I upgraded my Fedora distro from v.40-41. I did

pip install wheel mailman psycopg2-binary

When running the mailman command, I get

alembic.util.exc.CommandError: Can't locate revision identified by '8cc1f79f4459'

How do I solve this?

mailman --version gives:

GNU Mailman 3.3.9 (Tom Sawyer)

But in my old venv installation folder, I have files like venv.old/lib/python3.12/site-packages/mailman-3.3.10.dist-info/RECORD:mailman-3.3.10.dist-info/entry_points.txt, e.g. 3.3.10. How could that happen? And how do I go on further to get mailman3 up and running?

Thanks, Lars
