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：
