Comment 40 for bug 856810

wow, are you serious, this bug should be classified as critical. Looking on google, a LOT of users are getting this error...
I couldn't get my system boot for all evening after upgrading from previous ubuntu version.
Here is how i sorted this out :

sudo mv /var/run/* /run/
sudo mv /var/lock/* /run/lock/
sudo rm -r /var/run
sudo rm -r /var/lock
sudo ln -s /run /var/run
sudo ln -s /run/lock /var/lock
sudo rm /run/dbus/*
