Ansible
The code server uses Ubuntu 14.04 LTS.

While the LTS provides stability, it means that some packages get left behind on old versions.

Case in point is ansible. The version in the Ubuntu repos is 1.5.4, which is too old for our needs.

The following allows us to install the latest version (1.8.4 at time of print).

sudo apt-get install software-properties-common
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update
sudo apt-get install ansible
