hours, and then in the -proposed repository.

Title:
  unattended upgrade of apt kills running apt-daily job

Status in apt package in Ubuntu:
  Fix Committed
Status in apt source package in Yakkety:
  Fix Committed

Bug description:
  [Impact]
  Causes automatic upgrades by unattended-upgrades to be interrupted if apt is configured, leaving the system in a partially configured state.

  [Test case]
  Install apt - make sure the apt-daily.service is not restarted (this systemd service runs unattended-upgrades)

  [Regression Potential] 
  It's only overriding dh_systemd_start to not be called for the service, so I don't see any possibility for regressions.

  [Original Bug report]
  This morning, I discovered that my new xenial system had attempted an unattended upgrade overnight but the upgrade was incomplete. It attempted to upgrade
  apt apt-transport-https apt-utils firefox firefox-locale-en flashplugin-installer libapt-inst2.0 libapt-pkg5.0 libgme0

  but the unattended-upgrades-dpkg.log log terminates after apt is
  configured.

  I had to dpkg --configure --pending and apt-get -f install to get apt back into working order.
  There were no errors, crashes or cores logged.

  The journal indicates that apt-daily.service stopped and restarted around the time of the upgrade, so I am assuming that is the problem (that systemd killed the update session as the result of an update to the unit files)
