We have created a new Launchpad PPA for the Ubuntu software presented on this site. Details can be found here: https://launchpad.net/~helfrich .
For now the repository only contains a rather silly game for Ubuntu 14.04 LTS (Trusty Tahr). Of course this is just the beginning of conquering the Ubuntu world.
The major takeaway was that it is perfectly possible to build libGDX Java projects with Gradle on Launchpad (which we will cover next).
The repository can be added as follows:
sudo add-apt-repository ppa:helfrich/ppa
