I think there was an issue on my end. Most likely I think it was the fact that the upgrade process from 15.10 to 16.04LTS was interrupted by my 5 year old daughter who snuck in to the room and pressed some keys on the keyboard. The last error I saw on the upgrade was something like "Adding system-journal group...group already exists....exiting."
I waited a while before touching the system, as I wasn't sure if the install was still trying to do something in the background and I didn't want to make things worse. A few reboots, and some "sudo apt-get -f install" and "sudo apt-get dist-upgrade", and I was able to get through the upgrade process, aside from the mySQL issue. I was able to resolve that by killing the mysqld process and then running system updates, which then completed the mySQL install with no errors.
