The PS3 has its own disk, so we think it's time for their own news. The UBUNTU community has ported Ubuntu 7.10 for the PS3 in time.
The kubuntu version still offers only an alternate install cd. Please give us a notice if that had changed.
As the request is high the Ubuntu server are slow and unresponsive. That's why it is a good idea to get the iso images with Bit-Torrent. We copied the small torrent files to our server so it speeds up things a little bit more.
