在Ubuntu 12.04上安装Docker – >无法连接到守护进程

我试图在官方文档https://docs.docker.com/installation/ubuntulinux/#for-precise-1204-lts （包括重新启动）以及https：// docs之后安装docker在Ubuntu 12.04系统上。 docker.com/installation/ubuntulinux/#installing-docker-on-ubuntu

不幸的是，这最终与FATA[0000] Cannot connect to the Docker daemon. Is 'docker -d' running on this host? FATA[0000] Cannot connect to the Docker daemon. Is 'docker -d' running on this host?

 $ docker version 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] Cannot connect to the Docker daemon. Is 'docker -d' running on this host? $ docker info FATA[0000] Cannot connect to the Docker daemon. Is 'docker -d' running on this host? $ docker -d INFO[0000] +job serveapi(unix:///var/run/docker.sock) INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) FATA[0000] open /var/lib/docker/aufs/layers/df72a4d378d4e5fc20dfba9c3356f94de84278a9864e838160ae2c1e3a6c4991: no such file or directory 

不幸的是，我找不到任何类似的案例在networking上，没有先进的经验，所以我将不胜感激任何帮助:)

解决了我只需要删除图层目录。 ：/
