【记录】给Ubuntu更换源(sources.list):从原始的us.archive.ubuntu.com换个支持13.04的速度更快的源

【问题】

折腾:

【已解决】Ubuntu中安装jre结果出错:openjdk-7-jre-headless : Depends: ca-certificates-java but it is not going to be installed

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:

select best server to choose good speed server

 

2.最后选择了自己的母校的,中科大的源:

mirrors.ustc.edu.cn

finnally choose my ustc edu cn

 

3.保存:

use ustc for download from

4.再去update一下:

【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
