By default, GPG Key Check is enabled for yum in Fedora Core 3 so you will see following message:
[tchung@localhost ~]$ sudo yum update Password: You have enabled checking of packages via GPG keys. This is a good thing. However, you do not have any GPG public keys installed. You need to download the keys for packages you wish to install and install them. You can do that by running the command: rpm --import public.gpg.key For more information contact your distribution or package provider. [tchung@localhost ~]$
To install GPG Key from Fedora Project:
[tchung@localhost ~]$ sudo rpm --import /usr/share/rhn/RPM-GPG-KEY-fedora
Now you should able to use yum with GPG Key Check:
