PkTask is more high-level, it can show Eula actions, set up Debconf
and handle GPG-keys.
PkClient is pretty low-level.

Yes: "'deb http://www.openprinting.org/download/printdriver/debian/"

Aptcc is the default PackageKit backend for Apt-based systems. It's
implemented in C++ and pretty fast.
You can install it using the packagekit-backend-aptcc package.
Aptdaemon should jump out of the way then.
The backend-details command should display the backend capabilities then.

Looks like somehow the backend does not handle 3rd-party repos properly.
(apt update runs without errors?)
