Then why not just to remove
$ apt remove --purge mysql-common

Your report was an upgrade, is this blocking the removal of the package as well?

This seems more like a config issue to me actually.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. 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.

That looks good for your case I'd think https://askubuntu.com/questions/643251/having-trouble-installing-and-removing-mysql-in-ubuntu

Try following the reinstall and fixup actions discussed there.
