Hello,

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

While the symptom is similar to the one observed in https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1899248, I see an additional error in your logs:

 MySQLConf.etc.mysql.my.cnf: Error: [Errno 40] Too many levels of symbolic links: '/etc/mysql/my.cnf'

It seems the service needs a restart, but it cannot perform one due to a circular symlink for your configuration file at /etc/mysql/my.cnf.

Could you confirm that this configuration file is an actual circular symbolic link?

Would you mind providing more information on your configuration setup? Namely, it would be interesting to understand how that file turned out to become a circular symlink.

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.
