Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here.
I can confirm this issue using Xubuntu Natty 64bit. When Settings is clicked and the password entered wrong, it fails silently back to update-manager. There is no indication that the attempt was even made to enter Settings. Thanks for taking the time to make Ubuntu better! ** Changed in: update-manager (Ubuntu) Importance: Undecided => Medium ** Changed in: update-manager (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/689180 Title: update-manager doesn't report authentication failure -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
