Ubuntu 12.04更新源地址列表更改方法

Ubuntu 12.04更新源地址列表更改方法

每次升级Ubuntu都有更换更新源（gengxinyuan），其实更新源地址不必上网找，直接自己更改就可以了。更新源的地址基本上是这样的：

deb http://ubuntu.srt.cn/ubuntu/ oneiric main universe restricted multiverse

这个是Ubuntu 11.10的更新源地址，其中 oneiric就是ubuntu 11.10的开发代号，所以我们只需要将电脑中的更新源列表里的开发代号替换为Ubuntu 12.04的开发代号就可以了，用ctrl+F查找出来全部替换就可以了。因此以后再换版本就不用自己上网搜索更新源了。

Ubuntu 12.04的开发代号是Precise Pangolin，译为精确的穿山甲。所以只需将oneiric替换为precise即可

1、首先备份Ubuntu 11.10源列表
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup （备份下当前的源列表，有备无患嘛）

2、修改更新源
sudo gedit /etc/apt/sources.list （打开Ubuntu 11.10源列表文件）

3、用ctrl+F查找所有的oneiric，然后全部替换为precise

4、通知ubuntu启用新的更新源 sudo apt-get update 

//当然如果你比较懒，或者是全新安装的ubuntu，那你可以直接把下面的代码复制到sources.list中

//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。
