up2date/yum troubles

[mmarkiw at speakeasy.net]

Hi all,

I'm having some problems getting my FC1 system updated with all the related patches available.  When I first set up my box I made the intial changes to the /etc/sysconfig/rhn/sources file to point at these:

yum fedora-core-1 
> http://download.fedora.redhat.com/pub/fedora/linux/core/1/i386/os/
> yum updates-released 
> http://download.fedora.redhat.com/pub/fedora/linux/core/updates/1/i386/
> #yum updates-testing 
> http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/1/i386/

instead of the default values and it worked fine for quite a while.

Now, when I try to run the update agent, I get messages saying that there isn't a GPG signature or that the GPG signature doesn't match.  It takes forever to download and frequently hangs, forcing me to kill the application.  Does anyone have any suggestions for fixes or at least more things for me to check?  Its killing me to run a box with unpatched software.

Thanks,
