CentOS 7.2 - Puppet Labs PC1 Repository el 7 - x86_64 Already Installed

Recently when I try to do a normal "yum update" on one of my virtual box CentOS 7.2, I got the following error:

"The GPG keys listed for the "Puppet Labs PC1 Repository el 7 - x86_64" repository are already installed but they are not correct for this package. Check that the correct key URLs are configured for this repository."

This is due to a recent key change for the puppetlabs repo (https://groups.google.com/forum/#!topic/puppet-announce/-DiBwr51qhM).

To fix this, just download the new key and overwrite the exisitng key.

Download the correct key file:

$ curl --remote-name --location https://yum.puppetlabs.com/RPM-GPG-KEY-puppet

Verify the key:

$ gpg --with-fingerprint RPM-GPG-KEY-puppet
gpg: directory `/root/.gnupg' created
gpg: new configuration file `/root/.gnupg/gpg.conf' created
gpg: WARNING: options in `/root/.gnupg/gpg.conf' are not yet active during this run

Key fingerprint = 6F6B 1550 9CF8 E59E 6E46 9F32 7F43 8280 EF8D 349F

Import the new key:

$ gpg --keyid-format 0xLONG --with-fingerprint ./RPM-GPG-KEY-puppet

$ rpm --import RPM-GPG-KEY-puppet

Now you can enjoy your "yum update".
