Yes, we should stay current.

We discussed the topic this Tuesday, on the stewards' meeting.
Subsequently -- two days ago --, I filed the following ticket (and CC'd
you and Bret on it):

  https://bugzilla.tianocore.org/show_bug.cgi?id=3156

It's basically a request to track down & compensate for the specifics of
the Ubuntu 20.04 breakage, and then advance to "ubuntu-latest" again.

Mike's advice was to ask you guys to work out the issues with the Ubuntu
image, interactively; mainly because (if I understood correctly) the
Azure environment may layer additional smarts onto the VM image that's
offered by <https://github.com/actions/virtual-environments>.

Also, as I said in the BZ, I'm not an Ubuntu user, so interactively
tweaking an Ubuntu installation (VM image or otherwise), to make the CI
tasks happy, is not my cup of tea. (Fedora would be different -- but
such an image is not available yet:
<https://github.com/actions/virtual-environments/issues/2307>.)

Mike, please correct any mistakes in the above.

Thanks
Laszlo
