I have a quite similar problem here: whenever I must enter my password to change some system settings (e.g. in kpackagekit), the password dialog appears only for the blink of an eye and is immediately replaced by an info box saying "Failed to obtain authentication".
When starting kpackagekit from the command line, the following is printed: Application asked to unregister timer 0x38000002 which is not registered in this thread. Fix application. I'm running Kubuntu 11.04, new install (no dist-upgrade). And it used to be working, this bug appeared about a week ago on my box. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kpackagekit in Ubuntu. https://bugs.launchpad.net/bugs/758592 Title: KPackageKit fails to obtain authentication To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kpackagekit/+bug/758592/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
