由于我使用了OpenDNS,所以访问http://mirrors.163.com/ 网易的官方更新源的时候,老是会切换到60.12.227.94.(网通的那个IP).

一开始不知道,没想到会是这个原因.所以每次更新的时候,速度非常的慢.

今天突然想到了这个问题,所以研究了一下.

感觉网易考虑到了我的这种情况,所以专门建了一个电信的镜像,而且还申请了域名http://tel.mirrors.163.com .所以我就想出了下面的方法.

自己做一个更新源,只需要把以前的Sources地址,改成了电信的那个域名.

于是,所有的问题就迎刃而解了.

开心之余,把自己的Sources.list文件发布了出来,以示纪念.

(顺便说下,代码的最后一行是搜狐的,是多余的,可以删除的.本来是想用搜狐的,但是搜狐没有专门针对电信的域名,所以想法就搁浅了.)

最后,把整个过程的代码都罗列一下吧.

gedit /etc/apt/sources.list

修改完成以后.

sudo apt-get update

sudo apt-get upgrade
