I have the same problem, using Xenial 16.04 (X64).

Seems  solution is to install python3-aptdaemon.pkcompat, which removes
packagekit.

'sudo apt-get install python3-aptdaemon.pkcompat'

dpkg: packagekit: dependency problems, but removing anyway as you requested:
 packagekit-tools depends on python3-aptdaemon.pkcompat | packagekit-system-interface | packagekit (= 0.8.17-4ubuntu6~gcc5.4ubuntu1); however:
  Package python3-aptdaemon.pkcompat is not installed.
  Package packagekit-system-interface is not installed.
  Package packagekit which provides packagekit-system-interface is to be removed.
