Error installing Guitarix from KXStudio repos Kubuntu 16.04

[warkus]

Hi all, I am getting an unmet dependencies error when attempting to install Guitarix from KXStudio repos on Kubuntu 16.04. I installed Kubuntu 16.04 beta 2 and have upgraded along the way until now. Other programs have installed and work fine such as Cadence, Ardour, Qtractor etc. I see at least one other 16.04 user has installed the latest guitarix from KXStudio and was wondering if my system is somehow messed up, or if anyone knows a few commands to get me out of trouble? Synaptic doesn't show any broken packages... Any help is appreciated, I just want to rock out with my home made strat using the flashy new Guitarix .35

Wow, don't I feel like a noob! I thought I had already installed the gcc5 repo, but obviously not
