I am trying to set up MariaDB server under xubuntu 20.04 and import all the db's I had previously on another machine under xubuntu 18 (following the notes I took when doing it there coming from opensuse).
The installed mariadb has datadir in /var/lib/mysql, and contains only a "null" msyql db with a root user with no password (as tested entering as sudo mysql -u root mysql which requires my personal passwd password).
I stopped the MariaDB server from the system installation, edited the mariadb.conf.d/50-server.cnf with my few changes (chief of them is that the datadir is /elsewhere/Mysql), then
I rsynced all my databases from the previous machine (I had prepared also mysql dumps,but since the MariaDB version is the same, I thought this was easier).
Then a systemctl start mariadb returns with no error but a systemctl status mariadb shows that the post-processing debian-start has given the error reported in the subject.
MariaDB looks running OK. I can enter with the mysql client in all my personal databases using my old mysql password, and I can also enter as mysql root using my old mysql root password. Those passwords are of course not the same as the passwd ones.
So I can work normally, only there is this slightly disturbing message from debian-start as if it was trying to login using no root password (which succeeds using the original mariadb.conf.d/50-server.cnf).
This did not occur on Ubuntu 18 (there I had to set ProtectHome=false, but apparently this is not required on 20)
Any way to get rid of the annoying message, or should I just live with it since all the rest works ?
