Title:
  do-release-upgrade daemontools-run fatal error

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

Bug description:
  It's not clear where the bug is in this, but I was doing a LTS release
  upgrade and svscan was already installed and running, but when the
  upgrade tried to set up the new one the old one was still running so
  it failed with a fatal error. Even after manually editing inittab to
  disable svscanboot and killing the old one it would always restart and
  the dpkg reconfigure would never complete successfully. Once I
  rebooted the system, then everything was working and the reconfigure
  completed without an issue.

  Here is the end of the console output for the upgrade:

  Processing triggers for libapache2-mod-php7.0 (7.0.8-0ubuntu0.16.04.2) ...
  Warning: Could not load Apache 2.4 maintainer script helper.
  Processing triggers for dbus (1.10.6-1ubuntu3) ...

  Error in function:
