[Bug 1869614] Re: Missing bits noted on 16.04 to 18.04 do-release-upgrade

[Brian Murray]

The log files in /var/log/dist-upgrade/ specifically apt.log and
main.log would be helpful in determining why the package was removed.

Title:
  Missing bits noted on 16.04 to 18.04 do-release-upgrade

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  I've noted two things on a recent do-release-upgrade wherein I upgraded a 
  system from 16.04 to 18.04. It largely went well, but after the upgrade I 
  didn't see Canonical Livepatch status in my motd.

  When I looked, I noted update-motd:amd64 missing, so I installed that, but 
  that still didn't make my motd show Livepatch status. A bit of searching noted 
  that /etc/cron.daily/ubuntu-advantage-tools runs to update 
  /var/cache/ubuntu-advantage-tools/ubuntu-advantage-status.cache, and evidently 
  that hadn't happened.

  That would be a very reasonable thing to run on boot, not just daily out of
  cron. I'd think that on boot, perhaps as part of the livepatch service 
  start-up, would be the most reasonable place to do that, in addition to the 
  cron job.

  It's as yet unclear why update-motd was missing. I didn't see spoor from the 
  do-release-upgrade in /var/log/apt/history.log, which is where I'd have 
  naively expected to see it.
