Description

USN-3156-1 fixed vulnerabilities in APT. It also caused a bug in unattended-upgrades on that may require manual intervention to repair.

Users on Ubuntu 16.10 should run the following commands at a terminal:

sudo dpkg --configure --pending sudo apt-get -f install

This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

Jann Horn discovered that APT incorrectly handled InRelease files. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to install altered packages.
