My installation of sketchup under ubuntu 15.04 doesn’t work for now. Installation screen ask me to install .net framework. It downloads the framework but it’s unable to install it correctly…
During your install, did you see a screen about .NET ? If yes, how did you install it ?

I’m using the older version
i’m using sketchup 2015 and it runs perfectly smooth on my ubuntu 15.04.
.NET problems can be easily solve by installing Wine Gecko.
you can find it here
http://wiki.winehq.org/Gecko
and no longer need to disable ruby API
yup, congrats
