There seemed to be an SSL CA cert problem on my end.

Chrome browser is working ok.

I tried links lynx and elinks and they all couldn't connect with SSL errors.

I recently configured msmtp mail(mta) and may have inadvertently mess up in '/etc/pki/tls/certs/'


$ rpm --query --file  /etc/pki/tls/certs/ca-bundle.trust.crt

$ sudo yum reinstall ca-certificates-2011.78-1.fc16.noarch
  ca-certificates.noarch 0:2011.78-1.fc16

@macroron Could you please attach your complete mirrorlist lines?

After going through these steps and changing my .repo files back to the original, the error comes back...

Please don't rename the title to "Solved" unnecessarily. Just mark the answer you prefer and that will be enough to note that this question has been answered to your satisfaction.

In errors like this, I always like to use urlgrabbers debug mode:

URLGRABBER_DEBUG=1 yum check-update

and look for lines with error in them. This will usually tell you what the exact issue is with downloading the mirrorlists.
