Re: Problems installing MariaDB

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

This is not strictly necessary. software-properties-common provides the program "apt-add-repository" which, in turn, is only required if you're installing packages from a different repository (particularly Ubuntu PPAs). However, 'mariadb-server' is in all current versions of Debian (jessie to sid), so you're best to stick with the Debian version.

  apt-get install mariadb-server mariadb-client

*BUT* both references auto-magically go to a GUI setup screen.

This is part of the magic of dpkg called "debconf". "debconf" is a system whereby packages can ask a user questions at installation (and removal) time and configure themselves accordingly. debconf comes with a series of frontends depending on the user's preferred method of interaction. What you see in those tutorials (the grey boxes with the blue background) is the frontend called "dialog". There are more basic fronends (Noninteractive - answers must be provided in a pre-existing text file, Readline - questions are asked by a simple plain-text prompt and Editor - use your favourite text editor to provide answers) as well as more glitzy ones (Gnome and KDE).

Debconf uses a fallback method, too. If you select, say, Gnome as your frontend, but are updating outside of an X environment, then debconf can fallback to 'dialog' and, if you're installing on a dumb terminal (say, your computer is so badly off that you're installing over a serial line) it can fallback to readline.

Now, if you're not getting these prompts, then the best place to start is by choosing (again) the configuration of debconf. Run:

 # dpkg-reconfigure debconf

and, hopefully, you should first be asked what your preferred frontend is. Next, you will be asked to set the LOWEST priority of question you want to see. Critical prompts are for questions that might break your system (e.g. I would imagine that systemd's take over of init was couched as a critical question). High importance are for questions that the package needs to know the answer to (but if you don't provide that answer, the service probably won't run) and Low importance questions are the sort that 99% of people will just skip over.

Finally, once you've reconfigured debconf, try running:

# dpkg-reconfigure mariadb-server

and you should get prompted for the default password.

I'm using Debian 9 with MATE.
I don't find anything related on the Applications nor System menus.
Help please.
