public key import

RPM files available are signed with a private key, as part of checking its genuines. Like in RSA algorithm, you need to use public key to check the package genuines. For this case, when you try Software installer, it sometimes fails for package doesnt pass the genuine test. How to move ahead, import the public key.

Usually, find for the public key , as came with your linux distro and import it. ( => find / -name “*GPG*” and then import with rpm –import *GPG* )

Note: hope you got a copy of the distr cd’s with you.
