不确定是否有人遇到过这个问题并解决了它。我曾尝试研究过这个问题，但没有找到答案。
因此我在安装并尝试运行后收到此警告docker run hello-world。
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?. See 'docker run --help'.
我一直在尝试在 Windows 中的 Ubuntu 16.04 上正确安装 docker-ce，因为我只有 Windows 10 家庭版。不打算将我的 Windows 10 升级到任何其他版本。我尝试了几种方法。我查看了几个来源并按照说明操作，但仍然遇到该问题。

我运行sudo systemctl status docker并收到此错误：
The command could not be located because '/usr/sbin' is not included in the PATH environment variable.
This is most likely caused by the lack of administrative privileges associated with your user account.
service: command not found
我通过设置 PATH 解决了这个问题
PATH="/sbin:$PATH"

在此之后，我最终运行了sudo service docker status，结果显示 Docker 没有运行，所以我运行了sudo service docker start
我再次检查了状态，它显示正在运行。我运行docker info后得到以下结果：
