几个比较常用和速度不错的ubuntu更新源

默认的中国源速度非常不错，为了保证源内软件的齐全，建议电信用户添加cn99或台湾大学的源，建议网通用户添加UBNTU官方或台湾大学的源。

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）
弹出文本后在sources.list文件中尾部添加下列内容：
ubuntu8.10的163源为：

台湾的官方源速度也相当不错，有时甚至快于内地的：
deb

gutsy-proposed main restricted universe multiverse
再加个中国电信源科技大学的源（能用速度还不 错）
deb http://ubuntu.uestc.edu.cn/ubuntu/ intrepid main restricted universe multiverse
deb http://ubuntu.uestc.edu.cn/ubuntu/ intrepid-backports main restricted universe multiverse
deb http://ubuntu.uestc.edu.cn/ubuntu/ intrepid-proposed main restricted universe multiverse
deb http://ubuntu.uestc.edu.cn/ubuntu/ intrepid-security main restricted universe multiverse
deb http://ubuntu.uestc.edu.cn/ubuntu/ hardy-updates main restricted universe multiverse
deb-src http://ubuntu.uestc.edu.cn/ubuntu/ intrepid main restricted universe multiverse
deb-src http://ubuntu.uestc.edu.cn/ubuntu/ intrepid-backports main restricted universe multiverse
deb-src http://ubuntu.uestc.edu.cn/ubuntu/ intrepid-proposed main restricted universe multiverse
deb-src http://ubuntu.uestc.edu.cn/ubuntu/ intrepid-security main restricted universe multiverse
deb-src http://ubuntu.uestc.edu.cn/ubuntu/ intrepid-updates main restricted universe multiverse
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/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～
