Title:
  Fix FTBFS of aptdaemon 1.1.1 for Saucy

Status in “aptdaemon” package in Ubuntu:
  New

Bug description:
  The functionality to automatically download and install printer
  drivers in system-config-printer does not work any more in current
  Saucy. The problem is with PackageKit. After a hint from xnox on IRC I
  have installed aptdaemon 1.1.1 from

  https://launchpad.net/ubuntu/+source/aptdaemon/1.1.1-0ubuntu1

  (adding "DEB_BUILD_OPTIONS=nocheck" to debian/rules to override the
  failing tests) and  with this version the driver package installation
  of system-config-printer works.

  Can you fix the aptdaemon 1.1.1 package so that it makes it into
  Saucy? I am very grateful if automatic printer driver download will
  work in Saucy.

  The problem seems to be an API compatibility failure when trying to
  add the GPG key:
