GPG key problem

Hi All,

 

I installed Fedora core 2 and having some problems. First whenever I try to run up2date it gives me GPG key error (Somethink like Redhat hat public key is not in GPG key ring.. I don't remember the right message) and when I use only up2date then it ask me if I want to install GPG key and if I say yes then it takes very long time to and seems like its hung so I canncel the job.

I need to install few packages(like php-imap and perl-Digest etc.) but up2date is not working and using rpm -i command it ask for few dependencies and I don't know where can i find the dependencies.

 

Please help..

 

Thanks
