You can turn off the use of GPG signatures in up2date.  On a RH9 box, 
run up2date --configure and select option 29:

29. useGPG             No

I'm sure this is fairly close to the Fedora release.  If you're using 
yum at some point, this setting is taken care of in the yum.conf file. 

If you really want to use them, then I'd suggest checking your 
up2date-keyring, specified via the gpgKeyRing in up2date located in 
/etc/sysconfig/rhn/.
