Public bug reported: Have reported a beg regarding Update Manager today. Resolved part of the problem with advice at http://ubuntuforums.org/showthread.php?p=12027673
However, when do apt-get update, fails because it seems some websites not available. Now, Switching workspaces does not work - not in Unity not in Gnome. If I use CTl+Alt+arrow keys takes me to a WS where the panel and Unity Dash become inoperable (clicking on anything - including the shutdown icon - has no effect), and all the open Apps "disappear." If I then press the the hard shutdown button, the apps reappear, Dash and the Panel become operable again, but after a few minutes the system shuts down. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1019740 Title: Ubuntu 12.04 shuts down unexpectedly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1019740/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
