Package: dpkg Version: 1.22.22 Severity: normal When doing `apt purge', apt runs `dpkg --set-selections' as one of the steps. And during this step, dpkg updates some fields of installed packages from its `available' database.
On one of my machines where this issue has been found, the file /var/lib/dpkg/available seems to has been created during initial install, and never updated. It contains information about packages which were available back in 2015. And `dpkg --set-selections' updates some info about installed packages from this file. For example, it "fixed" Priority for e2fsprogs from optional to required, changed libcap2 priority from optional to standard, changed tzdata section from localization to libs and so on - more than 50 changes in total. Obviously this is all wrong now for current packages, but it was correct back 11 years ago. Apparently we shoud decide whenever we should keep this file up to date, or drop it. But doing it this way is wrong. Thanks, /mjt
