我正在尝试在 rpi4 上安装 docker，但运行时出现此错误
sudo apt-get install docker-ce docker-ce-cli containerd.io -y
我有

怎么了 ？
答案1
我在安装内核头文件后遇到了同样的问题。如果您也这样做了，请记住重新启动 RasPi，然后检查服务状态
sudo systemctl status docker.service
我也更喜欢在 中指定主机/etc/docker/daemon.json，请参阅这里更多细节。
所以我必须删除单元配置-H中的选项systemd（/lib/systemd/system/docker.service）
不确定到底是怎么回事，但重启后一切都正常运行了。不确定这是永久修复，因为该文件可以由您的下一个apt upgrade或apt install docker-ce.
