redhat yum install - GPG key retrieval failed

Question

I was trying to yum install etckeeper on a Linux box. Details are as following.

the installation failed at key retrieval.

I am wondering why the key file is addressed as file:///etc/pki/. Isn't the key files should be retrieved via http?

[me@linux ~]$ sudo yum install etckeeper
[sudo] password for me:

Answer 1

Try to import manually

# rpm --import http://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6

Answer 2

You could also simply install with the command yum install --nogpgcheck {packagename}

Answer 3

You have to install the epel-release package first in order to get GPG-Keys installed:

sudo rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
