Another up2date error

[leam]

I have a stock FC1 install and running up2date -u gives the following 
error twice:


######

     raise ValueError, "CRC check failed"
ValueError: CRC check failed


####

Is the CRC error a load issue somewhere? Is this an indication, along 
with the other up2date/yum errors that I need to find a mirror? Is there 
a mirror list somewhere? Didn't see one on the Fedora site.

ciao!
