推荐几个国内Ubuntu更新源
-------- 本次更新于2009-11-16 -------
Ubuntu 中默认的官方源实在是太慢了，我这里只有2～3KB/s ！！！ 于是找了几个不错的更新源分享一下，方便大家找到适合自己的最快更新源。
Ubuntu更新向来很迅速，未能将每个版本的sources.list文件一一列出。请参考下表确认Ubuntu的版本（取开发代号第一个单词,如8.10的intrepid），选择好速度不错的源，然后进行简单文本替换生成所需内容：
| Release | Edition | Codename | Remarks |
|---|---|---|---|
| 2004-10-20 | Ubuntu 4.10 | Warty Warthog | 长疣的疣猪 |
| 2005-04-08 | Ubuntu 5.04 | Hoary Hedgehog | 灰白的刺猬 |
| 2005-10-13 | Ubuntu 5.10 | Breezy Badger | 活泼的獾 |
| 2006-06-01 | Ubuntu 6.06 LTS | Dapper Drake | 整洁的公鸭 |
| 2006-10-06 | Ubuntu 6.10 | Edgy Eft | 急躁的水蜥 |
| 2007-04-19 | Ubuntu 7.04 | Feisty Fawn | 坏脾气的小鹿 |
| 2007-10-18 | Ubuntu 7.10 | Gutsy Gibbon | 勇敢的长臂猿 |
| 2008-04-24 | Ubuntu 8.04 LTS | Hardy Heron | 耐寒的苍鹭 |
| 2008-10-30 | Ubuntu 8.10 | Intrepid Ibex | 勇敢的山羊 |
| 2009-04-24 | Ubuntu 9.04 | Jaunty Jackalope | 得意的怀俄明野兔 |
| 2009-10-29 | Ubuntu 9.10 | Karmic Koala | 幸运的考拉 |
| Im coming ~~ | Ubuntu 10.04 LTS | Lucid Lynx | 清醒的猞猁 |
| 未完待续... ... | |||
替换前做个副本先：
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
编辑源列表，加入国内源地址：
vi /etc/apt/sources.list

保存好后测试一下新源的速度如何：
sudo apt-get update
因为处在不同地区，换用之前先ping一下服务器看看响应时间（有些源没开ping，可以通过浏览器查看感受下速度）。我用的lupa 的源，update 了一下，更新速度基本能在200K左右，已经比较满意了。
