Docker not installed correctly

    root@discourse:~/var/discourse/discourse_docker# ./launcher bootstrap app
time="2015-03-05T16:38:23-05:00" level="fatal" msg="Cannot connect to the Docker daemon. Is 'docker -d' running on this host?" 
Cannot connect to the docker daemon - verify it is running and you have access

I followed the Quick Install guide. I keep getting the error above. I think docker has not been installed correctly. How do you reinstall it? When I run docker -d, I get the following

INFO[0000] +job serveapi(unix:///var/run/docker.sock)   
INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) 
INFO[0000] +job init_networkdriver()                    
INFO[0000] -job init_networkdriver() = OK (0)           
INFO[0000] WARNING: Your kernel does not support cgroup swap limit.

INFO[0000] +job acceptconnections()                     
INFO[0000] -job acceptconnections() = OK (0)    

Then it just does nothing. Please help!

Sounds like your Linux kernel is out of date. Look at updating the Linux kernel.

You need to get the command docker info working on your box working first.

Updating the Linux kernel did it! Thanks so much!
