How do I fix MariaDB error?
Solution 1: Try to restart the MariaDB service and check whether it's working.

sudo systemctl start mariadb. Refresh the Koha page.
ls -a /var/run/mysqld.
sudo chown mysql:mysql /var/run/mysqld/
sudo systemctl restart mysql.
sudo apt purge "mariadb*" -y.
sudo apt-get install mariadb-server mariadb-client.
