What I did was to run:
$ dpkg-query -W -f '${Package}\n' | LC_ALL=C sort
to get a list of current packages. Then I downloaded:
https://packages.debian.org/stable/allpackages?format=txt.gz
and ran it through:
$ zcat allpackages\?format\=txt.gz | tail -n +7 | cut -d\ -f 1
for a list of bookworm packages. (Sort it as well if you're a worrier.)
Then I compared the new and old files with diff -U9999 piped
into less, and searched with /^\+ Most of the 107 "missing" packages
were libs, which don't really interest me, then versioned kernels, gcc
and python.
Cheers,
David.
