  BEGIN failed--compilation aborted at /usr/bin/deb-systemd-helper line 85.
  dpkg: error processing archive /var/cache/apt/archives/libvirt-daemon-system_1.2.8-3_amd64.deb (--unpack):
   subprocess new pre-installation script returned error exit status 2

The libvirt-daemon-system package is using non-essential functionality
in a preinst script without a pre-dependency. Policy 6.5:

  The package will not yet be unpacked, so the `preinst' script cannot
  rely on any files included in its package.  Only essential packages
  and pre-dependencies (`Pre-Depends') may be assumed to be available.
  Pre-dependencies will have been configured at least once, but at the
  time the `preinst' is called they may only be in an "Unpacked" or
  "Half-Configured" state if a previous version of the pre-dependency
  was completely configured and has not been removed since then.

(I'm not quite sure if even a pre-dependency would be safe, see the
last sentence above.)
