①查看自己Ubuntu的版本：

lsb_release -a

（LSB是Linux Standard Base（Linux标准库）的缩写， lsb_release命令 用来与具体Linux发行版相关的Linux标准库信息）

获取版本号后进入https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/

②选取自己版本对应的镜像源，然后进入apt文件夹

cd /etc/apt/

把之前的镜像源复制一份为001

sudo cp sources.list cources.list.001

再打开镜像源列表

sudo vim sources.list

按“a”进入编辑模式，把之前复制的镜像源粘到底下：

默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse

deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse
