[NTLUG:Discuss] Command line

[David Stanaway]

apt-get remove will ininstall the package

Your example though is a psuedo package that depends on a bunch of other 
packages which don't have a dependency on

kubuntu-desktop

So, you will probably still have all your KDE packages etc still installed.

In that situation, I try and pick a few core dependencies of the system I want to remove then apt-get remove them, eg. KDE libraries and Qt libraries. That should via dependencies cascade to most of the KDE suit. Be careful though that you don't have any unintended consequences.

dpkg --get-selections 


is a handy tool for snapshotting the installed state of packages. 


There is a util you can install which looks for orphaned packages which 
can be left behind by installing something, then uninstalling (But 
leaving dependencies).

I think it was called deborphan. You could use deborphan in combination 
with apt-get-remove for several passes until all your orphaned libraries 
etc are gone.
