Ubuntu 12.04更新源

1.sudo cp /etc/apt/sources.list /etc/apt/source.list.bk

sudo gedit /etc/apt/sources.list

编辑你的源列表，将原来的内容全部删除，添加下面列表中最适合你的源(163,台湾的速度比较快)

2.sudo apt-get update 更新源列表信息

可以在运行“sudo apt-get update ”时查看一下错误信息，把不能连接的源删除再重新运行

“sudo apt-get update ”。

3.sudo apt-get upgrade 升级

或者用ubuntu自带的更新管理器升级也可

//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，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。
