[hoary] can't upgrade to hoary

[David Feldman]

I'd like to upgrade to hoary but don't seem to be able to. I replaced 
my /etc/apt/sources.list file with the one on the Wiki, and when I 
start up Synaptic I get a series of "Couldn't stat source package list" 
messages. I'm running Warty on a Powerbook G4.

Thanks,
