- 简单地讲:修改资源源地址主要是为了加快下载速度,默认的资源源地址在是境外,速度肯定没有境内速度快。
- 了解源这东西:http://wiki.ubuntu.org.cn/%E6%BA%90%E5%88%97%E8%A1%A8
- 文章的重点是页面最下面,每个版本的源地址都是不一样的,所以要懂得替换对应的版本英文名称,各个版本的英文名称大家自己找下,然后进行修改。
- 国内常用源配置方法:
- 替换过程(更换之前最好备份一下 sources.list 配置文件):
- 我以 Ubuntu 14.04 为例,使用网易源:
- 备份下:
sudo cp /etc/apt/sources.list /etc/apt/sources_20151128_back.list
- 用 gedit 编辑器打开配置文件:
sudo gedit /etc/apt/sources.list
,替换里面所有内容为下面这些内容:
deb http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse
- 更换源之后,需要在终端中执行:
sudo apt-get update
,这是必须做的,不然你后面可能会遇到 apt-get 安装会提示:未发现软件包。
