What to do?

Follow the instruction [here](https://askubuntu.com/questions/760724/16-04-upgrade-broke-mysql-server) seemed to get it going for me. — Alex Haynes, Apr 14 '20 at 09:28

If nothing else helps, try to

Copy your MySQL data files to some safe place (external HDD, whatever)
Install Ubuntu 14.04 to a temporary virtual machine
Copy your MySQL data files to this new virtual machine
Use mysqldump or similar tool to perform a dump of your databases
Copy the dumps to your upgraded Ubuntu machine
Import the dumps
