Ubuntu 12.10也正式发布了， 安装好后第一件事就是更换源，Ubuntu网易的更新源速度很不错。
Ubuntu 12.10正式版发布下载
废话少说， 上源：
首先，备份一下Ubuntu 12.10 原来的源地址列表文件
sudo cp /etc/apt/sources.list /etc/apt/sources.list.old
然后进行修改
sudo gedit /etc/apt/sources.list
可以在里面添加资源地址，我是直接覆盖掉原来的。
下面是网上找到的一些较好的源，有大型网站的，也有教育网的，可以根据自己的情况添加两三个即可。
#网易的源（163源，无论是不是教育网，速度都很快）
