I'm not sure what is happening with my system, which is a fresh install of RHEL 7.2 only a few weeks old. It was working fine, including yum update and other yum fuctions but now gives me the following error message whenever I run yum:

yum repolist

I have already done all the actions in https://access.redhat.com/solutions/69319 and have unsubscribed, cleaned, and re-subscribed several times. It is still occurring.
