<p>Even though old kernels have been removed (as described in this preview <a href="http://goo.gl/fU69Am">post</a>), <code>linux-headers</code> packages may still be left behind using precious disk space. Here's how to remove them.</p>
</section>
<section id="section-install">
<h4>Recovering disk space</h4>
<p>Open a terminal window and run:</p>
<!--INFOLINKS_OFF-->
<pre><code>current_kernel=$(uname -r) && dpkg-query -W -f='${Package}\n' 'linux-headers-[0-9].[0-9][0-9]*' | egrep -v ${current_kernel%-generic} | xargs sudo apt-get remove -y
</code></pre>
<!--INFOLINKS_ON-->
<p>Running this command I was able to recover a little bit more than 1GB of disk space:</p>
<!--INFOLINKS_OFF-->
<pre><code>After this operation, <strong>1075 MB disk space will be freed.</strong>
</code></pre>
<!--INFOLINKS_ON-->
</section>
<section id="section-usage">
<h4>Disclaimer</h4>
<p>Use this command at your own risk. To see what the command will remove just run the first part, without <code>apt-get remove</code>:</p>
<!--INFOLINKS_OFF-->
<pre><code>current_kernel=$(uname -r) && dpkg-query -W -f='${Package}\n' 'linux-headers-[0-9].[0-9][0-9]*' | egrep -v ${current_kernel%-generic}

<p><strong>Problem</strong></p>
<p>When trying to open an URL with Firefox (eg. via File Manager of Mail Reader), Firefox opens a blank page or your homepage (if it's set to something other than blank) instead of the URL.</p>
<p>This situation has been reported and confirmed as a bug (bug #1427144 on launchpad).</p>
<p><strong>Solution</strong></p>
<p>It seems that the problem is in the file <code>/usr/share/xfce4/helpers/firefox.desktop</code>, and replacing the last line fixes it.</p>
</section>
<section id="section-install">
<h4>Fix</h4>
<p>You can fix it manually (1) or just run the command (2) that creates a backup and automatically replaces the broken line.</p>
<ol>
<li>
<p><strong>Manual</strong>: Open <code>/usr/share/xfce4/helpers/firefox.desktop</code> with your favorite text editor and root permissions (eg. <code>sudo mousepad /usr/share/xfce4/helpers/firefox.desktop</code>). Then replace the following line:</p>
<!--INFOLINKS_OFF-->
<pre><code>X-XFCE-CommandsWithParameter=%B -remote "openURL(%s)";%B %s;</code></pre>
<!--INFOLINKS_ON-->
<p>With this one:</p>
<!--INFOLINKS_OFF-->
<pre><code>X-XFCE-CommandsWithParameter=%B %s;%B %s;</code></pre>
<!--INFOLINKS_ON-->
</li>
<li>
<p><strong>Automatic</strong>: Open a terminal window and run:</p>
<!--INFOLINKS_OFF-->
<pre><code>cd /usr/share/xfce4/helpers/ && sudo cp firefox.desktop firefox.desktop.bak && sudo sed -i 's/-remote "openURL(%s)"/%s/' firefox.desktop
</code></pre>

</section>
<section id="section-install">
<h4>Solution</h4>
<p>This can be easily fixed by adding <code>uid=1000</code> to your mounting options in <code>/etc/fstab</code>.</p>
<ol>
<li>Open <code>fstab</code> with root permissions: <code>sudo mousepad /etc/fstab</code> (replace <code>mousepad</code> with the command for your favorite text editor).</li>
<li>Find the line corresponding to your NTFS partition (see example bellow for help).</li>
<li>Add <code>uid=1000</code> after <code>umask=007</code>, use commas (again see example).</li>
</ol>
<h5>Example</h5>
<p>How it looks by default:</p>
<!--INFOLINKS_OFF-->
<pre><code># /media/Data was on /dev/sdb6 during installation
UUID=702907667255DAFB /media/Data ntfs defaults,umask=007,gid=46 0 0

<!--INFOLINKS_ON-->
<p>After adding <code>uid=1000</code>:</p>
<!--INFOLINKS_OFF-->
<pre><code># /media/Data was on /dev/sdb6 during installation

<p><strong>Problem</strong></p>
<p>The message <i>"The following packages have been kept back"</i> appears when upgrading (<code>apt-get upgrade</code>), and the packages identified are not upgraded.</p>
</section>
<section id="section-install">
<h4>Solution</h4>
<p>This happens when the dependencies of the identified packages changed and new packages need to be installed. We need to use <code>dist-upgrade</code> in order to install the new dependencies and upgrade the packages:</p>
<!--INFOLINKS_OFF-->
<pre><code>sudo apt-get dist-upgrade
</code></pre>
