<h1>11. Backporting software updates<a class="headerlink" href="#backporting-software-updates" title="Permalink to this headline"></a></h1>
<p>Sometimes you might want to make new functionality available in a stable
release which is not connected to a critical bug fix. For these scenarios
you have two options: either you <a class="reference external" href="https://help.launchpad.net/Packaging/PPA">upload to a PPA</a>
or prepare a backport.</p>
<div class="section" id="personal-package-archive-ppa">
<h2>11.1. Personal Package Archive (PPA)<a class="headerlink" href="#personal-package-archive-ppa" title="Permalink to this headline"></a></h2>
<p>Using a PPA has a number of benefits. It is fairly straight-forward, you
don&#8217;t need approval of anyone, but the downside of it is that your users will
have to manually enable it. It is a non-standard software source.</p>
<p>The <a class="reference external" href="https://help.launchpad.net/Packaging/PPA">PPA documentation on Launchpad</a> is fairly comprehensive and should get
you up and running in no time.</p>
</div>
<div class="section" id="official-ubuntu-backports">
<h2>11.2. Official Ubuntu Backports<a class="headerlink" href="#official-ubuntu-backports" title="Permalink to this headline"></a></h2>
<p>The Backports Project is a means to provide new features to users. Because of
the inherent stability risks in backporting packages, users do not get
backported packages without some explicit action on their part. This
generally makes backports an inappropriate avenue for fixing bugs. If a
package in an Ubuntu release has a bug, it should be fixed either through the
<a class="reference internal" href="security-and-stable-release-updates.html"><span class="doc">Security Update or the Stable Release Update
process</span></a>, as appropriate.</p>
<p>Once you determined you want a package to be backported to a stable release,
you will need to test-build and test it on the given stable release.
<code class="docutils literal"><span class="pre">pbuilder-dist</span></code> (in the <code class="docutils literal"><span class="pre">ubuntu-dev-tools</span></code> package) is a very handy tool
to do this easily.</p>
<p>To report the backport request and get it processed by the Backporters team,
you can use the <code class="docutils literal"><span class="pre">requestbackport</span></code> tool (also in the <code class="docutils literal"><span class="pre">ubuntu-dev-tools</span></code>
package). It will determine the intermediate releases that package needs to
be backported to, list all reverse-dependencies, and file the backporting
request.  Also will it include a testing checklist in the bug.</p>
