1. During the alpha/beta period of a release cycle, at a terminal, enter `update-manager -d`

What happens: Software Updater appears saying something like “New Ubuntu release '17.10' is available”. <http://imgur.com/rKy2PsM>

What should happen: Software Updater should not imply that an alpha/beta is a “New Ubuntu release”.

It’s not necessarily the case that someone using `update-manager -d` knows that it’s not *really* a new release, because they might be following out-of-date instructions.
