I was trying to run “docker -d” command to start docker service and install dokku by myself, but I got an error message. Any idea? Thanks!
Environment: Ubuntu+Nginx+RoR+Unicorn

Problem is solved!
This error is because the file <code>/sbin/apparmor_parser</code> is missing: <pre> 2014/06/14 02:19:41 Error loading docker apparmor profile: exec: “/sbin/apparmor_parser”: stat /sbin/apparmor_parser: no such file or directory () </pre> That command is provided by the apparmor package. Please ensure it is installed: <pre> sudo apt-get install apparmor </pre>
