Hello Michael and thanks for this bug report.

I expected to see the /var/log/mysql/error.log file attached to this Apport generated bug report, but it's not there. Could you please check if the file exists and if it does attach it manually to this bug report?

I can't reproduce the problem on a fresh Focal system. Are you able to provide a minimal set of steps to reproduce the issue from scratch? Without steps to reproduce it's difficult for a developer to confirm this issue is a bug rather than a local configuration problem, and in general to begin working on it.

I'm setting the status of this report to Incomplete for the moment. Please change it back to New after commenting back and we'll look at it again. Thanks!

Please look at bug #1899075 if it look similar to your use case.

Thanks for filing this bug to help make Ubuntu better. Unfortunately there's not enough information to see what went wrong. The error log might have held some info but presumably by now that's no longer available. Please file a new bug if the issue occurs again.
