The key issue here is not being able to import apt_pkg.

This bug was fixed in the package unattended-upgrades - 0.77

---------------
unattended-upgrades (0.77) unstable; urgency=low

  * unattended-upgrade:
    - ignore md5sum "newconffile" (LP: #936870)
    - simply ignore SIGHUP instead of the setsid() magic
    - redirect ionice stderr output to /dev/null to avoid
      showing a error in a OpenVZ env (closes: #675021)
  * unattended-upgrade-shutdown:
    - be robust about import apt_pkg failures (LP: #808449), e.g.
      during upgrades
    - log when install finished to help track down LP #434835
    - do not log to syslog anymore as this *might* block and
      could cause LP #434835 and was not working in most cases
      as syslog was killed before it could log
    - log instead to /var/log/unattended-upgrades-shutdown.log
      to help track down LP #434835
  * debian/unattended-upgrades.init:
    - add Required-{Start,Stop}: $local_fs to help track down LP #434835
  * po/fr.po:
    - updated french translation (closes: #675916)
