====== apt hold ======

Prevent packages from auto-updated via apt:

<code>
sudo apt-mark hold packagename
</code>

Show all holds:
<code>
apt-mark showhold
</code>

Remove mark:
<code>
sudo apt-mark unhold packagename
</code>

Same for dpkg:
<code>
echo "packagename hold" | sudo dpkg --set-selections
</code>
<code>
dpkg --get-selections | grep hold
</code>
<code>
echo "packagename install" | sudo dpkg --set-selections
</code>
