hours, and then in the -proposed repository.
Please help us by testing this new package. See

enable and use -proposed. Your feedback will aid us getting this update
out to other Ubuntu users.
If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed. In either case, details of your testing will help
us make a better decision.

Title:
pkservice.py crashed with AttributeError in __init__(): 'module'
object has no attribute 'MainLoop'
Status in HP Linux Imaging and Printing:
Fix Committed
Status in hplip package in Ubuntu:
Fix Released
Status in hplip source package in Vivid:
Fix Committed
Bug description:
If an HP printer needs HPLIP with HP's proprietary plug-in (firmware
files for printers, proprietary driver code pieces for printing and/or
scanning) the automatically initiated installation of the plug-in
fails and causes crash reports, leading to crash report pop-ups and
non-working printing and scanning functionality. The problem is caused
by the switchover from Python2 to Python3 in Vivid, especially also
that the Python3 executable is named "python3" and not "python".
If the crash happens shortly before shutdown or reboot the pop-up can
appear right after log-in.
[Impact]
All Vivid users who use a printer or multi-function device which needs
HP's proprietary plug-in get crash pop-ups and their devices will not
completely work or not work at all.
[Test Case]
Connect an HP printer or multi-function device which needs the plug-in
(for which models see this bug report and the numerous duplicates) and
set it up. As soon as the plug-in gets downloaded and installed, crash
reports pop up, and the devices functionality which needs the plug-in
will not work as plug-in installation does not complete.
The proposed package solves the problem.
To test without having an appropriate printer, simply run the command
hp-plugin
in a terminal window. With the current package it will fail as
mentioned, with the proposed package plug-in installation will
succeed.
[Regression Potential]
Very low. The patch is trivial and it affects only users who need the
plug-in. All users of other HP printers or non-HP printers are not
affected.
