Looks like your database isn't available. First check if it is running by using "systemclt status mariadb". In best case you only need to start it by using "systemctl start mariadb".

Failed to connect to the database:

DB is not available. Please check that it is running.

As this seems to be a setup issue I would like to ask you to raise your question in the forums: https://help.nextcloud.com
