防止非官方源中软件包不全的问题，请在sources.list文件中尾部添加下面这个官方源。

#候补官方源

deb http://archive.ubuntu.org.cn/ubuntu-cn/ feisty main restricted universe multiverse

如果没有这个源，下面安装某些软件的时候会提示找不到，比如w32codecs ,然后 保存编辑好的文件，执行以下命令更新。

sudo apt-get update #这一步是更新你的源列表，换源後必须执行

(如果更新速度非常慢请更换源 sudo gedit /etc/apt/sources.list)

sudo apt-get dist-upgrade #这一步是更新软件

台湾源的测试可能会慢一些，耐心等一下，换源后一般下载速度都有几十K，上百K也很正常。～要是总是用几K的外源，Ubuntu也不可能在PRC混了 ～
