** Description changed:

+ [Impact (unattended-upgrades)]
+ 
+  * Unattended-upgrades does not gracefully stop installing updates when
+ the system goes to hibernation potentially letting the system to
+ hibernate in a state where the system can't resume from.
+ 
+ [Test Case (unattended-upgrades)]
+ 
+  * Configure the system to have several 20+ packages upgradable by
+ unattended-upgrades. One easy way of setting this up is starting with a
+ system where packages from -security are installed but packages from
+ -updates are not and enabling -updates in u-u:
+ 
+   # echo 'Unattended-Upgrade::Allowed-Origins::
+ "${distro_id}:${distro_codename}-updates";' > /etc/apt/apt.conf.d
+ /51unattended-upgrades-updates-too
+ 
+ * Pre-download upgrades
+   # unattended-upgraded --download-only
+ 
+ * Trigger unattended-upgrades run:
+   #  service apt-daily-upgrade start
+ 
+ * Hibernate, then resume the system and watch unattended-upgrades being
+ gracefully stopped, checking /var/log/unattended-upgrades/unattended-
+ upgrades.log. There should be packages left to be upgraded.
+ 
+ [Regression Potential (unattended-upgrades)]
+ 
+  * The added hook for unattended-upgrades may block the system from
+ hibernation for 25 minutes if unattended-upgrades (or most likely a
+ package upgrades) hangs. There is a better solution proposed based on
+ systemd's inhibitor interface at https://github.com/mvo5/unattended-
+ upgrades/issues/162 .
+ 
+ [Original Bug Text]
+ 
  I added a new script in /etc/pm/sleep.d/ that worked fine before the
  upgrade to vivid. I was wondering why it doesn't work and I find out
  that /var/log/pm-suspend.log is empty, and pm-powersave.log too (last
  logs from pm-suspend were on Apr 28, when I upgraded from utopic to
  vivid.
  
  The laptop suspends and wakes fine, it just seems that no pm scripts are
  run after suspend/powersave.
