For the record, running "apt install --reinstall containerd" is enough
to reproduce it. It seems fine after restarting it. Investigating...

Title:
  docker stopped when containerd updated

Status in unattended-upgrades package in Ubuntu:
  Confirmed

Bug description:
  When containerd was updated in my bionic instance it stopped docker
  then stopped containerd. When it was done updating containerd it
  brought it back online. docker stayed stopped.

  2020-04-03 06:20:32,973 INFO Packages that will be upgraded: apport
  containerd python3-apport python3-problem-report

  An eoan installation that didn't have this problem had this line:
  2020-04-03 06:06:01,612 INFO Packages that will be upgraded: apport python3-apport python3-problem-report

  So the main difference is that containerd was updated.

  At the end of this systemctl --all reported docker as:
  docker.service                 loaded    inactive dead
  and containerd as:
  containerd.service             loaded    active   running
