I have a similar issue When the update-notifier tells me updates are available, I click the notifier icon in the panel, and the update manager starts, but the root password prompt never appears. The update manager just sits there waiting, with a "busy" mouse pointer if I hover over it.
To get the update to happen, I have to end the update manager process (it won't close normally), click on the update-notifier icon in the panel again, and on this second try, the update manager starts and the admin prompt *does* appear. -- Update Manager freezes when clicking "install updates" after having cancelled root password insertion https://bugs.launchpad.net/bugs/149435 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
