GPG keys problems occurred when installing software using yum in Fedora

When releasing an RPM file, the software developer adds a digital signature to the file and releases the public key used to verify the digital signature. When you use RPM to install software, RPM first verifies the digital signature of the RPM file based on the existing public key in the system. GPG keys is the public key.

Problem: Public Key for *. rpm is not installed

The system does not have a public key that can verify the RPM digital signature.

1. Install the existing GPG Public Key. Under/etc/pki/rpm-GPG/, you can

   Sudo rpm -- import/etc/pki/rpm-GPG/RPM-GPG-KEY *

   Install all of them directly...

2. If it still doesn't work, you can specify parameters without checking the digital signature.

   Sudo Yum-y install * -- nogpgcheck

Problem:

The GPG keys listed for the "fedora 14-i386" repository are already installed but they are not correct for this package.

Check that the correct key URLs are configured for this repository.

When the public key under/etc/pki/rpm-GPG/is installed, all are import failed

I don't know what's going on

Only -- nogpgcheck is supported...
