You have to add a flag to get off of the LTS brach, Maybe '-d"? Both 16.04 and 180.04 are LTS. the next LTS will be 20.04

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.
