Given there's confirmation of some issue with the repositories,
I'm wondering where it should be reported for fixing. It looks like
the repo has been set up but not copied/moved to the appropriate
server or location, i.e., cloud rather than cran. My guess is that
there are some users struggling and thinking that they have made an
error. The msg on my machine concerned the Release.key file, but
the reality is a missing repo. Once I recognized that, it didn't
take too long to get R4.0 running.
