    Hello, there is MariaDB installed using the apt command on your server. It is recommended that you deal with it.
    Make a snapshot backup of the server before operation.

    apt remove mariadb*
    cd /etc/systemd/system/
    rm mysqld.service mysql.service
    systemctl daemon-reload
    /etc/init.d/mysqld start
