Answer 1

You may come across this message/error, after installing epel-release. The quick fix is to update your SSL certificates:

yum -y upgrade ca-certificates

Chances are the above error may also occur while certificate update, if so, just disable the epel repo i.e. use the following command:

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

Once the certificates will be updated, you'll be able to use yum normally, even the epel repo will work fine. In case you're getting this same error for a different repo, just put it's name against the --disablerepo= flag.

Note: use sudo if you're not the root user.
