, or if you attempt to upgrade a
package that was installed from a Debian source to a version that came
from a non-Debian source.
[Warning] Warning
The security mechanisms in apt provide a near-perfect guarantee
that the contents of your archive mirror are identical to the
contents of the master Debian archive. However, they are not a
panacea: for instance, there are many ways that a tampered
package could theoretically find its way into the master Debian
archive.
Ensuring that you only install software from a trusted source
will give you an important degree of protection against
malicious packages, but it cannot eliminate all the risks
inherent in installing software.
Understanding trust
apt allows the administrator of an archive to provide a signature of the
archive's index. This signature, which (for all practical purposes) cannot
be forged, indicates that the package files listed in the index are the
same files that the administrator intended to place in the archive: ie,
that the contents of the archive have not been tampered with since it was
created.^[9] The signature can be validated by checking that it
corresponds to the administrator's public key. The public key of the
Debian archive is distributed with apt, typically on your Debian CD.
When aptitude downloads an archive index, it will check whether the index
is properly signed. If it is unsigned, aptitude will not trust package
files from that archive. (see below for information on what this means) If
it has a signature but the signature is incorrect or cannot be verified, a
warning will be printed and aptitude will refuse to trust packages from
that archive.
Later, when you perform an install run, aptitude will check whether the
packages are from trusted sources. If an untrusted package is being
installed, or a package is being upgraded from a trusted to an untrusted
version, a warning will be displayed and you will have the opportunity to
abort the download:

Trusting additional keys
You might find it useful to allow apt to trust additional archives,
besides the main Debian archive. For each archive that you want to trust,
you will have to acquire the public key that is used to sign the archive's
package index. This is typically a text file whose name ends in .asc; it
might be provided by the site administrator or downloadable from a public
keyserver. For more information on what public keys are and how to get
them, see the GPG web page.
The list of keys that apt will trust is stored in the keyring file
/etc/apt/trusted.gpg. Once you have the GPG key, you can add it to this
file by executing the command gpg --no-default-keyring --keyring
/etc/apt/trusted.gpg --import newkey.asc. aptitude will then trust any
archive that is signed with the key contained in newkey.asc.
[Warning] Warning
Once an archive's key has been added to the APT keyring, it will
be trusted just as much as the main Debian mirrors themselves!
You should only do this if you are very confident that the key
you are adding is correct and that the person who holds the key
is trustworthy and competent.
Managing automatically installed packages
To install one package, it is often necessary to install several others
(to fulfill its dependencies). For instance, if you wish to install the
clanbomber package, you must also install the package libclanlib2. If you
remove clanbomber again, you probably no longer need the libclanlib2
package; aptitude will attempt to detect this and automatically remove the
libclanlib2 package.
It works like this: when you install a package, aptitude will
automatically install any other packages on which it depends. These
packages are marked as having been "automatically installed"; aptitude
will monitor them and remove them when they are no longer depended upon by
any manually installed package ^[10] . They will appear in the preview as
"packages being removed because they are no longer used."
As with any automatic process, there is a potential for things to go
haywire. For instance, even if a package was automatically installed to
start with, it might turn out to be useful in its own right. You can
cancel the "automatic" flag at any time by pressing m; if the package is
already being removed, you can use Package -> Install (+) to cancel the
removal and clear the "automatic" flag.
Resolving package dependencies
Dependency resolution in aptitude
There are two main dependency resolution algorithms in aptitude.
The first is an algorithm that is also used by programs such as apt-get
and synaptic; I will call it "immediate resolution". It is invoked
whenever you select a package for installation interactively, and
immediately after one or more packages are marked for installation at the
command-line. Immediate resolution is fast and will solve most dependency
problems, but it is sometimes unable to find any solution.
The second algorithm, which I will call "interactive resolution", is
invoked when packages have broken dependencies even after immediate
resolution^[11]. It can resolve more dependencies, it allows you to review
a solution before applying it, and it allows you to provide feedback to
the resolver, guiding it towards a better solution.
Immediate dependency resolution
Whenever you choose to install or upgrade a package in aptitude, aptitude
makes an immediate attempt to resolve any of its dependencies that are not
fulfilled. For each unsatisfied dependency (either a "Depends", a
"Recommends", or a "Conflicts"), it performs the following steps:
1. If the dependency is a recommendation, aptitude tries to guess whether
it is a "new" recommendation or a "previously satisfied"
recommendation. aptitude considers a recommendation to be "new" if the
package declaring the recommendation is not currently installed, or if
its installed version does not recommend a package of the same name.
On the other hand, a recommendation is "previously satisfied" if the
package declaring the recommendation is installed, the currently
installed version recommends a package of the same name, and that
recommendation is currently fulfilled.
For example: suppose that version 1.0 of prog recommends version 4.0
of libcool1, but version 2.0 of prog recommends version 5.0 of
libcool1, and also recommends apache. If you choose to upgrade prog
from version 1.0 to version 2.0, the recommendation of apache will be
considered to be "new" because version 1.0 of prog did not recommend
apache. On the other hand, the recommendation of libcool1 is not
"new", because version 1.0 of prog recommended libcool1, even though
it recommended a different version. However, if libcool1 is installed,
then that recommendation will be considered to be "previously
satisfied".
If the configuration option Apt::Install-Recommends is true, aptitude
will always attempt to fulfill "new" and "previously satisfied"
recommendations; all others will be ignored by immediate resolution.
If that option is false, immediate dependency resolution will ignore
all recommendations.
2. If the dependency is on several packages combined with OR, examine
each of the alternatives in the order that they are given. For
instance, if a package depends on "exim | mail-transport-agent",
aptitude will first process exim, then mail-transport-agent.
3. For each alternative, attempt to resolve it. If the dependency is a
conflict, remove the current alternative if it is installed (and for
an unversioned conflict, also remove any package providing the target
of the conflict). Otherwise, install the candidate version of the
current alternative if it satisfies the dependency. If not, or if
there is no candidate version (for instance, because the current
alternative is a virtual package), and if the dependency is
unversioned, attempt to install the highest-priority package^[12]
whose candidate version provides the target of the current
alternative.
For instance, say we are attempting to resolve "Depends: exim |
mail-transport-agent". aptitude will first attempt to install the
package exim. If exim is not available, aptitude will then attempt to
install the highest-priority package whose candidate version provides
exim. If there is no such package, aptitude will install the
highest-priority package whose candidate version provides the virtual
package mail-transport-agent. On the other hand, suppose that the
dependency is "Depends: exim (>= 2.0.0) | mail-transport-agent", but
only version 1.0 of exim is available. In this case, aptitude will not
install exim (because the version does not match), nor will it attempt
to install packages providing exim (because virtual packages cannot
match a dependency with a version restriction). Thus, aptitude will
fall back to installing the highest-priority package whose candidate
version provides mail-transport-agent.
4. If a package was installed by the previous step, resolve its
dependencies using this algorithm, then stop.
While this technique very often solves all the outstanding package
dependencies, it can fail in a number of common circumstances.
* Conflicts are resolved by removing the package that is the target of
the conflict. But now other packages that depend on this package have
unresolved dependencies; the immediate resolver makes no attempt to
fix them.
* A dependency might not be satisfiable due to version restrictions and
due to the limitation that only candidate versions are considered. For
instance, say that versions 1.0 and 2.0 of fileutils are available,
that the candidate version is 1.0, and that the package octopus
declares a dependency "Depends: fileutils (>= 2.0)". Immediate
resolution is unable to resolve this dependency: it will never
consider version 2.0 of the package, since that is not the candidate
version.
The interactive dependency resolver can solve these situations and more.
When there are broken dependencies left over, or when immediate dependency
resolution is disabled, the interactive resolver will automatically start
searching for a solution. The next section describes how to use the
interactive dependency resolver.
Resolving Dependencies Interactively
If a dependency problem arises that cannot be handled using the immediate
dependency resolver, aptitude can assist you in resolving it. As soon as a
problem occurs, a red bar will appear at the bottom of the screen with a
summary of aptitude's suggestion about how to fix it. For instance, in the
following screenshot, aptitude is indicating that it can resolve the
situation by keeping two packages at their current versions.

You can guide the dependency resolver to a solution of which you approve
by approving or rejecting the individual actions of a solution. If you
approve an action, the resolver will choose it whenever possible, ignoring
alternatives (when there are several approved alternatives, any one of
them could be chosen). On the other hand, if you reject an action, the
resolver will never choose that action.
To reject an action, highlight it and press r; the rejection can be
cancelled by pressing r again. Similarly, select an action and press a to
approve it; press a again to restore its original state. You can undo
either action by using Undo -> Undo (Control+u) while the resolver screen
is active. If you cancel a rejection or an approval, any solutions that
were ignored will be available the next time that you generate a new
solution.
[Note] Note
By default, the resolver rejects actions that change the state of
held packages, or that install forbidden versions of packages. You
can override these rejections, thus allowing the hold or forbidding
to be automatically overridden, in the same way that you would
override any other rejection. Setting the configuration option
Aptitude::ProblemResolver::Allow-Break-Holds to true will disable
this behavior, meaning that the resolver will always break holds
(albeit at a penalty, see
Aptitude::ProblemResolver::BreakHoldScore).
Rejected actions are colored red and marked with an "R", while approved
actions are colored green and marked with an "A". You can see this in the
following screenshot, where the action "keep gstreamer0.8-cdparanoia at
its current version" has been rejected, and the action "keep sound-juicer
at its current version" has been approved.

Rejections and approvals only affect newly generated solutions. You can
tell when a new solution will be generated by examining the indicator in
the lower left hand corner of the screen: if there is a number in
parentheses, it is the number of solutions that have been generated. Thus,
when the number outside the parentheses and the number inside are
identical (as above), pressing . will generate a new solution. If there is
no number in parentheses (for instance, the indicator reads [1/5]), then
there are no more solutions to generate. At any time, you can select the
last generated solution by pressing >, and the first generated solution by
pressing <.

The state of the problem resolver is discarded when you modify
the state of any package. If you mark a package for
installation, for upgrade, for removal, etc, the resolver will
forget all of your rejections and approvals, as well as all
the solutions that have been generated so far.

Costs in the interactive dependency resolver
Costs and cost components
The cost of a solution produced by the interactive dependency resolver is
a value that aptitude uses to determine how "bad" that solution is.
Solutions that are "better" are always displayed before solutions that are
"worse". The cost of solutions is defined in the configuration option
Aptitude::ProblemResolver::SolutionCost.
Some typical costs are shown in Example 2.1, "Sample resolver costs".
Example 2.1. Sample resolver costs
The default cost, sorting solutions by their safety cost, then by their
apt pin priority:
safety, priority
Remove as few packages as possible, then cancel as few actions as
possible:
removals, canceled-actions
Sort solutions by the number of packages they remove plus twice the number
of actions they cancel.
removals + 2 * canceled-actions
As can be seen from the above examples, a cost is not necessarily a single
number. In fact, a cost consists of one or more cost components, each of
which is a number associated with the solution. When sorting solutions,
the resolver examines cost components in order, proceeding to later
components only if the earlier ones are equal. For instance, in the cost
"removals, canceled-actions", solutions with fewer removals always appear
before solutions with more removals, regardless of how many canceled
actions they have. However, solutions with the same number of removals are
sorted so that solutions with fewer canceled actions appear first.
Cost components come in two flavors: basic cost components and compound
cost components.
Basic components simply name some property of the solution, such as
"upgrades" or "removals". A list of built-in basic components provided by
aptitude can be found in Table 2.1, "Basic cost components". You can also
create your own cost components using the add-to-cost-component and
raise-cost-component hints; see the section called "Configuring resolver
hints" for details.
Each basic component is either a counter or a level. Counters count how
many of a solution's actions meet some condition (such as removing
packages or installing new packages), while levels associate a number with
each action and compute the highest number associated with any action in
the solution.
Table 2.1. Basic cost components
+----------------------------------------------------------------------------------+
| Name | Type | Description |
|--------------------+-------+-----------------------------------------------------|
| | |Counts the number of holds that the solution breaks, |
|broken-holds |Counter|if the resolver is allowed to break holds |
| | |(Aptitude::ProblemResolver::Allow-Break-Holds). |
|--------------------+-------+-----------------------------------------------------|
| | |Counts the number of pending actions that the |
|canceled-actions |Counter|solution cancels (keeping packages at their current |
| | |version). |
|--------------------+-------+-----------------------------------------------------|
|installs |Counter|Counts the number of packages that the solution |
| | |installs. |
|--------------------+-------+-----------------------------------------------------|
|non-default-versions|Counter|Counts the number of versions that the solution |
| | |installs or upgrades from non-default sources. |
|--------------------+-------+-----------------------------------------------------|
| | |A value that increases as the apt pin priority of a |
|priority |Level |version decreases. Specifically, this is computed by |
| | |negating the pin priority (so, e.g., if the pin |
| | |priority is 500, this component will compute -500). |
|--------------------+-------+-----------------------------------------------------|
|removals |Counter|Counts the number of packages that the solution |
| | |removes. |
|--------------------+-------+-----------------------------------------------------|
|removals-of-manual |Counter|Counts the number of manually installed packages that|
| | |the solution removes. |
|--------------------+-------+-----------------------------------------------------|
| | |A broad heuristic that increases as actions become |
|safety |Level |less "safe"; see the section called "Safety costs" |
| | |for details. |
|--------------------+-------+-----------------------------------------------------|
|upgrades |Counter|Counts the number of packages that the solution |
| | |upgrades. |
+----------------------------------------------------------------------------------+
Compound components are built by combining the values of basic components.
For instance, removals + canceled-actions adds the components removal and
canceled-actions, resulting in a component that counts the number of
removals and canceled actions. Compound components combine counters by
adding them together and levels by taking their maximum value, as shown in
Figure 2.11, "Syntax of compound cost components".
[Note] Note
It is an error to add two levels, or to take the maximum of two
counters, or to combine levels and counters in any way. For
instance, the costs removals + safety and max(upgrades, installs)
will be treated as errors and ignored by the resolver.^[13]
Figure 2.11. Syntax of compound cost components
Add two or more basic costs:
[scale1]*cost1 + [scale2]*cost2 + ...
Take the maximum value of two or more basic costs:
max([scale1]*cost1, [scale2]*cost2, ...)
Note that each individual basic component can be multiplied by a scaling
factor before it is combined with other components. This can be used to
control the trade-offs that the resolver makes between costs. For
instance, a cost of 2*removals + 3*upgrades says that three removals are
exactly as "bad" as two upgrades. Solutions that contain four removals and
one upgrade will be considered equivalent to solutions containing one
removal and three upgrades, since both have a cost of eleven.
Safety costs
Figure 2.12. Safety cost levels
Safety cost levels
The safety cost component is a heuristic estimate of how "safe" or
"unsafe" a solution is. Safety costs can be thought of as a way of
dividing solutions into several numbered "levels", where "less safe"
levels are given higher numbers. Figure 2.12, "Safety cost levels" shows
how this works with aptitude's default settings.
[Tip] Tip
Safety cost levels are just one way to control the order in which
dependency solutions are returned. See the section called "Costs in
the interactive dependency resolver" for a full description of how
to change the order in which aptitude sorts solutions.
By default, aptitude initializes the resolver with a "reasonable" set of
safety cost levels. They are:
Table 2.2. Default safety cost levels
+------------------------------------------------------------------------------+
| Cost | Description | Configuration option |
|level | | |
|------+---------------------+-------------------------------------------------|
| |Solutions that | |
| |include only "safe" | |
| |actions (installing | |
|10,000|the default target |Aptitude::ProblemResolver::Safe-Level, |
| |for a package or |Aptitude::ProblemResolver::Remove-Level |
| |keeping a package at | |
| |its current version) | |
| |and package removals.| |
|------+---------------------+-------------------------------------------------|
| |The solution that | |
|20,000|cancels all the |Aptitude::ProblemResolver::Keep-All-Level |
| |user's actions. | |
|------+---------------------+-------------------------------------------------|
| |Solutions that break | |
|40,000|holds set by the user|Aptitude::ProblemResolver::Break-Hold-Level |
| |or install forbidden | |
| |versions. | |
|------+---------------------+-------------------------------------------------|
| |Solutions that | |
| |install packages from| |
|50,000|non-default versions |Aptitude::ProblemResolver::Non-Default-Level |
| |(such as | |
| |"experimental", for | |
| |instance). | |
|------+---------------------+-------------------------------------------------|
|60,000|Solutions that remove|Aptitude::ProblemResolver::Remove-Essential-Level|
| |Essential packages. | |
+------------------------------------------------------------------------------+
If a solution qualifies for several safety cost levels, it will be placed
in the highest one, that is, the one that appears last. For example, a
solution that upgrades one package to its default version and breaks a
hold on a second package will be placed at level 40,000. You can adjust
the levels of individual versions using resolver hints; see the section
called "Configuring resolver hints" for details. The default levels are
illustrated in Figure 2.12, "Safety cost levels".
Configuring the interactive dependency resolver
Configuring resolver hints
To improve the quality of the dependency solutions that you receive, you
can provide hints to the interactive dependency resolver. These hints can
alter the priorities of the resolver, biasing it more strongly in favor of
one version or package, or they can be used to "pre-load" the resolver
with rejections and approvals, as if you had entered the resolver and
manually rejected or approved various versions.
Hints are stored in the apt configuration file, /etc/apt/apt.conf, in the
configuration group "Aptitude::ProblemResolver::Hints" (see the section
called "Configuration file reference" for details on the configuration
file).
Each resolver hint consists of an action, a target, and an optional
version. A hint is written like this: "action target [version]". To apply
a resolver hint, aptitude locates one or more packages using the value of
target, chooses one or more versions of those packages using the value of
version, and finally performs the given action.
The action field of a resolver hint may be one of the following:
1. "approve": Approve the version, as if the command Resolver -> Toggle
Approved (a) had been invoked on it.
2. "reject": Reject the version, as if the command Resolver -> Toggle
Rejected (r) had been invoked on it.
3. "discard": Discard every solution containing the version. Differs from
"reject" in that it is not visible to the user and cannot be modified
interactively.
4. "increase-safety-cost-to number": increase the safety cost of any
solution that contains the version to number; if its safety cost is
already higher than number, this hint has no effect. The safety cost
can be used (and is used by default) to control the order in which
solutions appear; see the section called "Costs and cost components"
and the section called "Safety costs" for details.
Several special cost levels can be chosen by name:
a. conflict, discard: instead of changing the safety cost, discard
solutions containing the version as if the "discard" hint had
been applied.
b. maximum: the highest safety cost.
c. minimum: the lowest safety cost. All searches start at this cost,
so "increasing" a version to this cost has no effect. However,
this value can also be used when adjusting the predefined cost
levels: for instance, setting
Aptitude::ProblemResolver::Remove-Level to "minimum" will cause
removed packages to have no effect on the safety cost of a
solution.
[Note] Note
The increase-safety-cost-to hint is applied in addition to any
default safety cost that is due to the selected action. For
instance, a hint that increases the safety cost of "install hal
from experimental" to 15,000 will have no effect, because that
action already has a safety cost of 50,000 (assuming that this
version of hal is not the default candidate version).
5. "number": add the given number to the version's score, biasing the
resolver in favor of it or (with a negative number) away from it. For
instance, the hint 200 emacs adds 200 to the score of emacs, whereas
the hint -10 emacs subtracts 10 from its score.
If target field of a resolver hint contains a question mark ("?") or tilde
("~"), it is considered to be a search pattern and all matching package
versions are considered. Otherwise, it is considered to be the name of a
package to select. So the target "g++" will select only the g++ package,
but the target "?section(non-free)" will select any package in the
non-free section. See the section called "Search patterns" for more
information on search patterns.
If the version field is not present, then all versions of the package are
affected by the hint. Otherwise, it may have any of the following forms:
1. "/archive": the hint only affects versions that are available in the
given archive.
2. "<version": the hint only affects versions whose version number is
less than version.
3. "<=version": the hint only affects versions whose version number is
less than or equal to version.
4. "=version": the hint only affects versions whose version number is
version.
5. "<>version": the hint only affects versions whose version number is
not version.
6. ">=version": the hint only affects versions whose version number is
greater than or equal to version.
7. ">version": the hint only affects versions whose version number is
greater than version.
8. ":UNINST": instead of affecting any of the versions of target, the
hint affects the decision to remove target. For instance, "reject
aptitude :UNINST" will prevent the resolver from attempting to remove
aptitude.
9. "version": the hint only affects versions whose version number is
version.
Search patterns
When you search for a package or set a display limit in aptitude, the
string you enter is known as a "search pattern". While the most basic
usage of search patterns is to match packages by name, aptitude allows you
to create much more complex searches. In addition to the visual interface,
some command-line operations can use search patterns; see Command-line
reference for details.
A search pattern consists of one or more conditions (sometimes known as
"terms"); packages match the pattern if they match all of its terms. Terms
generally start with a question mark ("?"), followed by the name of the
match term, which describes the search that the term performs: for
instance, the term ?name matches package names, while the term ?version
matches package versions. Finally, any additional parameters to the search
term are placed in parentheses (see the documentation of individual terms
for details of what each term's parameters mean).
[Note] Note
Text with no leading "?" also forms a search pattern: aptitude will
treat each word (or quoted string) as the argument to a ?name
pattern, which searches for a package whose name matches the text
when the text is interpreted as a regular expression.
[Warning] Warning
The behavior of aptitude when given a search pattern without a
leading "?" (or "~") is provided as a convenience for
interactive use and will change in future releases; scripts that
invoke aptitude should explicitly name the search strategy they
want to use. That is, scripts should search for "?name(coq)"
rather than "coq").
Searching for strings
Many search terms take a string as a parameter and match it against one or
more fields of a package. Strings can be entered either with or without
double quotes ("""), so "?name(scorch)" and "?name("scorch")" will perform
the same search. If you enter a search string using double quotes, you can
include a literal double-quote in the search string by placing a backslash
("\") immediately before it: for instance, "?description("\"easy\"")" will
match any package whose description contains the string ""easy"".
If you enter a "bare" string, one not surrounded by double quotes, then
aptitude will consider the string to have "ended" when it encounters the
closing parenthesis or the comma before a second argument to the search
term. ^[14] To remove the special meaning of these characters, place a
tilde ("~") directly before them. For instance, "?description(etc))" is a
syntax error, because the first ")" ends the ?description term, and the
second ")" does not correspond to any "(". In contrast,
"?description(etc~))" matches any package whose description contains the
text "etc)". There are additional considerations if you are using the
shorthand notation for a term; see the section called "Shorthand for
search terms" for details.
Most textual searches (for package names, descriptions, etc) are performed
using case-insensitive regular expressions. A regular expression will
match against a field if any portion of the field matches the expression;
for instance, "ogg[0-9]" will match "libogg5", "ogg123", and "theogg4u".
Some characters have a special meaning within regular expressions ^[15] ,
so if you want to match them in searches you need to backslash-escape
them: for instance, to find "g++", you should use the pattern "g\+\+".
The characters "!" and "|" have special meanings within search patterns.
In order to include these characters in an unquoted string, you can place
a tilde ("~") directly before them. For instance, to match packages whose
description contains either "grand" or "oblique", use the pattern
"?description(grand~|oblique)". However, you will probably find it more
convenient to simply use a quoted string in these cases:
"?description("grand|oblique")".
Shorthand for search terms
Some search terms can be written using "short" forms, which consist of a
tilde ("~") followed by a single character that identifies the term, and
finally the arguments (if any) to the term. For instance, the short form
of ?name(aptitude) is ~n aptitude.
When writing a term using its short form, tilde characters and
"whitespace" -- that is, space characters, tabs, and so on -- will break
the term off and start a new term. For instance, "~mDaniel Burrows" will
match any package whose maintainer field contains "Daniel" and whose name
contains "Burrows", while "~i~napt" matches installed packages whose name
contains apt. To include whitespace characters in the search expression,
you can either place a tilde in front of it (as in Daniel~ Burrows) or
place quotation marks around it (as in "Debian Project" or even Debian"
"Project). Inside a quoted string, the backslash character ("\") can be
used to cancel the special meaning of the quotation mark: for instance,
~d"\"email" will match any package whose description contains a quotation
mark followed immediately by email. ^[16]
[Note] Note
Question marks ("?") will not end the short form of a term, even if
they are followed by the name of a search term. For instance,
"~napt?priority(required)" will match all packages whose name
matches the regular expression "apt?priority(required)". To combine
a short query term with a search term specified by name, add one or
more spaces between the two terms, as in
"~napt ?priority(required)", or place quotation marks around the
text (if any) following the short form of a term, as in
"~n"apt"?priority(required)".
Table 2.3, "Quick guide to search terms" lists the short form of each
search term.
Searches and versions
By default, a pattern matches a package if any version of the package
matches the pattern. However, some patterns will restrict their
sub-patterns to only match against some versions of a package. For
instance, the search term ?depends(pattern) will select any package that
depends on a package matching pattern. However, pattern will only be
checked against the versions of the package that actually satisfy a
dependency. This means that if foo depends on bar (>= 3.0) and versions
2.0, 3.0, and 4.0 of bar are available, then in the search pattern
?depends(?version(2\.0)), only versions 3.0 and 4.0 will be tested against
?version(2\.0), and hence foo will not be found by this search.
It matters which versions are checked because, as in the example above,
some patterns will match one version but not another. For instance, the
pattern ?installed will only match the version of the package (if any)
that is currently installed. Similarly, the pattern
?maintainer(maintainer) will only match versions that have the given
maintainer. Normally all versions of a package have the same maintainer,
but this is not always the case; in fact, any search pattern that examines
the fields of a package (other than its name, of course) will behave this
way, because all the fields of a package can change between versions.
To test a pattern against all the versions of a package, even if the
pattern would normally be tested against only some of the versions, use
the ?widen term. For instance, ?depends(?widen(?version(2\.0))) will match
any package A that depends on a package B, where B has a version matching
2.0, regardless of whether that version actually satisfies A's dependency.
On the other hand, the ?narrow term restricts the versions that its
sub-pattern is matched against: ?narrow(?installed,
?depends(?version(ubuntu))) will match any package whose installed version
has a dependency that can be satisfied by a package whose version string
contains "ubuntu".
[Note] Note
There is a subtle, but important, distinction between matching a
pattern against a package, and matching it against all the versions
of that package. When a pattern is matched against a package, each
of its terms is matched against the package, and so each term will
match if any version of the package matches. In contrast, when a
pattern is matched against each version of a package, it will
successfully match if it matches when all its terms are matched
against the same version of the package.
For example: suppose that version 3.0-1 of the package aardvark is
installed, but that version 4.0-1 is available. Then the search
expression ?version(4\.0-1)?installed matches aardvark, because
?version(4\.0-1) matches against version 4.0-1 of aardvark, while
?installed matches against version 3.0-1. On the other hand, this
expression does not match against all the versions of aardvark,
because no single version is installed and also has a version
number of 4.0-1.
Explicit search targets
Some particularly complex searches can be expressed in aptitude using
explicit targets. In normal search expressions, there is no way to refer
to the package or version that is currently being tested. For instance,
suppose that you want to search for all packages P that depend on a second
package Q such that Q recommends P. Clearly you need to start out with a
?depends(...) term. But the term filling in the ... needs to somehow
select packages that are identical to the one being matched against
?depends. When describing the goal above, I dealt with this by giving the
packages names, calling them P and Q; terms with explicit targets do
exactly the same thing. ^[17]
An explicit target is introduced by the ?for term:
Figure 2.13. Syntax of the ?for term
?for variable: pattern
This behaves exactly like pattern, but variable can be used within pattern
to refer to the package or version that pattern is being matched against.
You can use variable in two ways:
1. The term ?= will match exactly the package or version indicated by the
given variable. Specifically: if the corresponding ?for term is
limited to a particular version, then ?= will match either that
version (if ?= is limited) or the whole package; otherwise it will
match any version of the package.
See Example 2.2, " Use of the ?= term. " for an example of how to use
?=.
2. The term ?bind(variable, pattern) will match any package or version if
the value of variable matches against pattern.
For ?-style terms, a shorthand form is available. The expression
?bind(variable, ?term[(args)]) can be replaced by
?variable:term(args).
See Example 2.3, "Use of the ?bind term" for an example of how to use
?bind.

+--------------------------------------------------------------------------------+
name
Matches packages whose names match the regular expression name.
This is the "default" search mode and is used for patterns that
don't start with ~.
[Note] Note
To match packages whose names contain several different
substrings, use the ?name term (described below); for
instance, "?name(apti)?name(tude)" will match any package
whose name contains both "apti" and "tude".
?=variable
Matches packages that correspond to the value of variable, which
must be bound by an enclosing ?for. For instance, ?for x:
?depends( ?recommends( ?=x ) ) will match any package x that
depends on a package which recommends x.
For instance, the following search expression matches packages
that conflict with themselves:
Example 2.2. Use of the ?= term.
?for x: ?conflicts(?=x)
See the section called "Explicit search targets" for more
information.
?not(pattern), !pattern
Matches packages which do not match the pattern pattern. For
instance, "?not(?broken)" selects packages that are not "broken".
[Note] Note
To include a "!" in a search string, it must be "escaped"
by placing a tilde ("~") in front of it; otherwise,
aptitude will consider it to be part of a ?not term. For
instance, to select packages whose description contains
"extra!", use "?description(extra~!)".
?and(pattern1, pattern2), pattern1 pattern2
Matches packages that match both pattern1 and pattern2.
?or(pattern1, pattern2), pattern1 | pattern2
Matches packages that match either pattern1 or pattern2.
[Note] Note
To use the character "|" in a regular expression, it must
be "escaped" to prevent aptitude from creating an OR term
from it: "~|".
(pattern)
Matches pattern. For instance, "opengl (perl|python)" matches any
package whose name contains opengl, and also contains either perl
or python.
?action(action), ~aaction
Matches packages upon which the given action is going to be
performed. action can be "install", "upgrade", "downgrade",
"remove", "purge", "hold" (tests whether a package has been placed
on hold), or "keep" (tests whether a package will be unchanged).
Note that this only tests whether an action is actually queued up
to be performed on a package, not whether it could be performed.
Thus, for instance, ?action(upgrade) matches exactly those
packages that you have already decided to upgrade, not packages
which could be upgraded in the future (for that, use ?upgradable).
?all-versions(pattern)
Matches any package whose versions all match the given expression.
Each version of a package will be separately tested against
pattern, and the package will match if all of its versions match.
Packages without versions, such as virtual packages, will always
be matched by this search term.
This term may not be used in a context in which the versions to
match against have already been narrowed, such as within ?depends
or ?narrow. However, it may always be used within ?widen.
?any-version(pattern)
Matches a package if any one of its versions matches the enclosed
pattern. This is the dual to ?all-versions.
This term may not be used in a context in which the versions to
match against have already been narrowed, such as within ?depends
or ?narrow. However, it may always be used within ?widen.
[Note] Note
This term is closely related to ?narrow. In fact,
?any-version(pattern1 pattern2) is exactly the same as
?narrow(pattern1, pattern2).
?architecture(architecture), ~rarchitecture
Matches package versions for the given architecture. For instance,
"?architecture(amd64)" matches amd64 packages, while
"?architecture(all)" matches arch-independent packages. Also
accepts the special values native and foreign.
?archive(archive), ~Aarchive
Matches package versions which are available from an archive that
matches the regular expression archive. For instance,
"?archive(testing)" matches any package available from the testing
archive.
?automatic, ~M
Matches packages which were automatically installed.
?bind(variable, pattern), ?variable:term-name[(args)]
Matches any package or version if the given pattern matches the
package or version bound to variable, which must be defined in an
enclosing ?for.
Example 2.3. Use of the ?bind term
?for x: ?depends(?depends(?for z: ?bind(x, ?depends(?=z))))
?for x: ?depends(?depends(?for z: ?x:depends(?=z)))
The two search patterns in the above example both match any
package x such that x depends on a package y which in turn depends
on a package z such that x also depends directly on z. The first
pattern uses ?bind directly, while the second one uses an
equivalent shorthand syntax.
See the section called "Explicit search targets" for more
information.
?broken, ~b
Matches packages that are "broken": they have an unfulfilled
dependency, predependency, breaks, or conflict.
?broken-depType, ~BdepType
Matches packages which have an unfulfilled ("broken") dependency
of the given depType. depType can be "depends", "predepends",
"recommends", "suggests", "breaks", "conflicts", or "replaces".
?broken-depType(pattern), ~DB[depType:]pattern
Matches packages with an unsatisfied dependency of type depType on
a package matching pattern. depType may be any one of the
dependency types listed in the documentation of ?broken-depType.
?conflicts(pattern), ~Cpattern
Matches packages which conflict with a package matching the given
pattern. For instance,
"?conflicts(?maintainer(dburrows@debian.org))" matches any package
which conflicts with a package I maintain.
?config-files, ~c
Matches packages which have been removed, but whose configuration
files remain on the system (ie, they were removed but not purged).
?depType(pattern), ~D[depType:]pattern
depType may be any one of the dependency types given in the
documentation of ?broken-depType, as well as provides: for
instance, ?depends(libpng3) will match any package that depends on
libpng3. If the short form (~D) is used and depType is not
present, it defaults to depends.
If depType is "provides", matches packages that provide a package
matching pattern (the equivalent of ?provides). Otherwise, matches
packages which declare a dependency of type depType upon a package
version which matches pattern.
?description(description), ~ddescription
Matches packages whose description matches the regular expression
description.
?essential, ~E
Matches Essential packages.
?exact-name(name)
Matches packages named name. This is similar to ?name, but the
name must match exactly. For instance, the following pattern will
match only the package apt; with ?name, it would also match
aptitude, uvccapture, etc.
Example 2.4. Use of the ?exact-name term
?exact-name(apt)
?false, ~F
This term does not match any package. ^[18]
?for variable: pattern
Matches pattern, but the given variable may be used inside pattern
to refer to the package or package version this term to.
You can use variable in two ways. To apply a ?-style term to the
variable, write ?variable:term-name(args); for instance,
?x:depends(apt). In addition, the term ?=variable will select any
package or version that matches the value of the given variable.
For instance, the following term will match any package x that
both depends and recommends a second package y.
Example 2.5. Use of the ?for term
?for x: ?depends( ?for y: ?x:recommends( ?=y ) )
See the section called "Explicit search targets" for more
information.
?garbage, ~g
Matches packages which are not installed, or which were
automatically installed and are not depended upon by any installed
package.
?installed, ~i
Matches package versions which are currently installed.
Since all versions are tested by default, this normally matches
packages which are currently installed.
?maintainer(maintainer), ~mmaintainer
Matches packages whose Maintainer field matches the regular
expression maintainer. For instance, "?maintainer(joeyh)" will
find all packages maintained by Joey Hess.
?multiarch(multiarch)
Matches packages with the multi-arch capability specified by
multiarch. For instance, "?multiarch(foreign)" will find all
packages which can satisfy dependencies of packages for another
architecture. "?multiarch(none)" will select packages with no
multi-arch capability.
?narrow(filter, pattern), ~S filter pattern
This term "narrows" the search to package versions matching
filter. In particular, it matches any package version which
matches both filter and pattern. The string value of the match is
the string value of pattern.
?name(name), ~nname
Matches packages whose name matches the regular expression name.
For instance, most of the packages that match "?name(^lib)" are
libraries of one sort or another.
?new, ~N
Matches packages which are "new": that is, they have been added to
the archive since the last time the list of packages was cleared
using Actions -> Forget new packages (f) or the command-line
action forget-new.
?obsolete, ~o
This term matches any installed package which is not available in
any version from any archive. These packages appear as "Obsolete
or Locally Installed" in the visual interface.
?origin(origin), ~Oorigin
Matches package versions whose origin matches the regular
expression origin. For instance, "!?origin(debian)" will find any
unofficial packages on your system (packages not from the Debian
archive).
?provides(pattern), ~Ppattern
Matches package versions which provide a package that matches the
pattern. For instance, "?provides(mail-transport-agent)" will
match all the packages that provide "mail-transport-agent".
?priority(priority), ~ppriority
Matches packages whose priority is priority; priority must be
extra, important, optional, required, or standard. For instance,
"?priority(required)" matches packages whose priority is
"required".
?reverse-depType(pattern), ~R[depType:]pattern
depType may be either "provides" or one of the dependency types
given in the documentation of ?broken-depType. If depType is not
present, it defaults to depends.
If depType is "provides", matches packages whose name is provided
by a package version matching pattern. Otherwise, matches packages
which a package version matching pattern declares a dependency of
type depType upon.
?reverse-broken-depType(pattern), ?broken-reverse-depType(pattern),
~RB[depType:]pattern
depType may be either "provides" or one of the dependency types
given in the documentation of ?broken-depType. If depType is not
present, it defaults to depends.
Matches packages which a package version matching pattern declares
an unsatisfied dependency of type depType upon.
?section(section), ~ssection
Matches packages whose section matches the regular expression
section.
?source-package(name)
Matches packages whose source package name matches the regular
expression name.
?source-version(version)
Matches packages whose source version matches the regular
expression version.
?tag(tag), ~Gtag
Matches packages whose Tag field matches the regular expression
tag. For instance, the pattern ?tag(game::strategy) would match
strategy games.
For more information on tags and debtags, see
http://debtags.alioth.debian.org.
?task(task), ~ttask
Matches packages that appear in a task whose name matches the
regular expression task.
?term(keyword)
This term performs a full-text search for keyword in the apt
package cache. When used with "aptitude search", Search -> Limit
Display (l) in the curses front-end, or typed into a package
search box in the GTK+ front-end, this term will allow aptitude to
accelerate the search using a Xapian index.
?term-prefix(keyword)
This term performs a full-text search for any keyword beginning
with keyword in the apt package cache. When used with "aptitude
search", Search -> Limit Display (l) in the curses front-end, or
typed into a package search box in the GTK+ front-end, this term
will allow aptitude to accelerate the search using a Xapian index.
This is similar to ?term, but matches extensions of the keyword.
For instance, the following search pattern will match any package
indexed under the keywords hour, hourglass, hourly, and so on:
Example 2.6. Use of the ?term-prefix term
?term-prefix(hour)
?true, ~T
This term matches any package. For instance,
"?installed?provides(?true)" matches installed packages which are
provided by any package.
?upgradable, ~U
This term matches any installed package which can be upgraded.
?user-tag(tag)
This term matches any package that is marked with a user-tag
matching the regular expression tag.
?version(version), ~Vversion
Matches any package version whose version number matches the
regular expression version, with the exceptions noted below. For
instance, "?version(debian)" matches packages whose version
contains "debian".
The following values of version are treated specially. To search
for version numbers containing these values, preface the value
with a backslash; for instance, to find packages whose version
number contains CURRENT, search for \CURRENT.
* CURRENT matches the currently installed version of a package,
if any.
* CANDIDATE matches the version, if any, of the package that
will be installed if you press + on the package or run
aptitude install on it.
* TARGET matches the version of a package that is currently
targeted for installation, if any.
?virtual, ~v
Matches any package which is purely virtual: that is, its name is
provided by a package or mentioned in a dependency, but no package
of that name exists. For instance, "?virtual!?provides(?true)"
matches packages which are virtual and are not provided by any
package: ie, packages which are depended upon but do not exist.
?widen(pattern), ~Wpattern
"Widens" the match: if the versions to match against have been
limited by an enclosing term (such as ?depends), these limits are
dropped. Thus, ?widen(pattern) matches a package version if
pattern matches any version of that package.
Customizing aptitude
Customizing the package list
The package list can be heavily customized: how packages are displayed,
how the package hierarchy is formed, how packages are sorted, and even how
the display is organized are all open to change.
Customizing how packages are displayed
This section describes how to configure the contents and format of the
package list, status line, and header line, as well as the output of
aptitude search.
The format of each of these locations is defined by a "format string". A
format string is a string of text containing %-escapes such as %p, %S, and
so on. The resulting output is created by taking the text and replacing
the %-escapes according to their meanings (given below).
A %-escape can either have a fixed size, in which case it is always
replaced by the same amount of text (with extra space characters added to
fill it out as necessary), or it can be "expandable", meaning that it
takes up the space that is not claimed by fixed-size columns. If there are
several expandable columns, the extra space is divided evenly between
them.
All %-escapes come with a default size and/or expandability. The size of a
%-escape can be changed by writing it between the % and the character
identifying the escape; for instance, %20V generates the candidate version
of the package, 20 characters wide. Placing a question mark (?) between
the % and the character identifying the escape causes the column's "basic"
width to vary depending on its content. Note that the resulting columns
might not line up vertically!
If you want a particular %-escape to be expandable, even though it
normally has a fixed width, place a pound sign (ie, "#") immediately after
it. For instance, to display the candidate version of a package, no matter
how long it is, use the format string %V#. You can also place # after
something that is not a %-escape; aptitude will "expand" the text
preceding the # by inserting extra spaces after it.
In summary, the syntax of a %-escape is:
%[width][?]code[#]
The configuration variables Aptitude::UI::Package-Display-Format,
Aptitude::UI::Package-Status-Format, and
Aptitude::UI::Package-Header-Format define the default formats the package
list, the header at the top of the package list, and the status line below
the package list respectively. To change how the results of an aptitude
search command are displayed, use the -F option.
The following %-escapes are available in format strings:
[Note] Note
Some of the descriptions below refer to "the package". In the GUI,
this is either the package being displayed or the currently
selected package; in the command-line search, this is the package
being displayed.
Escape Name Default size Expandable Description
This is not really an
escape; it simply inserts
%% Literal % 1 No a percent sign into the
output at the point at
which it occurs.
In some circumstances, a
display format string
will have "parameters":
for instance, in the
command-line search, the
%#number Parameter Variable No groups matched by the
Replacement search are used as
parameters when
displaying the result.
This format code will be
replaced by the parameter
indicated by number.
A single-character flag
summarizing any action to
%a Action Flag 1 No be performed on the
package, as described in
Figure 2.10, "Values of
the "action" flag".
A somewhat more verbose

not currently available.
Outputs how much
additional space will be
%Z Size Change 9 No used or how much space
will be freed by
installing, upgrading, or
removing a package.
Customizing the package hierarchy
The package hierarchy is generated by a grouping policy: rules describing
how the hierarchy should be built. The grouping policy describes a
"pipeline" of rules; each rule can discard packages, create
sub-hierarchies in which packages reside, or otherwise manipulate the
tree. The configuration items Aptitude::UI::Default-Grouping and
Aptitude::UI::Default-Preview-Grouping set the grouping policies for newly
created package lists and preview screens, respectively. You can set the
grouping policy for the current package list by pressing G.
The grouping policy is described by a comma-separated list of rules:
rule1,rule2,.... Each rule consists of the name of the rule, possibly
followed by arguments: for instance, versions or section(subdir). Whether
arguments are required and how many arguments are required (or allowed)
depends on the type of rule.
Rules can be non-terminal or terminal. A non-terminal rule will process a
package by generating some part of the hierarchy, then passing the package
on to a later rule. A terminal rule, on the other hand, will also generate
part of the tree (typically items corresponding to the package), but does
not pass its package to a later rule. If no terminal rule is specified,
aptitude will use the default rule, which is to create the standard
"package items".
action
Groups packages according to the action scheduled on them;
packages that are not upgradable and will be unchanged are
ignored. This is the grouping that is used in preview trees.
architecture
Groups packages according to their architecture.
deps
This is a terminal rule.
Creates standard package items which can be expanded to reveal the
dependencies of the package.
filter(pattern)
Include only packages for which at least one version matches
pattern.
If pattern is "missing", no packages are discarded. This is a
backwards compatibility feature and may be removed in the future.
firstchar
Groups packages based on the first character of their name.
hier
Groups packages according to an extra data file describing a
"hierarchy" of packages.
pattern(pattern [=> title] [{ policy }] [, ...])
A customizable grouping policy. Each version of every package is
matched against the given patterns. The first match found is used
to assign a title to the package; packages are then grouped by
their title. Strings of the form \N that occur in title will be
replaced by the Nth result of the match. If title is not present,
it is assumed to be \1. Note that packages which do not match any
patterns will not appear in the tree at all.
Example 2.7. Use of pattern to group packages by their maintainer
pattern(?maintainer() => \1)
The example above will group packages according to their
Maintainer field. The policy pattern(?maintainer()) will do the
same thing, as the absent title defaults to \1.
Instead of => title, an entry may end with ||. This indicates that
packages matching the corresponding pattern will be inserted into
the tree at the same level as the pattern grouping, rather than
being placed in subtrees.
Example 2.8. Use of pattern with some packages placed at the top
level
pattern(?action(remove) => Packages Being Removed, ?true ||)
The example above will place packages that are being removed into
a subtree, and place all the other packages at the current level,
grouped according to the policies that follow pattern.
By default, all the packages that match each pattern are grouped
according to the rules that follow the pattern policy. To specify
a different policy for some packages, write the policy in braces
({}) after the title of the group, after the ||, or after the
pattern if neither is present. For instance:
Example 2.9. Use of the pattern grouping policy with sub-policies
pattern(?action(remove) => Packages Being Removed {},
?action(install) => Packages Being Installed, ?true || {status})
The policy in the above example has the following effects:
* Packages that are being removed are placed into a subtree
labeled "Packages Being Removed"; the grouping policy for
this subtree is empty, so the packages are placed into a flat
list.
* Packages that are being installed are placed into a subtree
labeled Packages Being Installed and grouped according to the
policies that follow pattern.
* All remaining packages are placed at the top level of the
tree, grouped according to their status.
See the section called "Search patterns" for more information on
the format of pattern.
priority
Groups packages according to their priority.
section[(mode[,passthrough])]
Groups packages according to their Section field.
mode can be one of the following:
none
Group based on the whole Section field, so categories
like "non-free/games" will be created. This is the
default if no mode is specified.
topdir
Group based on the part of the Section field before
the first / character; if this part of the Section is
not recognized, or if there is no /, the first entry
in the list Aptitude::Sections::Top-Sections will be
used instead.
subdir
Group based on the part of the Section field after
the first / character, if it is contained in the list
Aptitude::Sections::Top-Sections. If not, or if there
is no /, group based on the entire Section field
instead.
subdirs
Group based on the part of the Section field after
the first / character, if the portion of the field
preceding it is contained in the list
Aptitude::Sections::Top-Sections; if not, or if there
is no /, the entire field will be used. If there are
multiple / characters in the portion of the field
that is used, a hierarchy of groups will be formed.
For instance, if "games" is not a member of
Aptitude::Sections::Top-Sections, then a package with
a section of "games/arcade" will be placed under the
top-level heading "games", in a sub-tree named
"arcade".
If passthrough is present, packages which for some reason lack a
true Section (for instance, virtual packages) will be passed
directly to the next level of grouping without first being placed
in sub-categories.
status
Groups packages into the following categories:
* Security Updates
* Upgradable
* New
* Installed
* Not Installed
* Obsolete and Locally Created
* Virtual
source
Groups packages according to their source package name.
tag[(facet)]
Groups packages according to the Tag information stored in the
Debian package files. If facet is provided, then only tags
corresponding to that facet will be displayed, and packages
lacking this facet will be hidden; otherwise, all packages will be
displayed at least once (with tagless packages listed separately
from packages that have tags).
For more information on debtags, see
http://debtags.alioth.debian.org.
task
Creates a tree called "Tasks" which contains the available tasks
(information on tasks is read from debian-tasks.desc in the
package tasksel). The rule following task will create its
categories as siblings of Tasks.
versions
This is a terminal rule.
Creates standard package items which can be expanded to reveal the
versions of the package.
Customizing how packages are sorted
By default, packages in the package list or in the output of aptitude
search are sorted by name. However, it is often useful to sort them
according to different criteria (for instance, package size), and aptitude
allows you to do just that by modifying the sorting policy.
Like the grouping policy described in the previous section, the sorting
policy is a comma-separated list. Each item in the list is the name of a
sorting rule; if packages are "equal" according to the first rule, the
second rule is used to sort them, and so on. Placing a tilde character (~)
in front of a rule reverses the usual meaning of that rule. For instance,
priority,~name will sort packages by priority, but packages with the same
priority will be placed in reverse order according to name.
To change the sorting policy for an active package list, press S. To
change the default sorting for all package lists, set the configuration
option Aptitude::UI::Default-Sorting. To change the sorting policy for
aptitude search, use the --sort command-line option.
The available rules are:
installsize
Sorts packages by the estimated amount of size they require when
installed.
installsizechange
Sorts packages by the change in the installed size (estimated
amount of size required when installed), comparing the current
version (if installed) and the candidate version to be installed,
upgraded or removed.
debsize
Sorts packages by the size of the package.
name
Sorts packages by name.
priority
Sorts packages by priority.
version
Sorts packages according to their version number.
Customizing keybindings
The keys used to activate commands in aptitude can be customized in the
configuration file. Every command has an associated configuration variable
under Aptitude::UI::Keybindings; to change the keystroke bound to a
command, just set the corresponding variable to the keystroke. For
instance, to make the key s perform a search, set
Aptitude::UI::Keybindings::Search to "s". You can require the Control key
to be pressed by placing "C-" in front of the key: for instance, using
"C-s" instead of "s" would bind Search to Control+s instead of s. Finally,
you can bind a command to several keys at once using a comma-separated
list: for instance, using "s,C-s" would cause both s and Control+s to
perform a search.
The following commands can be bound to keys by setting the variable
Aptitude::UI::Keybindings::command, where command is the name of the
command to be bound:

Customizing text colors and styles
The colors and visual styles used by aptitude to display text can be
extensively customized. Each visual element has an associated "style",
which describes the particular colors and visual attributes that will be
used to display that element. Styles take the form of a list of color and
attribute settings. This list is not necessarily exhaustive; if some
colors or attributes are not explicitly specified, their values will be
taken from the surrounding visual context. In fact, most visual elements
have an "empty" style by default.
You can change the contents of a style by creating a configuration group
of the same name in the apt or aptitude configuration file. For instance,
the "MenuBorder" style is used to draw the visual border around drop-down
menus. By default, this border is drawn bold and white-on-blue. Placing
the following text in the configuration file would change it to
white-on-cyan:
Aptitude::UI::Styles {
MenuBorder {fg white; bg cyan; set bold;};
};
As you can see, a style's configuration group consists of a sequence of
instructions. The general classes of instructions are:
fg color
Sets the text foreground to the given color. See below for a list
of the colors known to aptitude.
bg color
Sets the text background to the given color. See below for a list
of the colors known to aptitude.
set attribute
Enables the given text attribute. See below for a list of the text
attributes known to aptitude.
clear attribute
Disables the given text attribute. See below for a list of the
text attributes known to aptitude.
flip attribute
Toggles the given text attribute: if it is enabled in the
surrounding element, it will be disabled, and vice versa. See
below for a list of the text attributes known to aptitude.
The colors that aptitude recognizes are black, blue, cyan, green, magenta,
red, white, and yellow ^[20]. In addition, you may specify default in
place of a background color to use the default terminal background (this
could be the default color, an image file, or even "transparent"). The
styles that aptitude recognizes are:
blink
Enables blinking text.
bold
Makes the foreground color of the text (or the background if
reverse video is enabled) brighter.
dim
May cause text to be extra-dim on some terminals. No effect has
been observed on common Linux terminals.
reverse
Swaps the foreground and background colors. Many visual elements
flip this attribute to perform common highlighting tasks.
standout
This enables "the best highlighting mode of the terminal". In
xterms it is similar, but not idential to, reverse video; behavior
on other terminals may vary.
underline
Enables underlined text.
You can select several attributes at once by separating them with commas;
for instance, set bold,standout;.
[Note] Note
As hinted at above, the interpretation of both styles and text
attributes is highly terminal-dependent. You may need to experiment
a bit to find out exactly what some settings do on your terminal.
The following styles can be customized in aptitude:
Figure 2.14. Customizable styles in aptitude
+----------------------------------------------------------------------------+
| Style | Default | Description |
|--------------------------+---------------+---------------------------------|
|Bullet |fg yellow; set |The style of the bullets in |
| |bold; |bulleted lists. |
|--------------------------+---------------+---------------------------------|
| | |The style of newer versions of |
| | |the package in the changelog |

|ChangelogNewerVersion |set bold; |only highlight newer versions of |
| | |the package if you have the |
| | |package |

Customizing the display layout
It is possible to rearrange the aptitude package list by making suitable
modifications to the configuration file.
Display elements
The layout is stored in the configuration group
Aptitude::UI::Default-Package-View, and consists of a list of display
elements:
Name Type {
Row row;
Column column;
Width width;
Height height;
additional options...
};
This creates a display element named Name; the type of element created is
determined by Type. The Row, Column, Width, and Height options must be
present; they determine where the display element is placed. (see below
for a detailed explanation of how display elements are arranged)
For examples of how to change the display layout, see the theme
definitions in the file /usr/share/aptitude/aptitude-defaults.
The following types of display elements are available:
Description
This display element will contain the "information area"
(typically a description of the currently selected package).
The option PopUpDownKey gives the name of a keyboard command which
will cause the display element to be shown or hidden. For
instance, setting this to ShowHideDescription will give the
current display element the same behavior as the default
information area. The option PopUpDownLinked gives the name of
another display element; the current element will be shown or
hidden whenever the other element is.
MainWidget
This is a placeholder for the "main" display element: typically
this is the list of packages. A display layout must contain
exactly one MainWidget element: no more, no less.
Static
A region of the screen which displays some text, possibly
containing formatting codes as described in the section called
"Customizing how packages are displayed". The text to display can
be given in the Columns option, or it can be stored in another
configuration variable specified by the ColumnsCfg option. The
color of the text is determined by the color named by the Color
option.
Static items can be displayed and hidden in the same way as
Description items, using the PopUpDownKey and PopUpDownLinked
options.
Placement of display elements
The display elements are arranged in a "table". The upper-left corner of
an element is in the cell given by its Row and Column options (typically
starting from row 0 and column 0, but this is not required). The width of
an element in cells is given by its Width option, and its height is given
by its Height option.
Once the display elements are arranged and have been given an initial
amount of space on the screen, there is likely to be space left over. If
there is extra vertical space, each row containing a display element whose
RowExpand option is true will be allocated a share of the extra space;
similarly, if there is extra horizontal space, each column containing a
display element whose ColExpand option is true will be allocated a share
of the extra space.
In the event that there is not enough space, every row and column whose
widgets all have their RowShrink or ColShrink options set to true will be
shrunk. If this is not enough, all rows and columns are shrunk to fit into
the available space.
If a display element is not expanded, but its row or column is, its
alignment is determined by the RowAlign and ColAlign options. Setting them
to Left, Right, Top, Bottom, or Center will tell aptitude where to place
the element within the row or column.
For instance, the following configuration group creates a static element
named "Header", which is three cells wide and will expand horizontally but
not vertically. It has the same color as other header lines and uses the
standard display format for header lines:
Header Static {
Row 0;
Column 0;
Width 3;
Height 1;
ColExpand true;
ColAlign Center;
RowAlign Center;
Color ScreenHeaderColor;
ColumnsCfg HEADER;
};
Display layout option reference
The following options are available for display elements:
ColAlign alignment;
alignment must be either Left, Right, or Center. If the row
containing the current display element is wider than the element
itself and ColExpand is false, the element will be placed within
the row according to the value of alignment.
If this option is not present, it defaults to Left.
ColExpand true|false;
If this option is set to true, the column containing this display
element will be allocated a share of any extra horizontal space
that is available.
If this option is not present, it defaults to false.
Color colorname;
This option applies to Static elements. colorname is the name of a
color (for instance, ScreenStatusColor) which should be used as
the "default" color for this display element.
If this option is not present, it defaults to
DefaultWidgetBackground.
ColShrink true|false;
If this option is set to true on each element in a column and
there is not enough horizontal space, the column will be shrunk as
necessary to fit the available space. Note that a column may be
shrunk even if ColShrink is false; it simply indicates that
aptitude should try shrinking a particular column before shrinking
other columns.
If this option is not present, it defaults to false.
Column column;
Specifies the leftmost column containing this display element.
Columns format;
This option applies to Static display elements for which the
ColumnsCfg option is not set. It sets the displayed contents of
the status item; it is a format string as described in the section
called "Customizing how packages are displayed".
ColumnsCfg HEADER|STATUS|name;
This option applies to Static display elements. It sets the
display format of the current element to the value of another
configuration variable: if it is HEADER or STATUS, the options
Aptitude::UI::Package-Header-Format and
Aptitude::UI::Package-Status-Format, repectively, are used;
otherwise, the option name is used.
If this option is not present, the value of the Columns option is
used to control the contents of the static item.
Height height;
Specifies the height of the current display element.
PopUpDownKey command;
This option applies to Description and Static display elements.
command is the name of a keyboard command (for instance,
ShowHideDescription). When this key is pressed, the display
element will be hidden if it is visible, and displayed if it is
hidden.
PopUpDownLinked element;
This option applies to Description and Static display elements.
element is the name of a display element. When element is
displayed, the current element will also be displayed; when
element is hidden, the current element will also be hidden.
Row row;
Specifies the uppermost row containing this display element.
RowAlign alignment;
alignment must be either Top, Bottom, or Center. If the row
containing the current display element is taller than the element
itself and RowExpand is false, the element will be placed within
the row according to the value of alignment.
If this option is not present, it defaults to Top.
RowExpand true|false;
If this option is set to true, the row containing this display
element will be allocated a share of any extra vertical space that
is available.
If this option is not present, it defaults to false.
RowShrink true|false;
If this option is set to true on each element in a row and there
is not enough vertical space, the row will be shrunk as necessary
to fit the available space. Note that a row may be shrunk even if
RowShrink is false; it simply indicates that aptitude should try
shrinking a particular row before shrinking other rows.
If this option is not present, it defaults to false.
Visible true|false;
If set to false, this display element will initially be hidden.
Presumably only useful in conjunction with PopUpDownKey and/or
PopUpDownLinked.
If this option is not present, it defaults to true.
Width width;
Specifies the width of the current display element.
Configuration file reference
Configuration file format
In its basic form, aptitude's configuration file is a list of options and
their values. Each line of the file should have the form "Option Value;":
for instance, the following line in the configuration file sets the option
Aptitude::Theme to "Dselect".
Aptitude::Theme "Dselect";
An option can "contain" other options if they are written in curly braces
between the option and the semicolon following it, like this:
Aptitude::UI {
Package-Status-Format "";
Package-Display-Format "";
};
An option that contains other options is sometimes called a group. In
fact, the double colons that appear in option names are actually a
shorthand way of indicating containment: the option
Aptitude::UI::Default-Grouping is contained in the group Aptitude::UI,
which itself is contained in the group Aptitude. Thus, if you wanted to,
you could set this option to "" as follows:
Aptitude {
UI {
Default-Grouping "";
};
};
For more information on the format of the configuration file, see the
manual page apt.conf(5).
Locations of configuration files
aptitude's configuration is read from the following sources, in order:
1. Configuration file options specified on the command-line.
2. The user's configuration file, ~/.aptitude/config. This file is
overwritten when the user modifies settings in the Options menu.
3. The system configuration file, /etc/apt/apt.conf.
4. The system configuration fragment files, /etc/apt/apt.conf.d/*.
5. The file specified by the APT_CONFIG environment variable (if any).
6. Default values stored in /usr/share/aptitude/aptitude-defaults.
7. Default values built into aptitude.
When an option is being checked, these sources are searched in order, and
the first one that provides a value for the option is used. For instance,
setting an option in /etc/apt/apt.conf will override aptitude's defaults
for that option, but will not override user settings in
~/.aptitude/config.
Available configuration options
The following configuration options are used by aptitude. Note that these
are not the only available configuration options; options used by the
underlying apt system are not listed here. See the manual pages apt(8) and
apt.conf(5) for information on apt options.
Option: Apt::AutoRemove::RecommendsImportant
Default: true
Description: If this option is true, then aptitude will not consider
packages to be unused (and thus will not automatically remove them) as
long as any installed package recommends them, even if
Apt::Install-Recommends is false. For more information, see the section
called "Managing automatically installed packages".
Option: Apt::AutoRemove::SuggestsImportant
Default: true
Description: If this option is true, then aptitude will not consider
packages to be unused (and thus will not automatically remove them) as
long as any installed package suggests them. For more information, see the
section called "Managing automatically installed packages".
Option: Apt::Get::List-Cleanup
Default: true
Description: A synonym for Apt::List-Cleanup. If either of these options
is set to false, aptitude will not delete old package list files after
downloading a new set of package lists.
Option: Apt::List-Cleanup
Default: true
Description: A synonym for Apt::Get::List-Cleanup. If either of these
options is set to false, aptitude will not delete old package list files
after downloading a new set of package lists.
Option: Apt::Install-Recommends
Default: true
Description: If this option is true and Aptitude::Auto-Install is true,
then whenever you mark a package for installation, aptitude will also mark
the packages it recommends for installation. Furthermore, if this option
is true, aptitude will not consider packages to be unused (and thus will
not automatically remove them) as long as any installed package reommends
them. For more information, see the section called "Managing automatically
installed packages" and the section called "Immediate dependency
resolution".
Option: Aptitude::Allow-Null-Upgrade
Default: false
Description: Normally, if you try to start an install run when no actions
will be performed, aptitude will print a warning and return to the package
list. If this option is true, aptitude will continue to the preview screen
whenever there are upgradable packages, rather than displaying a reminder
about the Actions -> Mark Upgradable (U) command.
Option: Aptitude::Always-Use-Safe-Resolver
Default: false
Description: If this option is true, aptitude's command-line actions will
always use a "safe" dependency resolver, as if --safe-resolver had been
passed on the command line.
Option: Aptitude::Autoclean-After-Update
Default: false
Description: If this option is true, aptitude will clean up obsolete files
(see Actions -> Clean obsolete files) every time you update the package
list.
Option: Aptitude::Auto-Fix-Broken
Default: true
Description: If this option is false, aptitude will ask for permission
before attempting to fix any broken packages.
Option: Aptitude::Auto-Install
Default: true
Description: If this option is true, aptitude will automatically attempt
to fulfill the dependencies of a package when you mark a package to be
installed or upgraded.
Option: Aptitude::Auto-Install-Remove-Ok
Default: false
Description: If this option is true, aptitude will automatically remove
conflicting packages when you mark a package to be installed or upgraded.
Normally these conflicts are flagged and you must handle them manually.
Option: Aptitude::Auto-Upgrade
Default: false
Description: If this option is true, aptitude will automatically flag all
upgradable packages for upgrade when the program starts, as if you had
issued the command Actions -> Mark Upgradable (U).
Option: Aptitude::CmdLine::Always-Prompt
Default: false
Description: In command-line mode, if this is set, aptitude will always
prompt before starting to install or remove packages, even if the prompt
would normally be skipped. This is equivalent to the -P command-line
option.
Option: Aptitude::CmdLine::Assume-Yes
Default: false
Description: In command-line mode, if this option is true, aptitude will
act as if the user had answered "yes" to every prompt, causing most
prompts to be skipped. This is equivalent to the -y command-line option.
Option: Aptitude::CmdLine::Disable-Columns
Default: false
Description: If this option is enabled, the results of command-line
searches (performed via aptitude search) will not be formatted into
fixed-width columns or truncated to the screen width. This is equivalent
to the --disable-columns command-line option.
Option: Aptitude::CmdLine::Download-Only
Default: false
Description: In command-line mode, if this option is true, aptitude will
download package files but not install them. This is equivalent to the -d
command-line option.
Option: Aptitude::CmdLine::Fix-Broken
Default: false
Description: In command-line mode, if this option is true, aptitude will
be more aggressive when attempting to fix the dependencies of broken
packages. This is equivalent to the -f command-line option.
Option: Aptitude::CmdLine::Versions-Group-By
Default: Set to auto, none, package, or source-package to control whether
and how the output of aptitude versions is grouped. Equivalent to the
command-line option --group-by (see its documentation for more description
of what the values mean).
Option: Aptitude::CmdLine::Ignore-Trust-Violations
Default: false
Description: In command-line mode, causes aptitude to ignore the
installation of untrusted packages. This is a synonym for
Apt::Get::AllowUnauthenticated.
Option: Aptitude::CmdLine::Package-Display-Format
Default: %c%a%M %p# - %d#
Description: This is a format string, as described in the section called
"Customizing how packages are displayed", which is used to display the
results of a command-line search. This is equivalent to the -F
command-line option.
Option: Aptitude::CmdLine::Package-Display-Width
Default:
Description: This option gives the width in characters for which
command-line search results should be formatted. If it is empty (the
default; ie, ""), search results will be formatted for the current
terminal size, or for an 80-column display if the terminal size cannot be
determined.
Option: Aptitude::CmdLine::Progress::Percent-On-Right
Default: false
Description: This option controls whether command-line progress indicators
display the percentage on the left-hand side of the screen, in the same
style as apt-get, or on the right-hand side (the default). This option
does not affect download progress indicators.
Option: Aptitude::CmdLine::Progress::Retain-Completed
Default: false
Description: If this value is false, then command-line progress indicators
will be deleted and overwritten once the task they represent is completed.
If it is true, then they will be left on the terminal. This option does
not affect download progress indicators.
Option: Aptitude::CmdLine::Request-Strictness
Default: 10000
Description: When run in command-line mode, if dependency problems are
encountered, aptitude will add this value to the problem resolver score of
each action that you explicitly request.
Option: Aptitude::CmdLine::Resolver-Debug
Default: false
Description: In command-line mode, if this option is true, aptitude will
print extremely verbose information while attempting to resolve broken
dependencies. As the name suggests, this option is primarily meant to aid
in debugging the problem resolver.
Option: Aptitude::CmdLine::Resolver-Dump
Default:
Description: In command-line mode, if it is necessary to resolve broken
dependencies and this option is set to the name of a writable file, the
resolver state will be dumped to this file before any calculations are
undertaken.
Option: Aptitude::CmdLine::Resolver-Show-Steps
Default: false
Description: If this option is true, then a dependency solution will be
displayed as a sequence of resolutions of individual dependencies; for
instance, "wesnoth depends upon wesnoth-data (= 1.2.4-1) -> installing
wesnoth-data 1.2.4-1 (unstable)". To toggle between the two display modes,
press o at the prompt "Accept this solution?".
Option: Aptitude::CmdLine::Show-Deps
Default: false
Description: In command-line mode, if this option is true, aptitude will
display a brief summary of the dependencies (if any) relating to a
package's state. This is equivalent to the -D command-line option.
Option: Aptitude::CmdLine::Show-Size-Changes
Default: false

Description: This option sets the default value of the command-line
argument --show-summary. See the documentation of --show-summary for a
list of the allowed values of this option and their meanings.
Option: Aptitude::CmdLine::Show-Versions
Default: false
Description: In command-line mode, if this option is true, aptitude will
display the version of a package that is being installed or removed. This
is equivalent to the -V command-line option.
Option: Aptitude::CmdLine::Show-Why
Default: false
Description: In command-line mode, if this option is true, aptitude will
display the manually installed packages that require each automatically
installed package, or the manually installed packages that cause a
conflict with each automatically removed package. This is equivalent to
the -W command-line option and displays the same information you can
access via aptitude why or by pressing i in a package list.
Option: Aptitude::CmdLine::Version-Display-Format
Default: %c%a%M %p# %t %i
Description: This is a format string, as described in the section called
"Customizing how packages are displayed", which is used to display the
output of aptitude versions. This is equivalent to the -F command-line
option.
Option: Aptitude::CmdLine::Versions-Show-Package-Names
Default: Set to always, auto, or never to control when package names are
displayed in the output of aptitude versions. Equivalent to the
command-line option --show-package-names (see its documentation for more
description of what the values mean).
Option: Aptitude::Safe-Resolver::Show-Resolver-Actions
Default: false
Description: If this option is enabled, then when the "safe" dependency
resolver has been activated via --safe-resolver or because the
command-line action is safe-upgrade, it will display a summary of the

Description: The maximum number of bytes of screenshot data that aptitude
will store in memory for screenshots that are not currently being
displayed. The default is four megabytes.
Option: Aptitude::CmdLine::Simulate
Default: false
Description: This option is deprecated; use Aptitude::Simulate instead. In
command-line mode, causes aptitude to just display the actions that would
be performed (rather than actually performing them); in the visual
interface, causes aptitude to start in read-only mode regardless of
whether you are root or not. This is equivalent to the -s command-line
option.
Option: Aptitude::CmdLine::Verbose
Default: 0
Description: This controls how verbose the command-line mode of aptitude
is. Every occurrence of the -v command-line option adds 1 to this value.
Option: Aptitude::CmdLine::Visual-Preview
Default: false
Description: If this option is true, aptitude will enter its visual
interface to display the preview of an installation run and to download
packages.
Option: Aptitude::Delete-Unused
Default: true
Description: If this option is true, automatically installed packages
which are no longer required will be automatically removed. For more
information, see the section called "Managing automatically installed
packages".
Option: Aptitude::Delete-Unused-Pattern
Default:
Description: Deprecated alias for Aptitude::Keep-Unused-Pattern. If
Aptitude::Keep-Unused-Pattern is unset or set to an empty string, the
value of this configuration option will override it. Otherwise,
Aptitude::Delete-Unused-Pattern is ignored.
Option: Aptitude::Display-Planned-Action
Default: true
Description: If this option is true, aptitude will display a preview
screen before actually carrying out the actions you have requested.
Option: Aptitude::Forget-New-On-Install
Default: false
Description: If this option is true, aptitude will clear the list of new
packages whenever you install, upgrade, or remove packages, as if you had
issued the command Actions -> Forget new packages (f).
Option: Aptitude::Forget-New-On-Update
Default: false
Description: If this option is true, aptitude will clear the list of new
packages whenever the package list is updated, as if you had issued the
command Actions -> Forget new packages (f).
Option: Aptitude::Get-Root-Command
Default: su:/bin/su
Description: This option sets the external command that aptitude will use
to switch to the root user (see the section called "Becoming root"). It
has the form protocol:command. protocol must be either su or sudo; it
determines how aptitude invokes the program when it wants to gain root
privileges. If protocol is su, then "command -c arguments" is used to
become root; otherwise, aptitude uses "command arguments". The first word
in command is the name of the program that should be invoked; remaining
words are treated as arguments to that program.
Option: Aptitude::Ignore-Old-Tmp
Default: false
Description: Old versions of aptitude created a directory ~/.aptitude/.tmp
which is no longer necessary. If the directory exists and
Aptitude::Ignore-Old-Tmp is true, aptitude will ask you whether to remove
this directory. This option is automatically set to true after you reply.
On the other hand, if the directory does not exist, this option is set to
false so that you will be notified if it reappears.
Option: Aptitude::Ignore-Recommends-Important
Default: false
Description: In previous versions of aptitude, the setting
Aptitude::Recommends-Important caused recommendations to be installed
automatically, the same way that Apt::Install-Recommends does today. If
this option is set to false and Aptitude::Recommends-Important is also set
to false, aptitude will set Apt::Install-Recommends to false and set
Aptitude::Ignore-Recommends-Important to true on startup.
Option: Aptitude::Keep-Recommends
Default: false
Description: This is an obsolete option; use
Apt::AutoRemove::RecommendsImportant instead. Setting this option to true
has the same effect as setting Apt::AutoRemove::RecommendsImportant to
true.
Option: Aptitude::Keep-Suggests
Default: false
Description: This is an obsolete option; use
Apt::AutoRemove::SuggestsImportant instead. Setting this option to true
has the same effect as setting Apt::AutoRemove::SuggestsImportant to true.
Option: Aptitude::Keep-Unused-Pattern
Default:
Description: If Aptitude::Delete-Unused is true, only unused packages
which do not match this pattern (see the section called "Search patterns")
will be removed. If this option is set to an empty string (the default),
all unused packages will be removed.
Option: Aptitude::LockFile
Default: /var/lock/aptitude
Description: A file that will be fcntl-locked to ensure that at most one
aptitude process can modify the cache at once. In normal circumstances,
you should never need to modify this; it may be useful for debugging.
Note: if aptitude complains that it cannot acquire a lock, this is not
because the lock file needs to be deleted. fcntl locks are managed by the
kernel and will be destroyed when the program holding them terminates;
failure to acquire the lock means that another running program is using
it!
Option: Aptitude::Log
Default: /var/log/aptitude
Description: If this is set to a nonempty string, aptitude will log the
package installations, removals, and upgrades that it performs. If the
value of Aptitude::Log begins with a pipe character (ie, "|"), the
remainder of its value is used as the name of a command into which the log
will be piped: for instance, |mail -s 'Aptitude install run' root will
cause the log to be emailed to root. To log to multiple files or commands,
you may set this option to a list of log targets.
Option: Aptitude::Logging::File
Default:
Description: If this is set to a nonempty string, aptitude will write
logging messages to it; setting it to "-" causes logging messages to be
printed to standard output. This differs from the setting Aptitude::Log:
that file is used to log installations and removals, whereas this file is
used to log program events, errors, and debugging messages (if enabled).
This option is equivalent to the command-line argument --log-file. See
also Aptitude::Logging::Levels.
Option: Aptitude::Logging::Levels
Default: (empty)
Description: This option is a group whose members control which log
messages are written. Each entry is either "level", to set the global log
level (the log level of the root logger) to the given level, or
"category:level", where category is the category of messages to modify
(such as aptitude.resolver.hints.match) and level is the lowest log level
of messages in that category that should be displayed. Valid log levels
are "fatal", "error", "warn", "info", "debug", and "trace". The
command-line option --log-level can be used to set or override any log
level.
Option: Aptitude::Parse-Description-Bullets
Default: true
Description: If this option is enabled, aptitude will attempt to
automatically detect bulleted lists in package descriptions. This will
generally improve how descriptions are displayed, but it is not entirely
backwards-compatible; some descriptions might be formatted less
attractively when this option is true than when it is false.
Option: Aptitude::Pkg-Display-Limit
Default:
Description: The default filter applied to the package list; see the
section called "Search patterns" for details about its format.
Option: Aptitude::ProblemResolver::Allow-Break-Holds
Default: false
Description: If this option is set to true, the problem resolver will
consider breaking package holds or installing forbidden versions in order
to resolve a dependency. If it is set to false, these actions will be
rejected by default, although you can always enable them manually (see the
section called "Resolving Dependencies Interactively").
Option: Aptitude::ProblemResolver::BreakHoldScore
Default: -300
Description: How much to reward or penalize solutions that change the
state of a held package or install a forbidden version. Note that unless
Aptitude::ProblemResolver::Allow-Break-Holds is set to true, the resolver
will never break a hold or install a forbidden version unless it has
explicit permission from the user.
Option: Aptitude::ProblemResolver::Break-Hold-Level
Default: 50000
Description: The safety cost assigned to actions that break a hold set by
the user (by upgrading a held package or by installing a forbidden version
of a package). See the section called "Safety costs" for a description of
safety costs.
Option: Aptitude::ProblemResolver::BrokenScore
Default: -100
Description: How much to reward or penalize prospective solutions based on
the number of dependencies they break. For each dependency broken by a
possible solution, this many points are added to its score; typically this
should be a negative value.
Option: Aptitude::ProblemResolver::DefaultResolutionScore
Default: 400
Description: How much to reward or penalize prospective solutions based on
how many "default" resolutions for currently unsatisfied dependencies they
install. The default resolution is the resolution that "apt-get install"
or the "immediate dependency resolver" would pick. The score is only
applied for dependencies and recommendations whose targets are not
currently installed.
Option: Aptitude::ProblemResolver::Discard-Null-Solution
Default: true
Description: If this option is true, aptitude will never suggest
cancelling all of your proposed actions in order to resolve a dependency
problem.
Option: Aptitude::ProblemResolver::EssentialRemoveScore
Default: -100000
Description: How much to reward or penalize solutions that remove an
Essential package.
Option: Aptitude::ProblemResolver::Remove-Essential-Level
Default: 60000
Description: The safety cost assigned to actions that remove an Essential
package. See the section called "Safety costs" for a description of safety
costs.
Option: Aptitude::ProblemResolver::ExtraScore
Default: -1
Description: Any version of a package whose Priority is "extra" will have
this many points added to its score.
Option: Aptitude::ProblemResolver::FullReplacementScore
Default: 500
Description: Removing a package and installing another package that fully
replaces it (i.e., conflicts with it, replaces it, and provides it) is
assigned this score.
Option: Aptitude::ProblemResolver::FutureHorizon
Default: 50
Description: How many "steps" the resolver should run after finding the
first solution. Although aptitude attempts to generate better solutions
before worse solutions, sometimes it is unable to do so; this setting
causes the resolver to briefly continue searching for a better solution
before displaying its results, rather than stopping immediately after it
finds the first solution.
Option: Aptitude::ProblemResolver::Hints
Default: (empty)
Description: This option is a group whose members are used to configure
the problem resolver. Each item in the group is a string describing an
action that should be applied to one or more packages. The syntax for each
hint, and the effect that hints have, may be found in the section called
"Configuring resolver hints".
Option: Aptitude::ProblemResolver::ImportantScore
Default: 5
Description: Any version of a package whose Priority is "important" will
have this many points added to its score.
Option: Aptitude::ProblemResolver::Infinity
Default: 1000000
Description: A "maximum" score for potential solutions. If a set of
actions has a score worse than -Infinity, it will be discarded
immediately.
Option: Aptitude::ProblemResolver::InstallScore
Default: -20
Description: How much weight the problem resolver should give to
installing a package, if the package is not already going to be installed.
Option: Aptitude::ProblemResolver::Keep-All-Level
Default: 20000
Description: The safety cost assigned to the single solution that cancels
all of the actions selected by the user. See the section called "Safety
costs" for a description of safety costs.
Option: Aptitude::ProblemResolver::KeepScore
Default: 0
Description: How much weight the problem resolver should give to keeping a
package in its current state, if that package is not already going to be
kept in its current state.
Option: Aptitude::ProblemResolver::NonDefaultScore
Default: -40
Description: How much weight the problem resolver should give to
installing a non-default version of the package (one that is not the
current version and not the "candidate version").
Option: Aptitude::ProblemResolver::Non-Default-Level
Default: 50000
Description: The safety cost assigned to actions that install non-default
versions of a package. For instance, if version 5 of a package is
installed, versions 6, 7, and 8 are available, and version 7 is the
default version, then versions 6 and 8 will be given a safety cost that is
at least this high. See the section called "Safety costs" for a
description of safety costs.
Option: Aptitude::ProblemResolver::OptionalScore
Default: 1
Description: Any version of a package whose Priority is "optional" will
have this many points added to its score.
Option: Aptitude::ProblemResolver::PreserveAutoScore
Default: 0
Description: How much weight the problem resolver should give to
preserving automatic installations or removals.
Option: Aptitude::ProblemResolver::PreserveManualScore
Default: 60
Description: How much weight the problem resolver should give to
preserving explicit user selections.
Option: Aptitude::ProblemResolver::RemoveScore
Default: -300
Description: How much weight the problem resolver should give to removing
a package (if it is not already marked for removal).
Option: Aptitude::ProblemResolver::Remove-Level
Default: 10000
Description: The safety cost assigned to actions that remove a package.
See the section called "Safety costs" for a description of safety costs.
Option: Aptitude::ProblemResolver::RequiredScore
Default: 4
Description: Any version of a package whose Priority is "required" will
have this many points added to its score.
Option: Aptitude::ProblemResolver::ResolutionScore
Default: 50
Description: In addition to all other scoring factors, proposed solutions
that actually resolve all unsatisfied dependencies are awarded this many
extra points.
Option: Aptitude::ProblemResolver::Safe-Level
Default: 10000
Description: The safety cost assigned to actions that install the default
version of a package, upgrade a package to its default version, or cancel
installing or upgrading a package. Solutions assigned this cost could be
generated by aptitude safe-upgrade. See the section called "Safety costs"
for a description of safety costs.
Option: Aptitude::ProblemResolver::SolutionCost
Default: safety,priority
Description: Describes how to determine the cost of a solution. See the
section called "Costs in the interactive dependency resolver" for a
description of what solution costs are, what they do, and the syntax used
to specify them. If the cost cannot be parsed, an error is issued and the
default cost is used instead.
Option: Aptitude::ProblemResolver::StandardScore
Default: 3
Description: Any version of a package whose Priority is "standard" will
have this many points added to its score.
Option: Aptitude::ProblemResolver::StepLimit
Default: 5000
Description: The maximum number of "steps" which should be performed by
the problem resolver on each attempt to find a solution to a dependency
problem. Decreasing this number will make aptitude "give up" sooner;
increasing it will permit the search for a solution to consume much more
time and memory before it is aborted. Setting StepLimit to 0 will disable
the problem resolver entirely. The default value is large enough to
accomodate commonly encountered situations, while preventing aptitude from
"blowing up" if an overly complicated problem is encountered. (note: this
applies only to command-line searches; in the visual interface, the
resolver will continue working until it reaches a solution)
Option: Aptitude::ProblemResolver::StepScore
Default: 70
Description: How much to reward or penalize prospective solutions based on
their length. For each action performed by a solution, this many points
are added to its score. The larger this value is, the more the resolver
tends to stick with its first choice rather than considering alternatives;
this will cause it to produce a solution more quickly, but the solution
might be of slightly lower quality than it would otherwise be.
Option: Aptitude::ProblemResolver::Trace-Directory
Default:
Description: If this value is set, then each time the problem resolver
produces a solution, a stripped-down version of the package state
sufficient to reproduce that solution is written to the given file. If
Aptitude::ProblemResolver::Trace-File is also set, the same information
will also be written to the trace file. Trace directories are more
transparent than trace files, and are more suitable for, e.g., including
in source trees as test cases.
Option: Aptitude::ProblemResolver::Trace-File
Default:
Description: If this value is set, then each time the problem resolver
produces a solution, a stripped-down version of the package state
sufficient to reproduce that solution is written to the given file. If
Aptitude::ProblemResolver::Trace-Directory is also set, the same
information will also be written to the trace directory. A trace file is
simply a compressed archive of a trace directory; it will take less space
than the trace directory and is suitable for transmission over a network.
Option: Aptitude::ProblemResolver::UndoFullReplacementScore
Default: -500
Description: Installing a package and removing another package that fully
replaces it (i.e., conflicts with it, replaces it, and provides it) is
assigned this score.
Option: Aptitude::ProblemResolver::UnfixedSoftScore
Default: -200
Description: How much to reward or penalize leaving a Recommends
relationship unresolved. This should typically be less than RemoveScore,
or aptitude will tend to remove packages rather than leaving their
Recommendations unfixed. See the section called "Resolving Dependencies
Interactively" for details.
Option: Aptitude::ProblemResolver::UpgradeScore
Default: 0
Description: How much weight the problem resolver should give to upgrading
(or downgrading) a package to its candidate version, if the package was
not already going to be upgraded.
Option: Aptitude::Purge-Unused
Default: false
Description: If this option is true and Aptitude::Delete-Unused is also
true, then packages which are unused will be purged from the system,
removing their configuration files and perhaps other important data. For
more information about which packages are considered to be "unused", see
the section called "Managing automatically installed packages". THIS
OPTION CAN CAUSE DATA LOSS! DO NOT ENABLE IT UNLESS YOU KNOW WHAT YOU ARE
DOING!
Option: Aptitude::Recommends-Important
Default: true
Description: This is an obsolete configuration option that has been
superseded by Apt::Install-Recommends. On startup, aptitude will copy
Aptitude::Recommends-Important (if it exists) to Apt::Install-Recommends
and then clear Aptitude::Recommends-Important in your user configuration
file.
Option: Aptitude::Safe-Resolver::No-New-Installs
Default: false
Description: If this option is true, then when the "safe" dependency
resolver has been activated via --safe-resolver or by using the
safe-upgrade command-line action, the resolver will not be allowed to
install packages that are not currently installed.
Option: Aptitude::Safe-Resolver::No-New-Upgrades
Default: false
Description: If this option is enabled, then when the "safe" dependency
resolver has been activated via --safe-resolver or by using the
safe-upgrade command-line action, the resolver will not be allowed to
resolve dependencies by upgrading packages.
Option: Aptitude::Sections::Descriptions
Default: See $prefix/share/aptitude/section-descriptions
Description: This option is a group whose members define the descriptions
displayed for each section when using the "section" package hierarchy
grouping policy. Descriptions are assigned to section trees based on the
last component of the name: for instance, a member of this group named
"games" will be used to describe the Sections "games", "non-free/games",
and "non-free/desktop/games". Within the text of section descriptions, the
string "\n" will be replaced by a line-break, and the string "''" will be
replaced by a double-quote character.
Option: Aptitude::Sections::Top-Sections
Default: "main"; "contrib"; "non-free"; "non-US";
Description: A configuration group whose elements are the names of the
top-level archive sections. The "topdir", "subdir", and "subdirs" grouping
policies use this list to interpret Section fields: if the first path
element of a package's Section is not contained in this list, or if its
Section has only one element, then the package will be grouped using the
first member of this list as its first path element. For example, if the
first member of Top-Sections is "main", then a package whose Section is
"games/arcade" will be treated as if its Section field were
"main/games/arcade".
Option: Aptitude::Simulate
Default: false
Description: In command-line mode, causes aptitude to just display the
actions that would be performed (rather than actually performing them); in
the visual interface, causes aptitude to start in read-only mode
regardless of whether you are root or not. This is equivalent to the -s
command-line option.
Option: Aptitude::Spin-Interval
Default: 500
Description: The number of milliseconds to delay in between updating the
"spinner" that appears while the problem resolver is running.
Option: Aptitude::Suggests-Important
Default: false
Description: This is an obsolete option; use
Apt::AutoRemove::SuggestsImportant instead. Setting this option to true
has the same effect as setting Apt::AutoRemove::SuggestsImportant to true.
Option: Aptitude::Suppress-Read-Only-Warning
Default: false
Description: If this option is false, aptitude will display a warning the
first time that you attempt to modify package states while aptitude is in
read-only mode.
Option: Aptitude::Theme
Default:
Description: The theme that aptitude should use; see the section called
"Themes" for more information.
Option: Aptitude::Track-Dselect-State
Default: true
Description: If this option is set to true, aptitude will attempt to
detect when a change to a package's state has been made using dselect or
dpkg: for instance, if you remove a package using dpkg, aptitude will not
try to reinstall it. Note that this may be somewhat buggy.
Option: Aptitude::UI::Advance-On-Action
Default: false
Description: If this option is set to true, changing a package's state
(for instance, marking it for installation) will cause aptitude to advance
the highlight to the next package in the current group.
Option: Aptitude::UI::Auto-Show-Reasons
Default: true
Description: If this option is set to true, selecting a package which is
broken or which appears to be causing other packages to be broken will
cause the information area to automatically display some reasons why the
breakage might be occuring.
Option: Aptitude::UI::Default-Grouping
Default:
filter(missing),status,section(subdirs,passthrough),section(topdir)
Description: Sets the default grouping policy used for package lists. See
the section called "Customizing the package hierarchy" for additional
information on grouping policies.
Option: Aptitude::UI::Default-Package-View
Default:
Description: This option is a group whose members define the default
layout of aptitude's display. See the section called "Customizing the
display layout" for more information.
Option: Aptitude::UI::Default-Preview-Grouping
Default: action
Description: Sets the default grouping policy used for preview screens.
See the section called "Customizing the package hierarchy" for additional
information on grouping policies.
Option: Aptitude::UI::Default-Sorting
Default: name
Description: The default sorting policy of package views. See the section
called "Customizing how packages are sorted" for more information.
Option: Aptitude::UI::Description-Visible-By-Default
Default: true
Description: When a package list is first displayed, the information area
(which typically contains the long description of the current package)
will be visible if this option is true and hidden if it is false.
Option: Aptitude::UI::Exit-On-Last-Close
Default: true
Description: If this option is true, closing all the active views will
quit aptitude; otherwise, aptitude will not exit until you issue the
command Actions -> Quit (Q). See the section called "Working with multiple
views" for more information.
Option: Aptitude::UI::Fill-Text
Default: false
Description: If this option is true, aptitude will format descriptions so
that each line is exactly the width of the screen.
Option: Aptitude::UI::Flat-View-As-First-View
Default: false
Description: If this option is true, aptitude will display a flat view on
startup instead of the default view.
Option: Aptitude::UI::HelpBar
Default: true
Description: If this option is true, a line of information about important
keystrokes will be displayed at the top of the screen.
Option: Aptitude::UI::Incremental-Search
Default: true
Description: If this option is true, aptitude will perform "incremental"
searches: as you type the search pattern, it will search for the next
package matching what you have typed so far.
Option: Aptitude::UI::InfoAreaTabs
Default: false
Description: If this option is true, aptitude will display tabs at the top
of the information area (the pane at the bottom of the screen) describing
the different modes the area can be set to.
Option: Aptitude::UI::Keybindings
Default:
Description: This is a group whose members define the connections between
keystrokes and commands in aptitude. For more information, see the section
called "Customizing keybindings".
Option: Aptitude::UI::Menubar-Autohide
Default: false
Description: If this option is set to true, the menu bar will be hidden
while it is not in use.
Option: Aptitude::UI::Minibuf-Download-Bar
Default: false
Description: If this option is set to true, aptitude will use a less
obtrusive mechanism to display the progress of downloads: a bar at the
bottom of the screen will appear which displays the current download
status. While the download is active, pressing q will abort it.
Option: Aptitude::UI::Minibuf-Prompts
Default: false
Description: If this option is true, some prompts (such as yes/no and
multiple-choice prompts) will be displayed at the bottom of the screen
instead of in dialog boxes.
Option: Aptitude::UI::New-Package-Commands
Default: true
Description: If this option is set to false, commands such as Package ->
Install (+) will have the same deprecated behavior that they did in
antique versions of aptitude.
Option: Aptitude::UI::Package-Display-Format
Default: %c%a%M %p %Z %v %V
Description: This option controls the format string used to display
packages in package lists. For more information on format strings, see the
section called "Customizing how packages are displayed".
Option: Aptitude::UI::Package-Header-Format
Default: %N %n #%B %u %o
Description: This option controls the format string used to display the
header line of package lists (ie, the line that appears between the
package list and the menu bar). For more information on format strings,
see the section called "Customizing how packages are displayed".
Option: Aptitude::UI::Package-Status-Format
Default: %d
Description: This option controls the format string used to display the
status line of package lists (ie, the line that appears between the
package list and the information area). For more information on format
strings, see the section called "Customizing how packages are displayed".
Option: Aptitude::UI::Pause-After-Download
Default: OnlyIfError
Description: If this option is true, aptitude will display a message after
it finishes downloading packages, asking you if you want to continue with
the installation. If it is OnlyIfError, a message will only be displayed
if a download failed. Otherwise, if the option is set to false, aptitude
will immediately proceed to the next screen after completing a download.
Option: Aptitude::UI::Preview-Limit
Default:
Description: The default filter applied to the preview screen; see the
section called "Search patterns" for details about its format.
Option: Aptitude::UI::Prompt-On-Exit
Default: true
Description: If this option is true, aptitude will display a confirmation
prompt before shutting down.
Option: Aptitude::UI::Styles
Default:
Description: This is a configuration group whose contents define what
textual styles aptitude uses to display information. For more information,
see the section called "Customizing text colors and styles".
Option: Aptitude::UI::ViewTabs
Default: true
Description: If this option is set to false, aptitude will not display
"tabs" describing the currently active views at the top of the screen.
Option: Aptitude::Warn-Not-Root
Default: true
Description: If this option is true, aptitude will detect when you need
root privileges to do something, and ask you whether you want to switch to
the root account if you aren't root already. See the section called
"Becoming root" for more information.
Option: DebTags::Vocabulary
Default: /usr/share/debtags/vocabulary
Description: The location of the debtags vocabulary file; used to load in
the package tag metadata.
Option: Dir::Aptitude::state
Default: /var/lib/aptitude
Description: The directory in which aptitude's persistent state
information is stored.
Option: Quiet
Default: 0
Description: This controls the quietness of the command-line mode. Setting
it to a higher value will disable more progress indicators.
Themes
A theme in aptitude is simply a collection of settings that "go together".
Themes work by overriding the default values of options: if an option is
not set in the system configuration file or in your personal configuration
file, aptitude will use the setting from the current theme, if one is
available, before using the standard default value.
A theme is simply a named group under Aptitude::Themes; each configuration
option contained in the group will override the corresponding option in
the global configuration. For instance, if the Dselect theme is selected,
the option Aptitude::Themes::Dselect::Aptitude::UI::Package-Display-Format
will override the default value of the option
Aptitude::UI::Package-Display-Format.
To select a theme, set the configuration option Aptitude::Theme to the
name of the theme; for instance,
Aptitude::Theme Vertical-Split;
The following themes are shipped with aptitude in
/usr/share/aptitude/aptitude-defaults:
Dselect
This theme makes aptitude look and behave more like the legacy
dselect package manager:

Playing Minesweeper
In case you get tired of installing and removing packages, aptitude
includes a version of the classic game "Minesweeper". To start it, select
Actions -> Play Minesweeper; the initial Minesweeper board will appear:

Within the rectangle that appears on the screen are hidden ten mines. Your
goal is to determine, through intuition, logic, and luck, where those
mines are, without setting any of them off! To do this, you must uncover
all the squares that do not contain mines; in doing so, you will learn
important information regarding which squares do contain mines. Beware,
however: uncovering a square that contains a mine will set it off, ending
your game immediately!
To uncover a square (and find out whether a mine is hidden there), select
the square with the arrow keys and press Enter:

possible to uncover this square, even accidentally, until the flag is
removed (by pressing f again). Once you have placed flags on all the mines
that are next to a square (for instance, the squares labelled 1 next to
the flag above), you can "sweep" around the square. This is just a
convenient shortcut to uncover all the squares next to it (except those
containing a flag, of course). For instance, sweeping around the 1 above:

Luckily (or was it luck?), my guess about the location of that mine was
correct. If I had been wrong, I would have lost immediately:

--------------------------------------------------------------------------
^[7] I am pleased to say that the number of requests of this sort fell off
precipitously following the initial publication of this Guide. It would be
a happy occurrence if there was a connection between the two events.
^[8] This is sometimes referred to as an "install run", even though you
might be upgrading or removing packages in addition to installing them.
^[9] As noted above, it does not indicate that the packages in the archive
are secure, or even non-malicious; it merely shows that they are genuine.
^[10] More precisely: they will be removed when there is no path via
Depends, PreDepends, or Recommends to them from a manually installed
package. If Apt::AutoRemove::SuggestsImportant is true, a Suggests
relationship is also enough to keep a package installed.
^[11] Or when immediate resolution is disabled.
^[12] The package with the highest dpkg priority, not the package with the
highest apt pin priority.
^[13] This limit was imposed because more complex cost structures could
make it difficult to optimize the resolver. Future versions of the program
might remove some of the restrictions if they turn out to be unnecessary.
^[14] aptitude will only treat the comma as special if there is a second
argument, so (for instance) "?name(apt,itude)" searches for the string
"apt,itude" in the Name field of packages.
While this behavior is well-defined, it may be surprising; I recommend
using quoted strings for any pattern that contains characters that could
have a special meaning.
^[15] Characters with a special meaning include: "+", "-", ".", "(", ")",
"|", "[", "]", "^", "$", and "?". Note that some of these are also
aptitude metacharacters, so if you want to type (for instance) a literal
"|", it must be double-escaped: "?description(\~|)" will match packages
whose description contains a vertical bar character ("|").
^[16] The backslash escapes \\, \n, and \t are also available.
^[17] Astute readers will note that this is essentially a way to
explicitly name the variable in the l-terms corresponding to the term. A
typical term would have the form "l x . name-equals(x, pattern)"; giving
this an explicit target makes x visible in the search language.
^[18] This is provided largely for symmetry with ?true.
^[19] Currently tagging is not supported; this escape is for future use.
^[20] On some terminals, a "yellow" background will actually come out
brown.

3.1. How can I find exactly one package by name?
As mentioned in the section called "Search patterns", when you search
for a package by name, the text you enter is actually a regular
expression. Thus, the search pattern "^name$" will match only a
package named name.
For instance, you can find apt (but not aptitude or synaptic) by
entering ^apt$; you can find g++ (but not g++-2.95 or g++-3.0) by
entering ^g\+\+$.
3.2. How can I find broken packages?
Use the command Search -> Find Broken (b).
3.3. I want to select text, why doesn't aptitude let me disable the mouse?
Normally, you cannot select text in an xterm while a program running
in that terminal (such as aptitude) is using the mouse. However, you
can override this behavior and perform a selection by holding the
Shift key down while you click on the terminal.

aptitude help
Description
aptitude is a text-based interface to the Debian GNU/Linux package system.
It allows the user to view the list of packages and to perform package
management tasks such as installing, upgrading, and removing packages.
Actions may be performed from a visual interface or from the command-line.
Command-line actions
The first argument which does not begin with a hyphen ("-") is considered
to be an action that the program should perform. If an action is not
specified on the command-line, aptitude will start up in visual mode.
The following actions are available:
install
Install one or more packages. The packages should be listed after
the "install" command; if a package name contains a tilde
character ("~") or a question mark ("?"), it will be treated as a
search pattern and every package matching the pattern will be
installed (see the section "Search Patterns" in the aptitude
reference manual).
To select a particular version of the package, append "=version"
to the package name: for instance, "aptitude install apt=0.3.1".
Similarly, to select a package from a particular archive, append
"/archive" to the package name: for instance, "aptitude install
apt/experimental". You cannot specify both an archive and a
version for a package.
Not every package listed on the command line has to be installed;
you can tell aptitude to do something different with a package by
appending an "override specifier" to the name of the package. For
example, aptitude remove wesnoth+ will install wesnoth, not remove
it. The following override specifiers are available:
package+
Install package.
package+M
Install package and immediately mark it as
automatically installed (note that if nothing depends
on package, this will cause it to be immediately
removed).
package-
Remove package.
package_
Purge package: remove it and all its associated
configuration and data files.
package=
Place package on hold: cancel any active
installation, upgrade, or removal, and prevent this
package from being automatically upgraded in the
future.
package:
Keep package at its current version: cancel any
installation, removal, or upgrade. Unlike "hold"
(above) this does not prevent automatic upgrades in
the future.
package&M
Mark package as having been automatically installed.
package&m
Mark package as having been manually installed.
As a special case, "install" with no arguments will act on any
stored/pending actions.
[Note] Note
Once you enter Y at the final confirmation prompt, the
"install" command will modify aptitude's stored information
about what actions to perform. Therefore, if you issue
(e.g.) the command "aptitude install foo bar" and then
abort the installation once aptitude has started
downloading and installing packages, you will need to run
"aptitude remove foo bar" to cancel that order.
remove, purge, hold, unhold, keep, reinstall
These commands are the same as "install", but apply the named
action to all packages given on the command line for which it is
not overridden. The difference between hold and keep is that hold
will cause a package to be ignored by future safe-upgrade or
full-upgrade commands, while keep merely cancels any scheduled
actions on the package. unhold will allow a package to be upgraded
by future safe-upgrade or full-upgrade commands, without otherwise
altering its state.
For instance, "aptitude remove '~ndeity'" will remove all packages
whose name contains "deity".
markauto, unmarkauto
Mark packages as automatically installed or manually installed,
respectively. Packages are specified in exactly the same way as
for the "install" command. For instance, "aptitude markauto
'~slibs'" will mark all packages in the "libs" section as having
been automatically installed.
For more information on automatically installed packages, see the
section "Managing Automatically Installed Packages" in the
aptitude reference manual.
build-depends, build-dep
Satisfy the build-dependencies of a package. Each package name may
be a source package, in which case the build dependencies of that
source package are installed; otherwise, binary packages are found
in the same way as for the "install" command, and the
build-dependencies of the source packages that build those binary
packages are satisfied.
If the command-line parameter --arch-only is present, only
architecture-dependent build dependencies (i.e., not
Build-Depends-Indep or Build-Conflicts-Indep) will be obeyed.
forbid-version
Forbid a package from being upgraded to a particular version. This
will prevent aptitude from automatically upgrading to this
version, but will allow automatic upgrades to future versions. By
default, aptitude will select the version to which the package
would normally be upgraded; you may override this selection by
appending "=version" to the package name: for instance, "aptitude
forbid-version vim=1.2.3.broken-4".
This command is useful for avoiding broken versions of packages
without having to set and clear manual holds. If you decide you
really want the forbidden version after all, "aptitude install
package" will remove the ban.
update
Updates the list of available packages from the apt sources (this
is equivalent to "apt-get update")
safe-upgrade
Upgrades installed packages to their most recent version.
Installed packages will not be removed unless they are unused (see
the section "Managing Automatically Installed Packages" in the
aptitude reference manual). Packages which are not currently
installed may be installed to resolve dependencies unless the
--no-new-installs command-line option is supplied.
If no packages are listed on the command line, aptitude will
attempt to upgrade every package that can be upgraded. Otherwise,
aptitude will attempt to upgrade only the packages which it is
instructed to upgrade. The packages can be extended with suffixes
in the same manner as arguments to aptitude install, so you can
also give additional instructions to aptitude here; for instance,
aptitude safe-upgrade bash dash- will attempt to upgrade the bash
package and remove the dash package.
It is sometimes necessary to remove one package in order to
upgrade another; this command is not able to upgrade packages in
such situations. Use the full-upgrade command to upgrade as many
packages as possible.
full-upgrade
Upgrades installed packages to their most recent version, removing
or installing packages as necessary. This command is less
conservative than safe-upgrade and thus more likely to perform
unwanted actions. However, it is capable of upgrading packages
that safe-upgrade cannot upgrade.
If no packages are listed on the command line, aptitude will
attempt to upgrade every package that can be upgraded. Otherwise,
aptitude will attempt to upgrade only the packages which it is
instructed to upgrade. The packages can be extended with suffixes
in the same manner as arguments to aptitude install, so you can
also give additional instructions to aptitude here; for instance,
aptitude full-upgrade bash dash- will attempt to upgrade the bash
package and remove the dash package.
[Note] Note
This command was originally named dist-upgrade for
historical reasons, and aptitude still recognizes
dist-upgrade as a synonym for full-upgrade.
keep-all
Cancels all scheduled actions on all packages; any packages whose
sticky state indicates an installation, removal, or upgrade will
have this sticky state cleared.
forget-new
Forgets all internal information about what packages are "new"
(equivalent to pressing "f" when in visual mode).
search
Searches for packages matching one of the patterns supplied on the
command line. All packages which match any of the given patterns
will be displayed; for instance, "aptitude search '~N' edit" will
list all "new" packages and all packages whose name contains
"edit". For more information on search patterns, see the section
"Search Patterns" in the aptitude reference manual.
[Note] Note
In the example above, "aptitude search '~N' edit" has two
arguments after search and thus is searching for two
patterns: "~N" and "edit". As described in the search
pattern reference, a single pattern composed of two
sub-patterns separated by a space (such as "~N edit")
matches only if both patterns match. Thus, the command
"aptitude search '~N edit'" will only show "new" packages
whose name contains "edit".
Unless you pass the -F option, the output of aptitude search will
look something like this:
i apt - Advanced front-end for dpkg
pi apt-build - frontend to apt to build, optimize and in
cp apt-file - APT package searching utility -- command-
ihA raptor-utils - Raptor RDF Parser utilities
Each search result is listed on a separate line. The first
character of each line indicates the current state of the package:
the most common states are p, meaning that no trace of the package
exists on the system, c, meaning that the package was deleted but
its configuration files remain on the system, i, meaning that the
package is installed, and v, meaning that the package is virtual.
The second character indicates the stored action (if any;
otherwise a blank space is displayed) to be performed on the
package, with the most common actions being i, meaning that the
package will be installed, d, meaning that the package will be
deleted, and p, meaning that the package and its configuration
files will be removed. If the third character is A, the package
was automatically installed.
For a complete list of the possible state and action flags, see
the section "Accessing Package Information" in the aptitude
reference guide. To customize the output of search, see the
command-line options -F and --sort.
show
Displays detailed information about one or more packages. If a
package name contains a tilde character ("~") or a question mark
("?"), it will be treated as a search pattern and all matching
packages will be displayed (see the section "Search Patterns" in
the aptitude reference manual).
If the verbosity level is 1 or greater (i.e., at least one -v is
present on the command-line), information about all versions of
the package is displayed. Otherwise, information about the
"candidate version" (the version that "aptitude install" would
download) is displayed.
You can display information about a different version of the
package by appending =version to the package name; you can display
the version from a particular archive or release by appending
/archive or /release to the package name: for instance, /unstable
or /sid. If either of these is present, then only the version you
request will be displayed, regardless of the verbosity level.
If the verbosity level is 1 or greater, the package's
architecture, compressed size, filename, and md5sum fields will be
displayed. If the verbosity level is 2 or greater, the select
version or versions will be displayed once for each archive in
which they are found.
versions
Displays the versions of the packages listed on the command-line.
$ aptitude versions wesnoth
p 1:1.4.5-1 100
p 1:1.6.5-1 unstable 500
p 1:1.7.14-1 experimental 1
Each version is listed on a separate line. The leftmost three
characters indicate the current state, planned state (if any), and
whether the package was automatically installed; for more
information on their meanings, see the documentation of aptitude
search. To the right of the version number you can find the
releases from which the version is available, and the pin priority
of the version.
If a package name contains a tilde character ("~") or a question
mark ("?"), it will be treated as a search pattern and all
matching versions will be displayed (see the section "Search
Patterns" in the aptitude reference manual). This means that, for
instance, aptitude versions '~i' will display all the versions
that are currently installed on the system and nothing else, not
even other versions of the same packages.
$ aptitude versions '~nexim4-daemon-light'
Package exim4-daemon-light:
i 4.71-3 100
p 4.71-4 unstable 500
Package exim4-daemon-light-dbg:
p 4.71-4 unstable 500
If the input is a search pattern, or if more than one package's
versions are to be displayed, aptitude will automatically group
the output by package, as shown above. You can disable this via
--group-by=none, in which case aptitude will display a single list
of all the versions that were found and automatically include the
package name in each output line:
$ aptitude versions --group-by=none '~nexim4-daemon-light'
i exim4-daemon-light 4.71-3 100
p exim4-daemon-light 4.71-4 unstable 500
p exim4-daemon-light-dbg 4.71-4 unstable 500
To disable the package name, pass --show-package-names=never:
$ aptitude versions --show-package-names=never --group-by=none '~nexim4-daemon-light'
i 4.71-3 100
p 4.71-4 unstable 500
p 4.71-4 unstable 500
In addition to the above options, the information printed for each
version can be controlled by the command-line option -F. The order
in which versions are displayed can be controlled by the
command-line option --sort. To prevent aptitude from formatting
the output into columns, use --disable-columns.
add-user-tag, remove-user-tag
Adds a user tag to or removes a user tag from the selected group
of packages. If a package name contains a tilde ("~") or question
mark ("?"), it is treated as a search pattern and the tag is added
to or removed from all the packages that match the pattern (see
the section "Search Patterns" in the aptitude reference manual).
User tags are arbitrary strings associated with a package. They
can be used with the ?user-tag(tag) search term, which will select
all the packages that have a user tag matching tag.
why, why-not
Explains the reason that a particular package should or cannot be
installed on the system.
This command searches for packages that require or conflict with
the given package. It displays a sequence of dependencies leading
to the target package, along with a note indicating the installed
state of each package in the dependency chain:
$ aptitude why kdepim
i nautilus-data Recommends nautilus
i A nautilus Recommends desktop-base (>= 0.2)
i A desktop-base Suggests gnome | kde | xfce4 | wmaker
p kde Depends kdepim (>= 4:3.4.3)
The command why finds a dependency chain that installs the package
named on the command line, as above. Note that the dependency that
aptitude produced in this case is only a suggestion. This is
because no package currently installed on this computer depends on
or recommends the kdepim package; if a stronger dependency were
available, aptitude would have displayed it.
In contrast, why-not finds a dependency chain leading to a
conflict with the target package:
$ aptitude why-not textopo
i ocaml-core Depends ocamlweb
i A ocamlweb Depends tetex-extra | texlive-latex-extra
i A texlive-latex-extra Conflicts textopo
If one or more patterns are present, then aptitude will begin its
search at these patterns; that is, the first package in the chain
it prints will be a package matching the pattern in question. The
patterns are considered to be package names unless they contain a
tilde character ("~") or a question mark ("?"), in which case they
are treated as search patterns (see the section "Search Patterns"
in the aptitude reference manual).
If no patterns are present, then aptitude will search for
dependency chains beginning at manually installed packages. This
effectively shows the packages that have caused or would cause a
given package to be installed.
[Note] Note
aptitude why does not perform full dependency resolution;
it only displays direct relationships between packages. For
instance, if A requires B, C requires D, and B and C
conflict, "aptitude why-not D" will not produce the answer
"A depends on B, B conflicts with C, and D depends on C".
By default aptitude outputs only the "most installed, strongest,
tightest, shortest" dependency chain. That is, it looks for a
chain that only contains packages which are installed or will be
installed; it looks for the strongest possible dependencies under
that restriction; it looks for chains that avoid ORed dependencies
and Provides; and it looks for the shortest dependency chain
meeting those criteria. These rules are progressively weakened
until a match is found.
If the verbosity level is 1 or more, then all the explanations
aptitude can find will be displayed, in inverse order of
relevance. If the verbosity level is 2 or more, a truly excessive
amount of debugging information will be printed to standard
output.
This command returns 0 if successful, 1 if no explanation could be
constructed, and -1 if an error occurred.
clean
Removes all previously downloaded .deb files from the package
cache directory (usually /var/cache/apt/archives).
autoclean
Removes any cached packages which can no longer be downloaded.
This allows you to prevent a cache from growing out of control
over time without completely emptying it.
changelog
Downloads and displays the Debian changelog for each of the given
source or binary packages.
By default, the changelog for the version which would be installed
with "aptitude install" is downloaded. You can select a particular
version of a package by appending =version to the package name;
you can select the version from a particular archive or release by
appending /archive or /release to the package name (for instance,
/unstable or /sid).
download
Downloads the .deb file for the given package to the current
directory. If a package name contains a tilde character ("~") or a
question mark ("?"), it will be treated as a search pattern and
all the matching packages will be downloaded (see the section
"Search Patterns" in the aptitude reference manual).
By default, the version which would be installed with "aptitude
install" is downloaded. You can select a particular version of a
package by appending =version to the package name; you can select
the version from a particular archive or release by appending
/archive or /release to the package name (for instance: /unstable
or /sid).
extract-cache-subset
Copy the apt configuration directory (/etc/apt) and a subset of
the package database to the specified directory. If no packages
are listed, the entire package database is copied; otherwise only
the entries corresponding to the named packages are copied. Each
package name may be a search pattern, and all the packages
matching that pattern will be selected (see the section "Search
Patterns" in the aptitude reference manual). Any existing package
database files in the output directory will be overwritten.
Dependencies in binary package stanzas will be rewritten to remove
references to packages not in the selected set.
help
Displays a brief summary of the available commands and options.
Options
The following options may be used to modify the behavior of the actions
described above. Note that while all options will be accepted for all
commands, some options don't apply to particular commands and will be
ignored by those commands.
--add-user-tag tag
For full-upgrade, safe-upgrade, forbid-version, hold, install,
keep-all, markauto, unmarkauto, purge, reinstall, remove, unhold,
and unmarkauto: add the user tag tag to all packages that are
installed, removed, or upgraded by this command as if with the
add-user-tag command.
--add-user-tag-to tag,pattern
For full-upgrade, safe-upgrade forbid-version, hold, install,
keep-all, markauto, unmarkauto, purge, reinstall, remove, unhold,
and unmarkauto: add the user tag tag to all packages that match
pattern as if with the add-user-tag command. The pattern is a
search pattern as described in the section "Search Patterns" in
the aptitude reference manual.
For instance, aptitude safe-upgrade --add-user-tag-to
"new-installs,?action(install)" will add the tag new-installs to
all the packages installed by the safe-upgrade command.
--allow-new-upgrades
When the safe resolver is being used (i.e., --safe-resolver was
passed, the action is safe-upgrade, or
Aptitude::Always-Use-Safe-Resolver is set to true), allow the
dependency resolver to install upgrades for packages regardless of
the value of Aptitude::Safe-Resolver::No-New-Upgrades.
--allow-new-installs
Allow the safe-upgrade command to install new packages; when the
safe resolver is being used (i.e., --safe-resolver was passed, the
action is safe-upgrade, or Aptitude::Always-Use-Safe-Resolver is
set to true), allow the dependency resolver to install new
packages. This option takes effect regardless of the value of
Aptitude::Safe-Resolver::No-New-Installs.
--allow-untrusted
Install packages from untrusted sources without prompting. You
should only use this if you know what you are doing, as it could
easily compromise your system's security.
--disable-columns
This option causes aptitude search and aptitude versions to output
their results without any special formatting. In particular:
normally aptitude will add whitespace or truncate search results
in an attempt to fit its results into vertical "columns". With
this flag, each line will be formed by replacing any format
escapes in the format string with the corresponding text; column
widths will be ignored.
For instance, the first few lines of output from "aptitude search
-F '%p %V' --disable-columns libedataserver" might be:
disksearch 1.2.1-3
hp-search-mac 0.1.3
libbsearch-ruby 1.5-5
libbsearch-ruby1.8 1.5-5
libclass-dbi-abstractsearch-perl 0.07-2
libdbix-fulltextsearch-perl 0.73-10
As in the above example, --disable-columns is often useful in
combination with a custom display format set using the
command-line option -F.
This corresponds to the configuration option
Aptitude::CmdLine::Disable-Columns.
-D, --show-deps
For commands that will install or remove packages (install,
full-upgrade, etc), show brief explanations of automatic
installations and removals.
This corresponds to the configuration option
Aptitude::CmdLine::Show-Deps.
-d, --download-only
Download packages to the package cache as necessary, but do not
install or remove anything. By default, the package cache is
stored in /var/cache/apt/archives.
This corresponds to the configuration option
Aptitude::CmdLine::Download-Only.
-F format, --display-format format
Specify the format which should be used to display output from the
search and versions commands. For instance, passing "%p %V %v" for
format will display a package's name, followed by its currently
installed version and its available version (see the section
"Customizing how packages are displayed" in the aptitude reference
manual for more information).
The command-line option --disable-columns is often useful in
combination with -F.
For search, this corresponds to the configuration option
Aptitude::CmdLine::Package-Display-Format; for versions, this
corresponds to the configuration option
Aptitude::CmdLine::Version-Display-Format.
-f
Try hard to fix the dependencies of broken packages, even if it
means ignoring the actions requested on the command line.
This corresponds to the configuration item
Aptitude::CmdLine::Fix-Broken.
--full-resolver
When package dependency problems are encountered, use the default
"full" resolver to solve them. Unlike the "safe" resolver
activated by --safe-resolver, the full resolver will happily
remove packages to fulfill dependencies. It can resolve more
situations than the safe algorithm, but its solutions are more
likely to be undesirable.
This option can be used to force the use of the full resolver even
when Aptitude::Always-Use-Safe-Resolver is true. The safe-upgrade
command never uses the full resolver and does not accept the
--full-resolver option.
--group-by grouping-mode
Control how the versions command groups its output. The following
values are recognized:
* archive to group packages by the archive they occur in
("stable", "unstable", etc). If a package occurs in several
archives, it will be displayed in each of them.
* auto to group versions by their package unless there is
exactly one argument and it is not a search pattern.
* none to display all the versions in a single list without any
grouping.
* package to group versions by their package.
* source-package to group versions by their source package.
* source-version to group versions by their source package and
source version.
This corresponds to the configuration option
Aptitude::CmdLine::Versions-Group-By.
-h, --help
Display a brief help message. Identical to the help action.
--log-file=file
If file is a nonempty string, log messages will be written to it,
except that if file is "-", the messages will be written to
standard output instead. If this option appears multiple times,
the last occurrence is the one that will take effect.
This does not affect the log of installations that aptitude has
performed (/var/log/aptitude); the log messages written using this
configuration include internal program events, errors, and
debugging messages. See the command-line option --log-level to get
more control over what gets logged.
This corresponds to the configuration option
Aptitude::Logging::File.
--log-level=level, --log-level=category:level
--log-level=level causes aptitude to only log messages whose level
is level or higher. For instance, setting the log level to error
will cause only messages at the log levels error and fatal to be
displayed; all others will be hidden. Valid log levels (in
descending order) are off, fatal, error, warn, info, debug, and
trace. The default log level is warn.
--log-level=category:level causes messages in category to only be
logged if their level is level or higher.
--log-level may appear multiple times on the command line; the
most specific setting is the one that takes effect, so if you pass
--log-level=aptitude.resolver:fatal and
--log-level=aptitude.resolver.hints.match:trace, then messages in
aptitude.resolver.hints.parse will only be printed if their level
is fatal, but all messages in aptitude.resolver.hints.match will
be printed. If you set the level of the same category two or more
times, the last setting is the one that will take effect.
This does not affect the log of installations that aptitude has
performed (/var/log/aptitude); the log messages written using this
configuration include internal program events, errors, and
debugging messages. See the command-line option --log-file to
change where log messages go.
This corresponds to the configuration group
Aptitude::Logging::Levels.
--log-resolver
Set some standard log levels related to the resolver, to produce
logging output suitable for processing with automated tools. This
is equivalent to the command-line options
--log-level=aptitude.resolver.search:trace
--log-level=aptitude.resolver.search.tiers:info.
--no-new-installs
Prevent safe-upgrade from installing any new packages; when the
safe resolver is being used (i.e., --safe-resolver was passed or
Aptitude::Always-Use-Safe-Resolver is set to true), forbid the
dependency resolver from installing new packages. This option
takes effect regardless of the value of
Aptitude::Safe-Resolver::No-New-Installs.
This mimics the historical behavior of apt-get upgrade.
--no-new-upgrades
When the safe resolver is being used (i.e., --safe-resolver was
passed or Aptitude::Always-Use-Safe-Resolver is set to true),
forbid the dependency resolver from installing upgrades for
packages regardless of the value of
Aptitude::Safe-Resolver::No-New-Upgrades.
--no-show-resolver-actions
Do not display the actions performed by the "safe" resolver,
overriding any configuration option or earlier
--show-resolver-actions.
-O order, --sort order
Specify the order in which output from the search and versions
commands should be displayed. For instance, passing "installsize"
for order will list packages in order according to their size when
installed (see the section "Customizing how packages are sorted"
in the aptitude reference manual for more information).
The default sort order is name,version.
-o key=value
Set a configuration file option directly; for instance, use -o
Aptitude::Log=/tmp/my-log to log aptitude's actions to
/tmp/my-log. For more information on configuration file options,
see the section "Configuration file reference" in the aptitude
reference manual.
-P, --prompt
Always display a prompt before downloading, installing or removing
packages, even when no actions other than those explicitly
requested will be performed.
This corresponds to the configuration option
Aptitude::CmdLine::Always-Prompt.
--purge-unused
If Aptitude::Delete-Unused is set to "true" (its default), then in
addition to removing each package that is no longer required by
any installed package, aptitude will also purge them, removing
their configuration files and perhaps other important data. For
more information about which packages are considered to be
"unused", see the section "Managing Automatically Installed
Packages" in the aptitude reference manual. THIS OPTION CAN CAUSE
DATA LOSS! DO NOT USE IT UNLESS YOU KNOW WHAT YOU ARE DOING!
This corresponds to the configuration option
Aptitude::Purge-Unused.
-q[=n], --quiet[=n]
Suppress all incremental progress indicators, thus making the
output loggable. This may be supplied multiple times to make the
program quieter, but unlike apt-get, aptitude does not enable -y
when -q is supplied more than once.
The optional =n may be used to directly set the amount of
quietness (for instance, to override a setting in
/etc/apt/apt.conf); it causes the program to behave as if -q had
been passed exactly n times.
-R, --without-recommends
Do not treat recommendations as dependencies when installing new
packages (this overrides settings in /etc/apt/apt.conf and
~/.aptitude/config). Packages previously installed due to
recommendations will not be removed.
This corresponds to the pair of configuration options
Apt::Install-Recommends and Apt::AutoRemove::RecommendsImportant.
-r, --with-recommends
Treat recommendations as dependencies when installing new packages
(this overrides settings in /etc/apt/apt.conf and
~/.aptitude/config).
This corresponds to the configuration option
Apt::Install-Recommends
--remove-user-tag tag
For full-upgrade, safe-upgrade forbid-version, hold, install,
keep-all, markauto, unmarkauto, purge, reinstall, remove, unhold,
and unmarkauto: remove the user tag tag from all packages that are
installed, removed, or upgraded by this command as if with the
add-user-tag command.
--remove-user-tag-from tag,pattern
For full-upgrade, safe-upgrade forbid-version, hold, install,
keep-all, markauto, unmarkauto, purge, reinstall, remove, unhold,
and unmarkauto: remove the user tag tag from all packages that
match pattern as if with the remove-user-tag command. The pattern
is a search pattern as described in the section "Search Patterns"
in the aptitude reference manual.
For instance, aptitude safe-upgrade --remove-user-tag-from
"not-upgraded,?action(upgrade)" will remove the not-upgraded tag
from all packages that the safe-upgrade command is able to
upgrade.
-s, --simulate
In command-line mode, print the actions that would normally be
performed, but don't actually perform them. This does not require
root privileges. In the visual interface, always open the cache in
read-only mode regardless of whether you are root.
This corresponds to the configuration option Aptitude::Simulate.
--safe-resolver
When package dependency problems are encountered, use a "safe"
algorithm to solve them. This resolver attempts to preserve as
many of your choices as possible; it will never remove a package
or install a version of a package other than the package's default
candidate version. It is the same algorithm used in safe-upgrade;
indeed, aptitude --safe-resolver full-upgrade is equivalent to
aptitude safe-upgrade. Because safe-upgrade always uses the safe
resolver, it does not accept the --safe-resolver flag.
This option is equivalent to setting the configuration variable
Aptitude::Always-Use-Safe-Resolver to true.
--schedule-only
For commands that modify package states, schedule operations to be
performed in the future, but don't perform them. You can execute
scheduled actions by running aptitude install with no arguments.
This is equivalent to making the corresponding selections in
visual mode, then exiting the program normally.
For instance, aptitude --schedule-only install evolution will
schedule the evolution package for later installation.
--show-package-names when
Controls when the versions command shows package names. The
following settings are allowed:
* always: display package names every time that aptitude
versions runs.
* auto: display package names when aptitude versions runs if
the output is not grouped by package, and either there is a
pattern-matching argument or there is more than one argument.
* never: never display package names in the output of aptitude
versions.
This option corresponds to the configuration item
Aptitude::CmdLine::Versions-Show-Package-Names.
--show-resolver-actions
Display the actions performed by the "safe" resolver and by
safe-upgrade.
When executing the command safe-upgrade or when the option
--safe-resolver is present, aptitude will display a summary of the
actions performed by the resolver before printing the installation
preview. This is equivalent to the configuration option
Aptitude::Safe-Resolver::Show-Resolver-Actions.
--show-summary[=MODE]
Changes the behavior of "aptitude why" to summarize each
dependency chain that it outputs, rather than displaying it in
long form. If this option is present and MODE is not "no-summary",
chains that contain Suggests dependencies will not be displayed:
combine --show-summary with -v to see a summary of all the reasons
for the target package to be installed.
MODE can be any one of the following:
1. no-summary: don't show a summary (the default behavior if
--show-summary is not present).
2. first-package: display the first package in each chain. This
is the default value of MODE if it is not present.
3. first-package-and-type: display the first package in each
chain, along with the strength of the weakest dependency in
the chain.
4. all-packages: briefly display each chain of dependencies
leading to the target package.
5. all-packages-with-dep-versions: briefly display each chain of
dependencies leading to the target package, including the
target version of each dependency.
This option corresponds to the configuration item
Aptitude::CmdLine::Show-Summary; if --show-summary is present on
the command-line, it will override
Aptitude::CmdLine::Show-Summary.

-t release, --target-release release
Set the release from which packages should be installed. For
instance, "aptitude -t experimental ..." will install packages
from the experimental distribution unless you specify otherwise.
For the command-line actions "changelog", "download", and "show",
this is equivalent to appending /release to each package named on
the command-line; for other commands, this will affect the default
candidate version of packages according to the rules described in
apt_preferences(5).
This corresponds to the configuration item APT::Default-Release.
-V, --show-versions
Show which versions of packages will be installed.
This corresponds to the configuration option
Aptitude::CmdLine::Show-Versions.
-v, --verbose
Causes some commands (for instance, show) to display extra
information. This may be supplied multiple times to get more and
more information.
This corresponds to the configuration option
Aptitude::CmdLine::Verbose.
--version
Display the version of aptitude and some information about how it
was compiled.
--visual-preview
When installing or removing packages from the command line,
instead of displaying the usual prompt, start up the visual
interface and display its preview screen.
-W, --show-why
In the preview displayed before packages are installed or removed,
show which manually installed package requires each automatically
installed package. For instance:
$ aptitude --show-why install mediawiki
...
The following NEW packages will be installed:
libapache2-mod-php5{a} (for mediawiki) mediawiki php5{a} (for mediawiki)
php5-cli{a} (for mediawiki) php5-common{a} (for mediawiki)
php5-mysql{a} (for mediawiki)
When combined with -v or a non-zero value for
Aptitude::CmdLine::Verbose, this displays the entire chain of
dependencies that lead each package to be installed. For instance:
$ aptitude -v --show-why install libdb4.2-dev
The following NEW packages will be installed:
libdb4.2{a} (libdb4.2-dev D: libdb4.2) libdb4.2-dev
The following packages will be REMOVED:
libdb4.4-dev{a} (libdb4.2-dev C: libdb-dev P<- libdb-dev)
This option will also describe why packages are being removed, as
shown above. In this example, libdb4.2-dev conflicts with
libdb-dev, which is provided by libdb-dev.
This argument corresponds to the configuration option
Aptitude::CmdLine::Show-Why and displays the same information that
is computed by aptitude why and aptitude why-not.
-w width, --width width
Specify the display width which should be used for output from the
search command (by default, the terminal width is used).
This corresponds to the configuration option
Aptitude::CmdLine::Package-Display-Width
-y, --assume-yes
When a yes/no prompt would be presented, assume that the user
entered "yes". In particular, suppresses the prompt that appears
when installing, upgrading, or removing packages. Prompts for
"dangerous" actions, such as removing essential packages, will
still be displayed. This option overrides -P.
This corresponds to the configuration option
Aptitude::CmdLine::Assume-Yes.
-Z
Show how much disk space will be used or freed by the individual
packages being installed, upgraded, or removed.
This corresponds to the configuration option
Aptitude::CmdLine::Show-Size-Changes.
The following options apply to the visual mode of the program, but are
primarily for internal use; you generally won't need to use them yourself.
--autoclean-on-startup
Deletes old downloaded files when the program starts (equivalent
to starting the program and immediately selecting Actions -> Clean
obsolete files). You cannot use this option and
"--autoclean-on-startup", "-i", or "-u" at the same time.
--clean-on-startup
Cleans the package cache when the program starts (equivalent to
starting the program and immediately selecting Actions -> Clean
package cache). You cannot use this option and
"--autoclean-on-startup", "-i", or "-u" at the same time.
-i
Displays a download preview when the program starts (equivalent to
starting the program and immediately pressing "g"). You cannot use
this option and "--autoclean-on-startup", "--clean-on-startup", or
"-u" at the same time.
-S fname
Loads the extended state information from fname instead of the
standard state file.
-u
Begins updating the package lists as soon as the program starts.
You cannot use this option and "--autoclean-on-startup",
"--clean-on-startup", or "-i" at the same time.
Environment
HOME
If $HOME/.aptitude exists, aptitude will store its configuration
file in $HOME/.aptitude/config. Otherwise, it will look up the
current user's home directory using getpwuid(2) and place its
configuration file there.
PAGER
If this environment variable is set, aptitude will use it to
display changelogs when "aptitude changelog" is invoked. If not
set, it defaults to more.
TMP
If TMPDIR is unset, aptitude will store its temporary files in TMP
if that variable is set. Otherwise, it will store them in /tmp.
TMPDIR
aptitude will store its temporary files in the directory indicated
by this environment variable. If TMPDIR is not set, then TMP will
be used; if TMP is also unset, then aptitude will use /tmp.
Files
/var/lib/aptitude/pkgstates
The file in which stored package states and some package flags are
stored.
/etc/apt/apt.conf, /etc/apt/apt.conf.d/*, ~/.aptitude/config
The configuration files for aptitude. ~/.aptitude/config overrides
/etc/apt/apt.conf. See apt.conf(5) for documentation of the format
and contents of these files.

--------------------------------------------------------------------------
Name
aptitude-create-state-bundle -- bundle the current aptitude state
Synopsis
aptitude-create-state-bundle [options...] output-file
Description
aptitude-create-state-bundle produces a compressed archive storing the
files that are required to replicate the current package archive state.
The following files and directories are included in the bundle:
* $HOME/.aptitude
* /var/lib/aptitude
* /var/lib/apt
* /var/cache/apt/*.bin
* /etc/apt
* /var/lib/dpkg/status
The output of this program can be used as an argument to
aptitude-run-state-bundle(1).
Options
--force-bzip2
Override the autodetection of which compression algorithm to use.
By default, aptitude-create-state-bundle uses bzip2(1) if it is
available, and gzip(1) otherwise. Passing this option forces the
use of bzip2 even if it doesn't appear to be available.
--force-gzip
Override the autodetection of which compression algorithm to use.
By default, aptitude-create-state-bundle uses bzip2(1) if it is
available, and gzip(1) otherwise. Passing this option forces the
use of gzip even if bzip2 is available.
--help
Print a brief usage message, then exit.
--print-inputs
Instead of creating a bundle, display a list of the files and
directories that the program would include if it generated a
bundle.
File format
The bundle file is simply a tar(1) file compressed with bzip2(1) or
gzip(1), with each of the input directory trees rooted at ".".
See also
aptitude-run-state-bundle(1), aptitude(8), apt(8)
--------------------------------------------------------------------------
Name
aptitude-run-state-bundle -- unpack an aptitude state bundle and invoke
aptitude on it
Synopsis
aptitude-run-state-bundle [options...] input-file [ program
[arguments...]]
Description
aptitude-run-state-bundle unpacks the given aptitude state bundle created
by aptitude-create-state-bundle(1) to a temporary directory, invokes
program on it with the supplied arguments, and removes the temporary
directory afterwards. If program is not supplied, it defaults to
aptitude(8).
Options
The following options may occur on the command-line before the input file.
Options following the input file are presumed to be arguments to aptitude.
--append-args
Place the options that give the location of the state bundle at
the end of the command line when invoking program, rather than at
the beginning (the default is to place options at the beginning).
--help
Display a brief usage summary.
--prepend-args
Place the options that give the location of the state bundle at
the beginning of the command line when invoking program,
overriding any previous --append-args (the default is to place
options at the beginning).
--no-clean
Do not remove the unpacked state directory after running aptitude.
You might want to use this if, for instance, you are debugging a
problem that appears when aptitude's state file is modified. When
aptitude finishes running, the name of the state directory will be
printed so that you can access it in the future.
This option is enabled automatically by --statedir.
--really-clean
Delete the state directory after running aptitude, even if
--no-clean or --statedir was supplied.
--statedir
Instead of treating the input file as a state bundle, treat it as
an unpacked state bundle. For instance, you can use this to access
the state directory that was created by a prior run with
--no-clean.
--unpack
Unpack the input file to a temporary directory, but don't actually
run aptitude.
