6.0 Alpha Won't Install

I have several partitions on my drive, and I currently have Kubuntu and CrunchBang installed. I'd like to follow the development of Trisquel 6.0, so I downloaded, burned, and booted the 10/8 alpha.

Regretfully, ubi-portman failed, and I was unable to continue. Before it failed, a bunch of folder windows opened and generated error messages about not having permission for /tmp folders.
