Import GPG Public Key
The RPM packages are signed with a GPG key pair to ensure their authenticity. To enable the installation process to verify the packages, the public key must be downloaded and imported into the package management system.
The public key file can be downloaded from the same location as the saveset.
To import the key
Specify the key file name on the appropriate command. For example:
rpm --import ingres-10.2.0-120-NPTL-com-linux-rpm-x86_64-key.asc
