Ubuntu 添加教育网更新源【转】

教育网一般使用中科大，上交或者成都电子科技大学的源再加上台湾官方源(可选)：

修改你的更新服务器列表。请在终端中执行下面的两条命令：

首先备份一下更新源地址配置文件：
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup（备份）

在终端输入 sudo gedit /etc/apt/sources.list

更改文件 /etc/apt/sources.list，换成下面任意一组，保存之后，执行下面的两条指令来更新系统信息：
sudo apt-get update #
sudo apt-get upgrade
成功
