[Andreas Hasenack]

Thanks for filing this bug in Ubuntu.

I'm seeing this in the mysql error log:
2018-09-01T07:31:57.179473Z 0 [Note] Server hostname (bind-address): '127.0.0.1'; port: 3306
2018-09-01T07:31:57.179486Z 0 [Note]   - '127.0.0.1' resolves to '127.0.0.1';

2018-09-01T07:31:57.179547Z 0 [ERROR] Aborting

Looks like something else is listening on mysql's port (3306).

After reboot, is mysql running? Could you show the output of these commands please:
sudo netstat -anp
sudo systemctl status mysql
tail /var/log/mysql/error.log
sudo apt update
sudo apt -f install
tail /var/log/mysql/error.log # again

Thanks
