It would be great if you could try it out on Ubuntu (I think I'm the only person that has done that so far ). I've just uploaded a binary for the 0.27.1 release of the desktop:
The binary is in http://appimage.org/ format - you should be able to double click on it and install. The screenshot below is of it running on my Ubuntu 16.04 laptop. Let me know if you have any problems!
