Description
When switching from upstream 8.0, once the packages are removed mysql.service gets masked. After PS packages are installed server won't start because of this:
root@xenial:~# service mysql start
Failed to start mysql.service: Unit mysql.service is masked.
Unmasking the service resolves the issue:
root@xenial:~# systemctl unmask mysql.service
Removed symlink /etc/systemd/system/mysql.service.
root@xenial:~# service mysql start
root@xenial:~# mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 8.0.13-3 Percona Server (GPL), Release '3', Revision 'a920dd6'
We should either document this or unmask the service automatically once we install our packages.
@Evgeniy Patlan thank you very much. I wonder what @Hrvoje Matijakovic ran into then.
Does this need further review/input from @Hrvoje Matijakovic then?

@Evgeniy Patlan Hrvoje is out, and apparently this happens on 8.0 only. Can you have a look please after your Christmas break? Thank you

8.0 triage - Hrvoje reports this probably happens on 5.7 as well, but hasn't been able to verify. This should be filed as an upstream bug (this is incorrect behavior). Fix if Time.
