Yum Broken After 13->14 Update

[1sae]

I just ran the FreePBX 13->14 update and it mostly seems to have gone ok except for one thing. Yum Update seems broken.

# yum update
error: Failed to initialize NSS library
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   cannot import name ts

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.7.5 (default, Aug  4 2017, 00:39:18)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]

If you cannot solve this problem yourself, please go to
the yum faq at:
  http://yum.baseurl.org/wiki/Faq

No matter what I search I can’t find a solution other than one possible option, but I can’t test it out cause it’s “Subscriber Exclusive Content” on this page: https://access.redhat.com/solutions/3134931

Any help on how to fix this?

Just in case anyone is having the same issue, I found a fix:
