The changes consequent on hardening of the rpm update mechanism were
poorly handled.
The changes consequent to upgrading the updateVM to fedora-33 were
warnings, and the solution was signalled in the warning message. 
(see 'gpgcheck' in dnf.conf(5) for how to squelch this message)
Very few users seem to have a) read that message, or b) tried to do what
it said.
You have to look at the manpage in the updateVM (since that is where the
warning is coming from) and apply the solution in dom0. This isnt
intuitive unless you know about the Qubes dom0 update mechanism.
