Just chiming in until someone can respond with recent firsthand
experience. If you go to e.g. "man apt" or "man apt-get", you'll see
flag options that are about cleaning up downloaded files. I did this
once a couple years ago and so can't remember which one worked for
what you're asking, but it does work. Whichever option it is, it
leaves the currently installed deb in place and cleanses out anything
that's no longer in use.
Thank you to the Developers who have left this as a User CHOICE that
must be manually addressed if a different option is desired. Users
have their various reasons for maintaining older install debs. It's
nice to know they're always safe from sudden, silent deletion.
Afterthought as I write that because of an experience that I
encountered. There's additionally a value you can define that
automatically performs the above function every time you update and
then upgrade your system's packages.
Remembering that detail led to a search that didn't find a tip on
which file contains that changeable value, but I did find the
following (might need fixed to be one usable line):
https://www.debian.org/doc/manuals/debian-reference/ch02.en.html#_basic_package_management_operations_with_the_commandline
If that link doesn't bounce partway down the page to the appropriate
section, CTRL+F (or similar browser find feature) on that "operations
with the commandline" part of the link should help. It's Section 2.2.2
that contains those various interesting values.
If anyone test drives those for the first time, especially without
fully understanding what the notes are saying the options do, PLEASE
make sure to back up your system first. Been there, done that without
backing up in the past. It's not pretty..
