Thanks for reporting this bug and trying to make Ubuntu better. Looking at the logs, I noticed you tried to install mariadb on top of mysql, that's not a supported use case and you should try to pick one of them. Once you tried to install mariadb, mysql was supposed to be removed and for some reason the pre-removal script failed when trying to stop the service. It seems that the systemd unit file was not present:
Failed to stop mysql.service: Unit mysql.service not loaded. invoke-rc.d: initscript mysql, action "stop" failed. Failed to preset unit: File mysql.service: Link has been severed /usr/bin/deb-systemd-helper: error: systemctl preset failed on mysql.service: No such file or directory Failed to start mysql.service: Unit mysql.service not found. invoke-rc.d: initscript mysql, action "start" failed. Unit mysql.service could not be found. Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I am marking this bug as 'Incomplete'. However, if you believe that this is really a bug in Ubuntu, then we would be grateful if you would provide a more complete description of the problem with steps to reproduce, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to "New".
