前言

Ubuntu配置国内镜像源。

---

提示：以下是本篇文章正文内容，下面案例可供参考

一、配置步骤

1.查看系统代号

三种方法查看系统代号

1.lsb_release -a
2.uname -a
3.cat /proc/version 

2.修改配置文件

sudo gedit /etc/apt/ources.list
注：最好先备份
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

编辑文件，添加镜像源

注：系统代码更改为当前系统代码

刷新列表并生效
sudo apt-get update
sudo apt-get upgrade

3.补充

如果之前安装软件缺少依赖，配置镜像源后试用sudo apt --fix-broken install修复
配置完成后可以通过wine来安装Windows下的exe文件。
