Sorry, on my system there was for some reason, perhaps some experiments
several months ago, installed the original PackageKit D-Bus service
("packagekit" binary package) and not the Ubuntu standard PackageKit
D-Bus service emulation using aptdaemon ("python3-aptdaemon.pkcompat"
binary package). aptdaemon was installed, giving me the impression that
it was used.
This caused the bug to occur and after returning to the standard setup
with python3-aptdaemon.pkcompat the bug went away.
So the bug is most probably in the packagekit package and most users are
still having automatic printer driver installation working, so closing
aptdaemon task ...

Title:
Regression: Cannot install signatures in Utopic any more
Status in aptdaemon package in Ubuntu:
Invalid
Status in packagekit package in Ubuntu:
New
Bug description:
In the script /usr/share/system-config-printer/install-
printerdriver.py I use package kit to add a repository to install
printer driver packages, install the signature for te repository and
finally install the driver package from the repository, to get a
secure installation and the system's update facility also updating my
printer driver package if an update gets available.
Under Trusty this works correctly, but under Utopic it stopped
working.
Under Utopic I get the following if I run the Python statements of the
script one by one at the Python prompt:
----------
till@till-twist:~$ python
Python 2.7.7 (default, Jun 4 2014, 05:21:28)

'', None, progress, None)

The signature key is from Epson. I also tried with the key
F8897B6F00075648E248B7EC24CBF5474CFD1E2F
from OpenPrinting and got the same result.
