Title:
  Potential inconsistency due to system halt/reboot being allowed when
  package installation in progress

Status in apt package in Ubuntu:
  In Progress
Status in apt source package in Xenial:
  New
Status in apt source package in Bionic:
  New
Status in apt source package in Cosmic:
  New
Status in apt source package in Disco:

Bug description:
  [System]
  Any current Ubuntu Desktop/Server supported release (Trusty, Xenial, Bionic, Cosmic).

  [Impact]
  Package installation turns into an inconsistent state if system is rebooted in the middle of an apt install/upgrade.

  [Test Case]
  1. User1 at Ubuntu box issues "sudo apt-get upgrade";
  2. User2 at Ubuntu box issues "shutdown -r" or reboots it using the GUI;
  3. System reboots and potentially turns into an inconsistent state.

  [Remarks]
  APT should automatically inhibit system halts/reboots while packages being installed/removed. A similar behavior to what is shown by unattended-upgrades.
