解决方案：

1. 卸载重新安装
2. 1不起作用的情况下，kill掉所有docker进程。

ps -ef | grep docker
1

3. 给docker.sock授权

sudo chown $USER:$USER /var/run/docker.sock
1

4.（可选）删掉lib文件，禁用防火墙

sudo rm -rf /var/lib/docker
sudo ufw disable

5. 重启docker

sudo systemctl stop docker
sudo systemctl start docker

5. 尝试启动hello

sudo docker run hello-world

能跑起来就没问题了
