We’ve just tried booting Ubuntu 13.04 PPC but it spazzed out during boot.
We’ve now got Lubuntu 14.04 booted to the live environment and will try to perform an install now
UPDATE – Lubuntu failed to install. The installer ran but then seemed to crash out.
I’ve decided that the best option will be to try and install Ubuntu server for PPC and then add a front end to it afterwards.
UPDATE2 – Ubuntu server is going on fine at the minute.
