Hello Kaylee and thanks for filing this bug report. From the attached logs I see that updating mailman failed because:

OSError: [Errno 2] No such file or directory: '/var/lib/mailman/qfiles/out/1645451769.107923+c16c9118034896266b63a04bfa1653d5c627b208.bak'

Perhaps that backup file has been manually removed at some point?

Since it seems likely to me that this is a local problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete. If you believe that this is really a bug, we'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.

(Side note: keep in mind that Focal is the latest Ubuntu release shipping mailman2.)

It's probably an issue on my side. I'm fairly new at system administration and am setting up a VPS for the first time. Thanks for your time!
