Adding -www as this isn't a documentation issue but a website issue.

Agreed, it's not a bug.

This doesn't explain what the problem is, and why the above command works (or
what side effects it may have).  I don't think it's a bad idea to mention this
problem on the page but we should phrase it in such a way that it's clear what
the underlying problem is, and what the fix means.  Linking to offical RPM docs
can be a good way too?
