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。
deb http://archive.ubuntu.org.cn/u... 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
更新完软件后，再继续设置吧。
有时你可能需要使用:sudo apt-get -f install 修复安装

因为经常会用到终端：所以把终端加到右键菜单：
sudo apt-get install nautilus-open-terminal
这就终端就在右键菜单了可以了！！

有必要学会以root权限打开文件夹
sudo apt-get install nautilus-gksu
这样右键单击文件或文件夹，选择以管理员打开！！！

查看隐藏文件是：Ctrl+ H
