ubuntu 国内最快源

在终端输入并运行
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup（备份当前的源列表，以便日後需要时恢复）
sudo gedit /etc/apt/sources.list（修改sources.list文件中源的列表）

在sources.list文件尾部添加合适的更新服务器

小贴士：只需在上述几个更新源中保留一个你测试出来下载速度最快的源就可以了，不用把所有源添加，添加完国内源之后，当然最好还是在国内源后面再添加一个官方源：
deb http://archive.ubuntu.com/ubuntu/ hardy main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ hardy-security main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ hardy-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ hardy-proposed main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ hardy-backports main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ hardy main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ hardy-security main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ hardy-updates main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ hardy-proposed main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ hardy-backports main restricted universe multiverse

保存编辑好的文件，终端执行以下命令进行软件升级。
sudo apt-get update    #这一步是更新你的源列表，换源后必须执行
（如果更新速度非常慢请更换源 sudo gedit /etc/apt/sources.list ）
sudo apt-get 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 来修复安装
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
这样终端就在右键菜单了！！
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
