1、首先备份Ubuntu 11.10源列表
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup （备份下当前的源列表，有备无患嘛）
2、修改更新源
sudo gedit /etc/apt/sources.list （打开Ubuntu 11.10源列表文件）
3、将下面的代码粘贴进去（“#”开头的那一行为注释，可以直接复制进文件中）
4、通知ubuntu启用新的更新源 sudo apt-get update

//教育网源
如果大家是在校大学生，可以使用校园网/教育网，就是用教育网的资源吧，中科大，兰大、厦门大学都有很多资源，尤其是支持ipv6的，那更新速度就按兆算了。
中科大：
厦门大学：
大家可以自己根据自己的版本设置一下，不一定局限于ubuntu 11.10，下面列出一些校内更新源。
