I thot I was facing this too, but on 11.10. Turns out is was just logging stopping at that point.
I found that stopping network-manager (https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/875959) allow shutdown/restart. Whether that is due to the wrong ethernet driver being used (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/779040) or not I don't know yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/434835 Title: unattended-upgrades hangs system on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/unattended-upgrades/+bug/434835/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
