Docker踩坑

Ubuntu16.04安装Docker，无法打开
安装结束报错为

Processing triggers for ureadahead (0.100.0-19) ...
Errors were encountered while processing:
 docker-engine
E: Sub-process /usr/bin/dpkg returned an error code (1)

尝试打开

root@hzy-pc:/home/hzy# sudo service docker start
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

使用命令查看

root@hzy-pc:/home/hzy# systemctl status docker.service

网上方法都试过了，很无语，，，，

俩月后来更新，这个好像当时智障给国内docker仓库镜像写错了有关
daocloud那个，感觉不太好用？ustc的挺不错的
