In reply to Jorg. If you are moving to a folder under the home partition and you are using systemd to start the database service, then this error can occur. You need to create a folder with:

mkdir /etc/systemd/system/mariadb.service.d/

Then create a file there with:

sudo echo -e "[Service]\nProtectHome=false\nProtectSystem=full\n" > /etc/systemd/system/mariadb.service.d/override.conf

Run:

sudo systemctl daemon-reload 
sudo systemctl start mysql

and you should be all set if the home folder restriction was your problem.

Hi, the part after copying the database files, restart MySQL – commands need revision.

Error in part 3 you say my.cnf but in the commands, you use my.conf this may be confusing...
