    To ensure that everything is clean, you not only need to purge MySQL (and MariaDB) with:

    sudo apt-get purge mysql* mariadb*

    But you also need to remove old MySQL config folders, with:

    sudo rm -rf /etc/mysql
sudo rm -rf /var/log/mysql
sudo rm -rf /var/lib/mysql
sudo rm -rf /var/lib/mysql-files
sudo rm -rf /var/lib/mysql-keyring

    After these steps and correctly adding the MariaDB repositories, you can finally:

    sudo apt update
sudo apt install mariadb-server
