I've just upgraded my list server from 18.04 to 20.04 and this bug is a show-stopper for 20.04. Without the hand-patching mentioned before, mailman will fail to do things like hold mail for moderation, which makes it close to unusable.
I would very much like to see a fix backported. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877701 Title: Mailman3 3.2.2-1 is incompatible with Python3 3.8.2-0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mailman3/+bug/1877701/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
