There are tools like > `deborphan` and `aptitude search ~o` that may tell you about them. In aptitude's interactive mode there is a special section for them, that only shows up if there are any. Does this count as "automatism"? :) For completeness, obsolete packages can also happen within the same release, e.g. old linux-image packages. APT is configured to keep one older version by default, the others are fair game for 'autoremove'. > The release notes recommend proactively removing obsolete packages: > > https://www.debian.org/releases/bullseye/amd64/release-notes/ch-upgrading.en.html#for-next Yes, though some care might be needed, depending on the situation[1]. E.g. leafpad was replaced by mousepad in buster. If you just execute the 'aptitude purge ~o' aptitude might want to remove the entire LXDE environment, because the lxde metapackage in buster has 'Depends: leafpad | mousepad'. The solution in this particular case is to tell aptitude to install (and set as 'automatic') mousepad in the same run[2]. [1] Always inspect the list of proposed removals by apt/itude carefully before confirming. In case it looks wrong just ask on the list with the copy-paste of the full output. [2] There are several methods to do that, depending on your familiarity with aptitude. Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser
