教育网源
如果你是在校大学生，可以使用校园网 / 教育网，就是用教育网的资源吧，尤其是支持 ipv6 的，那更新速度就按兆算了。

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。
ubuntu14.04怎么更换源
方法一：图形界面操作更新源
1
点击右上角的”搜索“图标，在搜索框中输入update，在显示的应用列表中，点击”SoftwareUpdates（软件更新）“。
2
在弹出的”SoftwareUpdates“窗口中，选择”Ubuntu Software“，你可以看到”Download from（下载源）“是”Server for United States(美国服务器)“。点击”Server for United States“下拉菜单，选择”Other...（其他）“。
3
在弹出”Choose a Download Server（选择下载服务器）“窗口中向上拉，找到China（中国）,然后，选择中国的服务器，这里可以选择教育源，网易、阿里等等。（我在这里选的是163（网易）的），然后点击”Choose Server（选择服务）“按钮。
4
然后，弹出”Authenticate（认证）“窗口，输入系统密码（ubuntu上由于安全性安装软件，需要输入密码），然后点击”Authenticate（认证）“按钮。
5
此时，你会发现”SoftwareUpdates“窗口中的”Download from（下载源）“已经变成你设置的中国源。点击”Close(关闭)“按钮。
6
然后，会弹出一个提示,大概意思是”安装软件和更新添加的源或修改源，必须要重新加载可用软件的信息“，点击”Reload（重载）“按钮。进入”Updating cache(更新缓存)“界面，等待更新完过后，下载源就真正变成中国的了。以后下载东西就更快了。
