Thousands of programs are freely available to install in <span>Kubuntu</span>. These
programs are stored in software archives (<span class="emphasis"><em>repositories</em></span>) and
are made available for installation over the Internet. This makes it easy
to install new programs in <span>Kubuntu</span>. It is also secure, because each program
is built specifically for <span>Kubuntu</span> and is checked thoroughly before it is
installed. <span>Kubuntu</span> repositories are categorized into four groups:
</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>Main</p></li><li class="listitem"><p>Restricted</p></li><li class="listitem"><p>Universe</p></li><li class="listitem"><p>Multiverse</p></li></ul></div><p>
Two factors are used to determine categories:
</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>
The level of support that software development teams provide for a program.
</p></li><li class="listitem"><p>
The level of compliance the program has to the <a class="ulink" href="http://www.ubuntu.com/ubuntu/philosophy" target="_top">Free Software Philosophy</a>.
</p></li></ul></div><p>
More information about the Repositories is available on the <a class="ulink" href="http://www.ubuntu.com/ubuntu/components" target="_top">Ubuntu website</a>.
</p><p>
The standard <span>Kubuntu</span> LiveCD contains some software from the
<span class="emphasis"><em>Main</em></span> and <span class="emphasis"><em>Restricted</em></span> categories. Once
a system has information about the Internet-based locations for these
repositories, more programs are available for installation. Using the
software package management tools installed by default, it is possible to
discover, install, and update any piece of software directly over the Internet
without the need for the LiveCD.

Select
<span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guimenu">Settings</span></span> → <span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guimenuitem">Configure Software Sources</span></span>
in the <span class="application">Muon</span> package manager window.
</p></li><li class="step"><p>
An administrative password is required in order to proceed.
</p></li><li class="step"><p>
Next, click on the <span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Other Software</span></span> tab. Existing
repositories can be enabled or disabled by checking the appropriate boxes
in the upper section. To add a new repository, click the
<span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Add...</span></span> button.
</p></li><li class="step"><p>
Enter the repository address. The proper format is required, and looks similar
to this:
</p><pre class="screen">deb http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu oneiric
main</pre><p>
</p></li><li class="step"><p>
Click the <span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">OK</span></span> button to add the repository.
</p></li><li class="step"><p>
Click the <span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Close</span></span> button.
</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
A prompt will appear to update the package list. Doing so will allow
<span class="application">Muon</span> to find the newly available software.
</p></div></li><li class="step"><p>
To remove a repository, select it in <span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Software Sources</span></span>, and
press the <span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guibutton">Remove</span></span> button. When the process is complete,
press the <span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guibutton">Close</span></span> button.
</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
A prompt will appear to update the package list. Doing so will make
<span class="application">Muon</span> forget the no longer available software.
