装了三次才成功。
第一次，／ 和HOME都用EXT4，选择安装软件这一步时失败。
第二次，带网线安装，在配置APT时扫描软件源不动，N久不动，又重新来
第三次／ 和HOME 都用EX3 ，放在那睡着了，自己装好了。。。。

确实很快！

ping 100次，163的要508722ms，而你上面那个只有99014ms 。（508722／99014＝ 5.137879492）

代码:

--- debian.nctu.edu.tw ping statistics ---
100 packets transmitted, 100 received, 0% packet loss, time 99014ms
rtt min/avg/max/mdev = 383.385/445.596/484.249/21.510 ms

代码:

--- mirrors.163.com ping statistics ---

网易163的更新源,速度基本在200k以上

北京联通adsl连网易的源很慢
其实“系统管理-软件源”那个画面把“从...服务器下载”选成“其他”之后，是有个自动选择最佳服务器的功能的
