上个月28号，我最爱的linux 桌面发行版-ubuntu 发布了代号为 natty 的11.04版本，我也在第一时间下载，刻了盘。今天终于安装上了，感觉很棒！

用linux，最重要的就是更新源的速度，网易一直是好样的~一直是稳定和最快的。

先将其同步的ubuntu 的最新版本的源地址分享至此：

deb http://mirrors.163.com/ubuntu/ natty main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ natty-security main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ natty-updates main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ natty-proposed main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ natty-backports main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ natty main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ natty-security main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ natty-updates main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ natty-proposed main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ natty-backports main restricted universe multiverse

或者，你也可以直接下载源文件(http://mirrors.163.com/.help/sources.list.natty),重命名并覆盖掉/etc/apt/sources.list即可， 不过我本人不推荐。

速度很好~
