Updating FC1 using yum

[Duke]

Hi Guys,

Been trying all day to update a clean install of FC1 using yum.

Gone tru the motions i.e saved page as in tmp, opened terminal, done the 
following

su -      #(then enter password)
cd /tmp
chown root:root yum.conf
cd /etc
mv yum.conf yum.conf.old
mv /tmp/yum.conf /etc

and type yum update. I get  loads of failover and retygrab() failed for: 
messages.
Last message on line is [Errno 4] I0Error:HTTP Error 404: not found.

Can anyone help with this?

Regards, Duke
