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

[Guy Rouillier]

[UPDATE] I have dual boot on this computer, and also have Ubuntu Mate
18.04 running as a bootable OS.  I just tried to upgrade that
installation, and it fails in exactly the same way.  I only recently
installed that instance, so it's a very simple installation at this
point (unlike the VM which I've used for several years and installed
numerous packages, including PPA.)  So there appears to be a general
problem in this upgrade path.
