ubuntu改更新源(ubuntu怎么更新源)
Docker指定安装版本Ubuntu、启动以及更改源
使用Docker指定安装13.10版本的Ubuntu镜像，并运行：
最近遇到docker run不起来Ubuntu的镜像，后面才发现是自己少加了-it这个参数，运行其他的mysql之类的镜像都没需要这个参数就起来了，不太清楚为什么。
查询了一下docker run的参数也没找出来原因，还以为是-it的还有什么功能我不知道。。。。
运行起来Ubuntu的容器之后又遇到一个问题：没办法在Ubuntu里面安装任何软件，连apt-get update都没办法运行，因为：
到此就可以愉快正常地使用13.10的Ubuntu了。
关于这个老版本的Ubuntu的更新源的问题，只需要把saucy换成对应版本Ubuntu的名字就行了。
比如11.04的Ubuntu叫做代号："Natty Narwhal" ，然后那里就可以将saucy换成natty
最近一直在用docker，加深了对docker的理解，虽然还没到写出很完美的dockerfile的那种地步，但是对Docker是什么比当初有了更深一点的理解，最起码镜像和容器概念已经清楚了，补充几条命令叭。
