Cannot upgrade a fresh install of bionic

[Kevin O'Gorman]

I did a fresh install of Xubuntu 18.04.4 from a CD-ROM, updated all packages, and immediately tried do-release upgrade to get to Bionic. I know, it seems odd to do that, but I have reasons I'll report in a separate bug. Anyway, there was absolutely nothing else done besides these things.

I did all my stuff under script, and I'm attaching the scripts. There are two because I had to do a reboot after the upgrades and before the do-release upgrade.
