This is on CentOS 8, but since there isn't a group for it yet, I'm posting it here.
When I login I get that wonderful box in the lower right saying, "Available updates - SECURITY ISSUE, CWP found 1 available yum/rpm updates for your server, click here to check it."
I click on it, and then the update list is empty.
I'm guessing this is a bug, since CentOS 8 uses DNF, and not YUM anymore.
