【问题】
折腾：
期间，发现，虽然之前换的163的源：
【记录】给Ubuntu更换成163的源（sources.list）
速度是快了，但是却会导致：
由于目前（2013-08-12），163的源，不支持13.04，最高只支持12.04，导致我在安装openjdk时出错，无法安装。
而最后是换到了原始的，us.archive.ubuntu.com，才解决了此问题的。
所以，现在要去：
换个，支持13.04的，且链接速度，比默认的us.archive.ubuntu.com要快的源。
【折腾过程】
1.通过Select Best Server，自己去找速度快的：
2.最后选择了自己的母校的，中科大的源：
mirrors.ustc.edu.cn
3.保存：
4.再去update一下：

Done crifan@ubuntu:openjdk-7-7u25-2.3.10$
5.然后再去确认一把，是否可以正常安装openjdk：
然后狂爽，速度达到2,3MB/s，哈哈哈：

【总结】
至此，终于：
将Ubuntu的源，从默认的us的，换成了ustc的；
且正常安装成功了jdk了：
sudo apt-get install openjdk-7-jre-headless
