Ubuntu源设置

源是什么东西就不用多说了。

 

1、在重新修改设置源时对原来的源最好进行备份：

sudo cp /etc/apt/sources.list/etc/apt/sources.list.backup（备份下当前的源列表）

 

2、修改更新源：

sudo gedit /etc/apt/sources.list（打开Ubuntu12.04源列表文件）

然后ctrl+a全选里面的原有内容并删除，把新的源（见附页）拷进去，然后保存退出。

 

3、更新源：

源变更后需要手动更新才能启用。

sudo apt-get update

说明：至少每天运行一次，而且每次修改了/etc/apt/sources.list 文件之后也必须执行一次！

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。
