Updating FC6 x86_64

[Andrew Ritter]

I have installed FC6 x86 on a HP notebook (dual boot) and have no 
problem running updating files.  I have also installed FC6 x86_64 on a 
desktop, but have been unable to retrieve and apply any updates.

When the desktop PC boots to FC6, and I have logged on to the FC6 
desktop, I receive a message "Your system is currently not receiving 
software updates.  Please check your network connection and/or set up 
software."  After closing the error message window and manually 
initiating the updater, I get a message "Unable to retrieve update 
information."  The detail shows "Cannot find a valid baseurl for 
repo:core."  This problem is not caused by a lack of a network 
connection; I am able to connect using a browser.

Anyone had this problem or have a suggestion or solution.

Thanks in advance.
