Thats odd. Running gksu should still ask you for a password since you are asking for root privileges. Anyway, since it runs under sudo but not under your user account, I am betting its a local user error and not a system wide bug. Lets try removing the update-manager and putting a fresh one in.
1) sudo apt-get autoremove --purge update-manager 2) sudo find / -name *update-manager* > ~/Desktop/Find1 The second command will create a file on your desktop. Attach it in here so I can look at any residual files left over from the autoremove command. Thanks. *Don't reinstall the update-manager just yet* -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/769800 Title: update-manager fails when asking the admin password -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
