Thanks to all for getting this patch in place. The bug appears to be resolved.
A few comments: I installed hplip-3.15.4.run as per the conversation above with TomasHynk. When this fix was released, I wanted to uninstall what hplip-3.15.4 installed and revert to the standard Ubuntu stack. This http://hplipopensource.com/node/188 explains how to uninstall. I followed it exactly and then reinstalled hplip via synaptic. However it seems that the files in /usr/share/hplip and /etc/hp were removed by the uninstall process given above and not re-installed by synaptic. So I reinstalled hplip-3.15.4, made sure everything was working, then deleted my two printers, uninstalled it again as per the instructions above EXCEPT I did not do the sudo rm's, and then installed hplip via apt-get. But hp-setup does report that it is ver. 3.15.2 so I am most of the way there. As I said, things now seem to be working, though I'm not completely convinced I have fully reverted! Thanks again to Till and others who got the show back on the road. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1422004 Title: pkservice.py crashed with AttributeError in __init__(): 'module' object has no attribute 'MainLoop' To manage notifications about this bug go to: https://bugs.launchpad.net/hplip/+bug/1422004/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
