Sorry, I was not very clear, and thank you for the prompt reply. I have tried the workaround before I posted my comment here. It does not work. Note I cannot uninstall MySQL. I need it. And yes, I don't want the service to run on boot, preferring to start it manually (Although I can change this of course, probably pads a couple milliseconds @ boot time but SSD speed is almost negligible). :)
From what I read above and in other reports, this is what I have done so far:
1) enable the service - systemctl enable mysql.service
2) start if not yet started - systemctl start mysql.service
3) apt upgrade
But it seems the `enable` command has some errors - sudo systemctl enable mysql.service
Result:
Synchronizing state of mysql.service with SysV init with /lib/systemd/systemd-sysv-install...
Executing /lib/systemd/systemd-sysv-install enable mysql
insserv: warning: current start runlevel(s) (empty) of script `mysql' overrides LSB defaults (2 3 4 5).
update-rc.d: error: no runlevel symlinks to modify, aborting!
