Cannot connect to mySQL server

Hello.

Is MySQL also managed by Docker containers?
In that case, you need to check whether the MySQL container is started properly.
Can you confirm that the MySQL container is starting normally using the "docker ps" command?

mysql is not managed by Docker.

Here where mysql is installed: $ which mysql /usr/bin/mysql $ mysql --version mysql Ver 15.1 Distrib 10.5.25-MariaDB, for Linux (x86_64) using EditLine wrapper

When trying to restart it I a getting this error: $ service mysql start Redirecting to /bin/systemctl start mysql.service Failed to start mysql.service: The name org.freedesktop.PolicyKit1 was not provided by any .service files See system logs and 'systemctl status mysql.service' for details.
