HarmonyOS
我是按以下方式操作的：
1、查看操作系统版本
hostnamectl，查看到信息：
Operating System: UnionTech OS Desktop 20 Pro
Kernel: Linux 4.19.71-arm64-desktop
Architecture: arm642、查看UOS底层debian版本：
cat /etc/debian_version看到 基于debian 10.5
debian 10.x版本 ，代号为：buster （相关开源软件下载时，如果有对应系统和版本，可以选 debian buster 最为接近）
3、编辑 /etc/apt/source.list，添加docker的apt源
添加下面一行：
deb [arch=arm64] https://download.docker.com/linux/debian buster stable4、添加docker官方证书 (解决此问题：apt update 会失败----由于没有公钥，无法验证docker相关的签名)
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -5、更新apt源，然后安装docker
apt update
apt install docker-ce docker-ce-cli containerd.io6、检查下 docker版本：
docker version命令提示错误：“Cannot connect to the Docker daemon”
7、执行systemctl restart docker报错：
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.执行“systemctl status docker.service”，似乎没有什么有价值的错误。

但执行完，重启docker，还是一样的错误。
有热心的思友知道是什么问题吗？多谢解答！
重新开一个干净的系统，然后
再然后试试
排除变量法，看看是通信本身安装 docker 就有问题，还是你的现有的系统状态导致的
