This seems to be a bug in command-not-found, Python, or any of the libraries it used. For further investigation, we need a core dump from that process, did apport not prompt you for that?

I never used apport. I used `ubuntu-bug apt` to generate the bug report. I don't see a core dump anywhere.

This appears to be a duplicate of https://bugs.launchpad.net/ubuntu/+source/command-not-found/+bug/1876034. It may be worth holding off using the "Mark as duplicate" function as it hides the duplicate from the search results. Since 1876034 doesn't contain the error the end-user sees (this bug report does), it would be easy to miss there's an existing issue raised (and already one other bug report marked as duplicate).
