Docker images,info,-d and other commands to solve the error _docker

First, the discovery of problems

Landlord regardless of input that command, have appeared:

Ii. Solutions

As well as similar errors, even the docker version command is an error, the landlord began looking for, found a lot of things, the results found that no one can do, the last landlord to use such a command:

Add the following content to the file:

That's all. I don't know what to do. It's really amazing.

Landlord quickly used a bit

syx@syx-vb:~$ Docker version 
client version:1.6.2 
client API version:1.18 go 
version (client): go1.3.3 
Git Commit (client): 7C8FCA2 
Os/arch (client): linux/amd64 
server version:1.6.2 
server API version:1.18 go 
version (server): Go1.3.3
   git commit (server): 7C8FCA2 

Good magic, finally can, the landlord quickly Docker upgrade to the latest version.

$ sudo add-apt-repository ppa:docker-maint/testing 
$ sudo apt-get update 

Landlord so on the line once, and then the landlord began to find reasons, the landlord asked to ask, others said in Ubuntu install a devicemapper

The landlord uses the following commands:

It's still not working.

root@syx-vb:~# Service Docker Restart  
root@syx-vb:~# Docker version  
root@syx-vb:~# Docker version 
Client Version:1.7.0-dev 
Client API version:1.19 Go 
version (client): go1.4.2 
Git commit (client): 9234460 
OS /arch (client): LINUX/AMD64 

Landlord English is not good, do not understand what meaning, then ask.

Someone told the landlord docker -d to use to see:

root@syx-vb:~# docker-d 
info[0000] listening for HTTP on Unix (/var/run/docker.sock) 

Don't understand, then ask the great God!!!
The great God said to the/var/lib/docker under the Devicemapper clear off, the landlord a look:

root@syx-vb:/var/lib/docker# ls 

And there's this directory, so use:

Then:

root@syx-vb:/var/lib/docker# Docker version 
client version:1.7.0-dev 
client API version:1.19 go 
version ( Client): go1.4.2 
Git commit (client): 9234460 
os/arch (client): LINUX/AMD64 

Why Still not!!

This time the landlord restarted a bit Docker service, incredibly good.

root@syx-vb:/var/lib/docker# Service Docker Restart
