=== What files did this package install? ===

The synaptic gui will have a 'properties' tab that lists all the files installed. On the console, you can use <code>dpkg-query --listfiles package_name</code>. I don't use <code>apt-file</code> since dpkg is already installed on a base system.

I don't use <code>apt-file</code> since '''[https://man7.org/linux/man-pages/man1/dpkg.1.html dpkg]''' is already installed on a base system.

=== What package provides file Y? ===

You can also use the web interface at http://packages.ubuntu.com/

=== What PPA and sources am I installing from? ===

It is surprising that I haven't found a simple command to list apt sources.

<code>grep -r --include '*.list' '^deb ' /etc/apt/sources.list*</code>

or even pretty up the output a bit [https://askubuntu.com/a/741948/146518 from here]

=== Remove old kernels ===

Line 48:

dpkg -l linux-image* | awk '/^ii/ { print $2 }' | grep -P '[0-9]+\.[0-9]+\.[0-9\-]+[0-9]+'

</syntaxhighlight>

Manually compose an <code>apt-get purge</code> invocation of the kernels you don't want (keep the running kernel and the prior as a fallback).

You might also have several '''removed''' kernels with the configuration files still hanging around. These will be marked with status '''rc''' (remove configured) instead of 'ii' like in the awk command above. So, use something like <syntaxhighlight lang="bash">

echo "apt purge $(dpkg -l | egrep '^rc' | awk 'ORS=" " {print $2}')"
