Can anyone let me know how to get it fixed.

What version of Red Hat is your linux box running?

2.6.32-504.el6.x86_64
Red Hat Enterprise Linux Server release 6.6 (Santiago)

Let's see a list of your repositories:

Error: Cannot retrieve repository metadata (repomd.xml) for repository: epel. Please verify its path and try again

I found this stack exchange post regarding the above error string: https://stackoverflow.com/questions/267 ... y-its-path

Try the following:

You just needed to update ca-certificates package. Before that just disable all repos with https that are failing. That's why sollution with commenting mirrorlist or using http instead https would work also.

For example if you need to disable only epel repo:

yum --disablerepo=epel -y update ca-certificates

This will also help wget, curl, and anything else that uses SSL certificates.
