[Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 416 Requested Range Not Satisfiable"

配置docker的源的时候 报错了.

查了很久 多半是什么404然后改下源.
Yum源损坏，按照如下进行下载并替换：
先把原本的yum源重命名进行保存
然后到http://mirrors.163.com/.help/centos.html下载自己需要的版本，我这里是centos6,
按照这个说的修改没效果.

最后在:/etc/yum.repos.d下发现已经有了一个docker-ce.repo
我把这个文件删除后,重新add-repo下就ok了
