epel-release package and hit with following error:

The GPG keys listed for the "CentOS-7 - Extras" repository are already
installed but they are not correct for this package.
Check that the correct key URLs are configured for this repository.


 Failing package is: epel-release-7-5.noarch
 GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7,
