Hi, I am running into this same issue after dist upgrading from buster to bullseye then bookworm today. The trac package of bookworm-backports is broken. Building the trac package from buster on bookworm is not an option, because bookworm no longer provides the old python packages from buster. I do need to get trac up and running after the upgrade. What packages do I need to backport manually from testing to make the bookworm-backports trac package work on bookworm or will the backport get fixed. Thank you.
Regards, -- Christian
