Error installing MariaDB on Ubuntu 16.04 LEMP
Have a relatively default latest Ubuntu server (16.04) running LEMP.
Unlike all the other wonderful step by step tutorials the page here: https://www.digitalocean.com/community/tutorials/switching-to-mariadb-from-mysql simple said to uninstall (even though commenters said not necessary) and then install and provided a link another website without any further details. None the less, installed following those instruction.
When installing using the instructions on the MariaDB site: https://downloads.mariadb.org/mariadb/repositories/#mirror=digitalocean-nyc&distro=Ubuntu&distro_release=xenial--ubuntu_xenial&version=10.1 all steps work except the last when it actually tries to install.
$ sudo apt install mariadb-server

I assume this must be a common issue since I'm using the latest stable Ubuntu and using the latest stable MariaDB. What am I missing?
