Title:
  adt-setup-vm modifies cloud-init's conffile but doesn't handle dpkg
  conffile prompts

Status in autopkgtest package in Ubuntu:
  Fix Committed

Bug description:
  This

  if [ -e "$root/etc/cloud/cloud.cfg" ]; then
      echo 'apt_preserve_sources_list: true' >> "$root/etc/cloud/cloud.cfg"
  fi

  modifies a conffile, and this

  # upgrade, install some necessary packages
  chroot "$root" apt-get update
  [ "${ADT_SETUP_VM_UPGRADE:-}" = false ] || DEBIAN_FRONTEND=noninteractive chroot "$root" apt-get -y dist-upgrade

  updates the system later on. If there's a new cloud-init at this point
  we get a conffile prompt, as you can see here.

  http://jenkins.qa.ubuntu.com/job/wily-adt-setup-
  testbed/ARCH=i386,label=aldebaran-adt/63/console

  This causes the script to bomb out, and eventually resulted in

  https://jenkins.qa.ubuntu.com/view/Wily/view/AutoPkgTest/job/wily-adt-
  udisks2/ARCH=amd64,label=adt/48/console

  because -extra- wasn't installed (this happens later on in the
  script).

  I suppose we need to add force-conffoo to dpkg.cfg.d.
