Ubuntu修改apt-get镜像地址提高下载速度

获取“源列表”

http://wiki.ubuntu.org.cn/源列表

修改Ubuntu源列表操作

查看Ubuntu

sudo lsb_release -a

返回结果 我的版本是12.04

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 12.04.5 LTS
Release:    12.04     //版本信息
Codename:   precise

然后找对应版本的源列表

备份源列表

sudo cp /etc/apt/sources.list /etc/apt/sources.list_bak

编辑源列表

sudo vim /etc/apt/sources.list

vim编辑 - 删除全部内容

:%d

杭州的可以将以下内容复制到vim编辑框中，请他的可以去源列表中找离自己附近的源
