Comment 2 for bug 1806005

Note: this is a universe package

It also depends on mariadb which might be an issue in Ubuntu.
Just (trying to) install it in a fresh Disco VM fails.

It fails to set up the DB correctly on install.

And that is exactly the error we see in the log of the autopkgtest system.
