吐了，怎么搞
刚重装的系统 debian11

不是这样吗？
https://docs.docker.com/engine/install/debian/
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
Executing docker install script, commit: 7cae5f8b0decc17d6571f9f52eb840fbc13b2737
<…> 复制代码试试直接执行这行命令，看看什么原因报错
apt-get install -y -qq –no-install-recommends docker-ce docker-ce-cli containerd.io docker-compose-plugin docker-scan-plugin 复制代码

已解决，谢谢，apt upgrade

小菜鸡直接用 docker.io 就完事了，花里胡哨的
apt install docker.io 因为 docker 服务没有启动，所以在相应的 /var/run/ 路径下找不到 docker 的进程
执行 "service docker start" 启动 docker 服务，再执行 "docker ps" 就可以看到问题已经修复
