I think this sources.list is not working anymore. I've just installed MacBuntu on a spare PowerBook G4 5,8 that I rebuilt from parts for Linux purposes. Admittedly it works great out of the box (pretty much everything is detected hardware-wise except for brightness and other keyboard controls which you describe in your README.txt). So many thanks for this tweaked Linux version for our ancient Macs! Now I tried to update the system but it wouldn't le me do that since I'm getting 404 errors (sources.list has been edited). Any ideas what I can do or are there any other mirrors for PowerPC? Thanks!
