The TravisCI addon of Mariadb 10.1 is broken. This was working a few days ago.

Please link to the build and a previous successful build.

I can reproduce the issue.

This is a failing build with MariaDB 10.1: https://travis-ci.com/PowerKiKi/mqueue/builds/125514256#L187
And this is a successful build with MariaDB 10.3: https://travis-ci.com/PowerKiKi/mqueue/builds/125780415

Looks like the apt package dependencies are different between versions 10.1 and 10.3.

From what I can see from http://nyc2.mirrors.digitalocean.com/mariadb/repo/10.3/ubuntu/dists/xenial/main/binary-amd64/Packages, installing mariadb-server package is useless and is causing the installation error.
“This is an empty package that depends on the current “best” version of
mariadb-server”.
So if you are installing it, you won’t be able to install anything but that “best” version at the same time.
