Oops, "Shutdown".

"This script is the backend  for  the  APT::Periodic::Unattended-Upgrade
       option and designed to be run from cron (e.g.
via /etc/cron.daily/apt)." -
http://manpages.ubuntu.com/manpages/yakkety/man8/unattended-upgrade.8.html

This means that masking the systemd unit is useless.

Anyway, there are two files in /bin:

/usr/bin/unattended-upgrade
/usr/bin/unattended-upgrades (just a link against /usr/bin/unattended-upgrade)

So running

  sudo dpkg-divert --add --rename --divert /usr/bin/unattended-upgrade.real /usr/bin/unattended-upgrade

should make it impossible to launch it.
