Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

You have removed mysql at
 2019-05-08 22:38:38
And then (re)installed it at
  2019-05-08 22:55:45

But the log shows:
  invoke-rc.d returned 5
  There is a MySQL server running, but we failed in our attempts to stop it.
  Stop it yourself and try again!

So clearly there is something else running it can't get rid of.
That is custom to your system config and not reproducible in a simple test that I've done.

You'd need to check what is still running that it fails on and resolve that situation.

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.
