I first saw this after the updates to Lubuntu 14.04 yesterday morning March 13 10:15GMT. In my case it is only the Lubuntu 32bit system that is affected, not Xubuntu or Ubuntu both of which are 64 bit.
I posted the problem to Ubuntuforums http://ubuntuforums.org/showthread.php?t=2210892&p=12956114#post12956114 and gave my workaround for the problem, ie changing the line Exec=synaptic-pkexec in /usr/share/applications/synaptic.desktop to Exec=gksudo synaptic but this very much a workaround which should not be needed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1288786 Title: pkexec does not launch graphical authentication To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/policykit-1/+bug/1288786/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
