And the bug report shows this crash happened with python3-apt 1.9.10, which was a prerelease version of python3-apt before Ubuntu 20.04 LTS came out. So I'm surprised another user has just marked this bug as affecting them, causing the report to bubble up to the top. We would need some concrete evidence that this failure happens with released versions of the software to take further action here.
