I've had this issue for a while. The update manager window never comes up, whether I right-click on the icon and select "Update Manager", or if I run "update-manager" from a shell prompt. However, if I select "Check for Updates" or "Install all Available Updates" from that right-click menu, the progress dialog does come up showing what it's doing. If I select "Check for Updates" and it finds updates, when it finishes it updates the icon to reflect the number of available updates.
I don't know if it's relevant, but this is what I see in ~/.xsession- errors: (evolution-alarm-notify:1980): evolution-alarm-notify-WARNING **: alarm.c:260: Requested removal of nonexistent alarm! compiz (decor) - Warn: failed to bind pixmap to texture debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission denied -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1003950 Title: launcher does not show minimized update manager while clicked To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1003950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
