I got the same errors as Harald after trying the above. It was still very slow to shutdown and sometimes didn't shutdown at all.
The only way I could previously get it to shutdown reliably was with a "sudo shutdown -h now". I have now found if I remove the network manager it completely fixes it. I now have no errors and quick shutdown. sudo apt-get remove network-manager If I re-install the above network manager, the problem comes back. So that is definitely the cause in my case. I have installed "wicd" as a replacement network manager. I did this before removing the Ubuntu supplied network manager. I am using 11.10 that has been upgraded from 11.04. I have wired ethernet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/869635 Title: long delay at shutdown/reboot - network-manager doesn't close correctly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/869635/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
