What does
apt remove --purge <unwanted package> ; apt autoremove
not do that you want done?
Unfortunately it does not know what packages are unwanted, nor
do I (the user) to tell it.
We are all familiar with the situation when after a long period of
usage, a system becomes full of software which we once installed for
some purpose and then abandoned or disused. A gentle hint on what is an
<unwanted package> would be very much appreciated at such moments.
Maybe the high-level package management software (aptitude?) is better
at that?
Of course, in any serious server environment, one is likely to have lots
of software that was NOT installed through dpkg or apt - ranging from
stuff installed directly from tarballs, to local configurations & scripts.
As far as I can tell, the only way to get to a "pristine" system, is to
rebuild from scratch.
