ubuntu not shutting down 18.10 or Shutdown Hangs on “A stop job is running to for Mysql Community Server” on Ubuntu

Got the same issue, found a possible explanation: my cloud provider store time in local timezone (earlier than UTC); at startup MySQL boot first, then NTP, which updates the time to UTC; therefore, MySQL literally “started in the future” (sounds interesting).

Running sudo dpkg-reconfigure tzdata should do the trick
