Public bug reported: I tried to do an upgrade and it looked like it was starting well, but then it complained about the missing ubuntu-minimal package. From looking at the suggested similar errors just now I suspect it's due to using mirrors.ubuntu.com for my packages
Months ago I switched to mirrors.ubuntu.com on this netbook because for whatever reason it seems to get really slow updating using any of the regular sources I have tried. For some reason it works much faster using mirrors. On the downside, I have noted a couple of difficulties attempting to pull updates from mirrors over the months, and this is probably one of them. I presume it comes down to packages not being fully distributed when the updates occur, or maybe some other glitch with the mirrors logic. I'm going ahead and noting this in case it's helpful to someone. I'm going to try the upgrade again with an "ordinary" sources.list and if I think to I'll update this bug.
