```
    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
root@discourse:~/var/discourse/discourse_docker# 

```

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 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Sounds like your Linux kernel is out of date.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!
