Re: After upgrade, what do you do about "removed" and "obsolete" packages ?

Hi,

i wonder why none of the electricians on this list has an anecdote to
share about dealing with "obsolete" packages after upgrade.
No triumphs, defeats, or global catastrophes ?

So the smaller list of packages can be dealt with what the upgrade
instructions propose:
  apt purge '~c'


There remains the list of 220 "obsolete" packages.

But several of those packages were surely installed manually by me via
dpkg -i after being made made as descibed in
  https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#s-common-building
The predicate "obsolete" is not the same as "automatically installed".
I understand that obsolete means having no successor package in the
upgraded Debian release.

How could i get a list of only the automatically installed obsolete
packages ?
(I still did not find any documentation about the '~c' or '~o' with
"apt list".)

Google leads me to apt-mark for that purpose.
But i am not sure whether the commercial package which i have to keep
will be preserved with "apt autoremove".
Is there a way to do a dry run which only tells what would happen if i
were more courageous ?


Have a nice day :)
