Depending on your Linux distribution, you may need different dependencies for Wasteland 2: Director's Cut - these are generally packaged with the game's Steam or GOG releases but you may want to try getting these manually if you experience problems with your specific distro.
Wasteland 2: Director's Cut
Director's Cut only supports 64bit platforms. It should work out of the box on a clean install of Ubuntu 15.04 (assuming you have the correct video drivers installed).
It appears the Unity3D 5.0 audio back-end has switched to PulseAudio exclusively. Be sure to have it installed and the daemon/service running, if you are having trouble launching the game.
