A) Are you using a proxy? If so, have you added the appropriate config
lines to /etc/dnf/dnf.conf (proxy IP, username, password)?

Need to double check that, I did setup a squid proxy on my desktop but I'm not sure if I have the laptop setup to use it or not... Good idea.

B) Have you tried "dnf clean all" before trying the upgrade? You may
have some bad cached data.

Nope, as soon as I switched back to my home network it worked fine. I think (A) may be the problem.

Thanks,
