There is a way to find the obsolete packages installed on _your_ system, which is probably what you really care about. After preparing your sources.list to add the bookworm repositories and remove the bullseye ones[1], run "apt update". Then "apt list '~o'" lists all the packages which are no longer available. See apt-patterns(7). Good luck, Sven 1. https://www.debian.org/releases/bookworm/amd64/release-notes/ch-upgrading.en.html
