I have not used a relational database since dBASEII was current.
About a year ago I attempted to install MariaDB but didn't find tutorial
which was a close enough match to my system.
I found (and attempted to follow) instructions at:
https://www.tecmint.com/install-mariadb-in-debian/
https://www.linode.com/docs/databases/mariadb/mariadb-setup-debian/
I successfully did:
apt-get install software-properties-common
apt-get install mariadb-server mariadb-client
*BUT* both references auto-magically go to a GUI setup screen.
I'm using Debian 9 with MATE.
I don't find anything related on the Applications nor System menus.
Help please.
