+# 【Linux教程】Ubuntu Linux 更换源教程
+
+[blog.csdn.net](https://blog.csdn.net/weixin_43876206/article/details/100924378)
+
+> 因为Ubuntu自带的源已经老旧，下载速度慢，而且不稳定-
+> 本教程告诉大家如何更换Ubuntu源到国内几个比较好的源
+
+更换源步骤如下：
+
+1. 备份源列表
+
+   `sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak`
+
+2. 命令行打开sources.list文件
+
+   `sudo gedit /etc/apt/sources.list`
+
+3. 修改sources,list文件【本例更改为阿里镜像源】
+
+   #  阿里镜像源
+
+   ```bash
+   deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
+   deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
+   
+   deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
+   deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
+   
+   deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
+   deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
+   
+   deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
+   deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
+   
+   deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
+   deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
+   ```
+
+4. 更新并升级
+
+   `sudo apt-get update && sudo apt-get upgrade`
+
+ 5. 等待更新并升级完成即可
+
+【注意】更新过程中可能会有询问是否下载包的提示，输入y，按回车即可。
+
+【注意！注意！注意】更新时一定要把Linux的网络连接检查是否已经连接上网络，不然会出错，我之前试一直不成功，困了好久，才发现是虚拟机的网络没有连接。。。
+
+更新好后就可以用命令行进行安装软件或者插件了
