[orca-list] updating to ubuntu guttsy

[mike Reiser <metalhead1009000 gmail com>]

I'd like to try out the accessibility emprovements in the latest beta of 
ubuntu guttsy.   I modified the /etc/apt/sources.list and changed every 
occurence of the word feisty to guttsy so now the url looks like 
http://archives.us.ubuntu.com/ubuntu guttsy.  I didn't modify anything 
else.  However, when I go into terminal and run sudo apt-get update, it 
gives me 404 errors.  Is there suppose to be a space between ubuntu and 
guttsy or - or what?  I tried searching for documentation on this but 
couldn't find any probably because we aren't at final release.  Any help 
would be great.  Thanks,

Mike
