[Bug 1988690] Re: could not collect all packages for upgrade

Reviewing the files from your upgrade attempt, you have installed
pipewire packages from the pipewire-debian/pipewire-upstream PPA. Some
of the packages installed are newer than those in the official archive,
which is keeping some pipewire-related packages installed which then
prevents the upgrade from being calculated. Please try using the ppa-
purge tool to remove packages installed from ppa:pipewire-
debian/pipewire-upstream. After that you can try upgrading again and if
it still fails open a new bug report. Thanks and good luck!
