ubuntu更新源

每次升级ubuntu都有更换更新源，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、修改更新源
     sudo gedit /etc/apt/sources.list （打开Ubuntu 源列表文件）

2、查找所有的oneiric，然后全部替换为precise

或者

直接把下面代码复制到sources.list中

3、最后通知ubuntu启用新的更新源

      sudo apt-get update
