我使用本指南安装docker 。我在用着

Distributor ID: Ubuntu
Description:    Ubuntu 13.10
Release:    13.10
Codename:   saucy

即使我严格按照给定的步骤操作，发出docker version命令时仍然出现错误。

Client version: 1.5.0
Client API version: 1.17
Go version (client): go1.4.1
Git commit (client): a8a31ef
OS/Arch (client): linux/amd64
FATA[0000] Get http:///var/run/docker.sock/v1.17/version: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?

我在下面提到了aleardy，但这对我不起作用。其中大多数关注Mac OS X

我怎样才能解决这个问题？

请参见下面的O / P
