Thanks, but nope that's not the issue, I've already done both. It's just failing to do anything for some reason.

  $ do-release-upgrade -p -c
  Checking for a new Ubuntu release
  New release '18.10' available.
  Run 'do-release-upgrade' to upgrade to it.

I'm not sure if do-release-upgrade supports skipping releases, except for going from lts to lts? In other words, it might either: 16.04 -> 18.04 -> 20.04, or 18.04 -> 18.10 -> 19.04. But not 18.04 (lts) -> 19.04?

I think it should: https://askubuntu.com/a/240189

Actually, that answer seems to imply that "skipping" is just for lts>lts?

[mehrdadn]

I guess so. In my case I'm not skipping anything. It's set to normal and clearly trying to get 18.10.

Ah, I missed your original comment. I see you hit a bug with missing depencies.
