[Bug 1649959] Re: unattended upgrade of apt kills running apt-daily job

[Chaskiel Grundman]

Right. apport wouldn't know to grab U-U logs for an apt bug. Attached.
Also below is the journal snippet that lead me to conclude that system
unit updates were responsible:

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

Status in apt package in Ubuntu:
  New

Bug description:
  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)
