Note: There were multiple problems reported when applying the change on some installations. I particularly discourage to do this on a non-virtual machine! If you still want to give this ﬁx a try, make sure you have a snapshot/backup!
This is another remind me blog entry: If you suﬀer from above message, then you are probably using Ubuntu in a virtual machine. If so, you will need to modify initctl to simply return true using the following steps. First, you need to tell dpkg, that you are going to change the upstart package installation using:
sudo dpkg-divert --local --rename --add /sbin/initctl
Then, you need to create a dummy initctl as a link to true:
ln -s /bin/true /sbin/initctl
