The Unity team has released a testing version of Unity (Unity 5.0) that is currently available for only Ubuntu 12.04 Precise Pangolin that comes with new features. When you right-click, for example, the Dash button, a new menu is added, which is not possible in the previous version of Unity:
We will see two methods for installing and testing this new release on Ubuntu 11.10 Oneiric Ocelot as described below. Before starting the tutorial, you should bear in mind that we are not responsible for any damage that this information may cause to your system.
