[Bug 1799009] Re: Failed upgrade from Ubuntu 18.04 to 18.10

[Guy Rouillier]

I just tried to upgrade an x64 VM from 18.04 Mate to 18.10 tonight, and
it failed.  Using the Software Updater from the menu, it tells me

"The software on this computer is up to date. However, Ubuntu 18.10 is
now available (you have 18.04)."

When I click the Upgrade... button, the dialog disappears and nothing
happens.

If I run do-release-upgrade from a terminal, it tells me

"root at ubuntu64:~# do-release-upgrade 
Checking for a new Ubuntu release
Please install all available updates for your release before upgrading."
