Ubuntu18.04软件源修改成国内镜像源

Ubuntu18.04软件源修改成国内镜像源

1. 修改sources.list文件，文件在/etc/apt目录下（操作需要root权限，记得加上sudo）

   sudo vim /etc/apt/sources.list
   

2. 添加科大镜像源，在文件最下面加上以下内容（操作之前做好备份）

   # 默认注释了源码仓库，如有需要可自行取消注释
   deb https://mirrors.ustc.edu.cn/ubuntu/ jammy main restricted universe multiverse
   # deb-src https://mirrors.ustc.edu.cn/ubuntu/ jammy main restricted universe multiverse
   
   deb https://mirrors.ustc.edu.cn/ubuntu/ jammy-security main restricted universe multiverse
   # deb-src https://mirrors.ustc.edu.cn/ubuntu/ jammy-security main restricted universe multiverse
   
   deb https://mirrors.ustc.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse
   # deb-src https://mirrors.ustc.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse
   
   deb https://mirrors.ustc.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse
   # deb-src https://mirrors.ustc.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse
   
   # 预发布软件源，不建议启用
   # deb https://mirrors.ustc.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse
   # deb-src https://mirrors.ustc.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse
   

3. 修改完成之后，保存文件。使用下面命令更新源。

   sudo apt-get update
   sudo apt-get upgrade
