I had to install the package "packagekit" for that, which also installs
"packagekit-backend-aptcc" and uninstalls "python3-aptdaemon.pkcompat".
so it seems to switch over from apt-daemon to PackageKit mode. This
would probably be a too high impact to fix the problem.

Advantage of PackageKit mode is that pkcon is fully functional. Things
like "pkcon backend-details" and "pkcon repo-list" work now.

I tried, but my "install-printerdriver" script already failed installing
the signature.

Good news: "pkcon install openprinting-gutenprint" popped up a window
for the password and then installed the package.
