介绍一种超级简单修改源的方法.....
server版的系统都没有图形界面,用命令太过复杂,不适合新手,大家可以安装webmin后用里面的文件管理来修改etc/apt/sources.list 然后更新列表...

其实命令更换更新源也很简单！！！需要安装ssh openssh-server
然后用putty等ssh客户端登录
先把原来的更新源文件改名！
mv /etc/apt/sources.list /etc/apt/sources.list.bak
然后使用nano建立新的更新源文件
nano -w /etc/apt/sources.list
复制更新源地址，把鼠标放到putty客户端界面上点鼠标右键就粘贴进去了，然后按ctrl+x保存，提示是否更改，输入y，然后回车，就建立好了！

我开始就不会用nano和vi命令,搞了半天不知道往哪复制....
