Can you try, from a command line, running "gksu synaptic"? This should attempt to bring up the same password entry dialog, then load synaptic package manager.
If this fails in a similar way, then the problem is with gksu (i.e. the password entry dialog itself). -- update tool does not show passwort screen - no updates possible https://bugs.launchpad.net/bugs/243937 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
