前言

Ubuntu系统自带的更新源服务器在国外，下载速度一般很慢，所以更换为国内源就成为必要操作了。

一、Ubuntu 更新软件源的方法

Ubuntu 更新软件源的方法：

1、打开终端；

2、输入命令备份原有软件源文件；

3、打开sources.list文件并添加新的软件源地址；

4、输入命令更新系统软件源地址。

二、具体步骤

具体步骤如下：

1、使用快捷键【ctrl+alt+t】打开终端。

2、输入以下命令备份原有软件源文件。

cp /etc/apt/sources.list /etc/apt/sources.list.bak_yyyymmdd

3、再输入以下命令打开sources.list文件并添加新的软件源地址。

vim /etc/apt/sources.list #打开sources.list文件

PS： 新安装的Ubuntu可能没有安装Vim, 用如下命令先安装Vim：

sudo apt-get install vim-gtk

在文件末尾添加新的软件源地址，常用国内源地址如下：

apt-get update

apt-get upgrade
