signature check fails doing yum update

[Rick Thomas]

Help!

I get "signature check failed" when I try to do "yum update" to 
pick up the two recent security updates.

I recently did "rpm --import /usr/share/doc/yellowdog-
release-3.0/RPM-GPG-KEY" following Matthias Saou's advice that it 
was a good idea to check these things.  ("trust but verify!"  -- 
always good advice.)


Details (including [password edited] copy of /etc/yum.conf) follow.

Has anybody had this problem before?

Thanks!

Rick

I will do the following:
[update: ethereal.ppc]
[update: nfs-utils.ppc]
Is this ok [y/N]: y
Getting ethereal-0.9.13-1.90.1a.ppc.rpm
Error: GPG Signature check failed for 
/var/cache/yum/updates/packages/ethereal-0.9.13-1.90.1a.ppc.rpm
You may want to run yum clean or remove the file:
  /var/cache/yum/updates/packages/ethereal-0.9.13-1.90.1a.ppc.rpm
You may also want to check to make sure you have the right gpg keys
