ubuntu更新软件源 小菜鸟上校的专栏

身为在中国的ubuntu使用者，当您费劲千辛万苦安装好ubuntu，准备开始体验一下开源操作系统的魅力的时候，您会发现有很多的软件还没有安装或者是更新，这时候千万不要急着去安装或者更新，因为您还没有更新ubuntu的软件源，这样直接安装会非常的慢，慢到让人eggache。如果您先更新了软件源，一定会事半功倍。

     按ctrl+alt+t打开一个新的终端，在里面输入：

sudo gedit /etc/apt/sources.list

然后将打开的文件中的内容全部都清空，如果您不放心的话，可以先将这个文件备份一下。然后挑选如下的一个或者几个源复制进去就可以了。
