Then I get:

[ERROR] Fatal error: Can't change to run as user 'mysql' ;  Please check that the user exists!

Workaround:

cd /var/lib/mysql
sudo adduser mysql
sudo chown mysql:mysql -R /var/lib/mysql

Then I get:

[Warning] Using unique option prefix myisam-recover instead of myisam-recover-options is deprecated and will be removed in a future release. Please use the full name instead.

After that I give up with next error:

Because this didn't work:

sudo mysql_install_db --user=mysql --basedir=/usr/ --ldata=/var/lib/mysql/
FATAL ERROR: Could not find my-default.cnf

If you compiled from source, you need to run 'make install' to
copy the software into the correct location ready for operation.

If you are using a binary release, you must either be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.
