Install MySQL Server after an upgrade from Ubuntu 14.04 to 16.04
What a terrible experience on an upgrade. Problem after problem. I finally got the network up, got PHP and Apache installed, but now after more hours of failed attempts, the closest I've got to mysql server install is this:

I ran into a similar situation recently with an upgrade from Ubuntu 16.04 to 18.04. I never did figure out how to get things working without starting over from scratch. Hopefully, you backed up your database(s) before starting your upgrade. Assuming you did that, I got things working by completely removing and purging mysql-client and mysql-server. I then flushed the apt cache completely and made sure that dpkg wasn't showing any remnants (dpkg -l didn't show anything with 'rc' status). Then I checked my repositories to make sure I was using the appropriate sources (should be xenial for 16.04). I did a "sudo apt-get update" to retrieve current package information. Then I re-installed mysql-client and mysql-server. After recovering my databases I was good to go.
