As I understand  (which may be wrong), you are supposed to fully
update the existing system before you begin the release-upgrade (from
20.04 to 22.04). Once the 20.04 machine is up to date, then...

This posts suggest you should setup a local mirror, and use it for the
release-upgrade:

I've never tried it.
