Yeah, I thought of that as well at first, and it's definitely
something that we need to fix in lcitool. I'll post a patch later.

That said, in this case the problem can't be solved by simply
inverting the commands: from the output above, you'll see that the
signing key for Fedora 35 is already present on the system; however,
since the RPMs that are currently in the Rawhide repos are still
signed with the Fedora 34 key, we need to convince dnf to use the
latter for validation. That's what the hack in this patch does.
