我使用的是Ubuntu 18.04 (运行的是模拟的Windows)，完全是个新手。我按照以下步骤安装了Docker，但无法将其安装到run。

代码语言：javascript
复制
  882  sudo apt update
  883  sudo apt install apt-transport-https ca-certificates curl software-properties-common
  884  curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
  885  sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"
  886  sudo apt update
  887  apt-cache policy docker-ce
  888  sudo apt install docker-ce
  889  sudo systemctl status docker
  890  sudo /etc/init.d/docker start

到目前一切尚好。现在，为了检查您是否可以从Docker Hub访问和下载图像，我运行：

代码语言：javascript
复制
sudo docker run hello-world

我得到了以下错误：

代码语言：javascript

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.

运行sudo dockerd返回：

我在这里完全迷失了方向，并且缺乏修复问题的背景知识--我正在上一门web dev课程，这是很多东西/练习的必修课。谢谢!

不能在Windows Subsystem for Linux下运行Docker。Docker依赖于许多WSL没有实现的Linux内核特性。你的名字在评论中看起来是这样的：

代码语言：javascript
复制
Linux DESKTOP-CD69S60 4.4.0-17763-Microsoft #864-Microsoft Thu Nov 07 15:22:00 PST 2019 x86_64 x86_64 x86_64 GNU/Linux

17763-Microsoft是关键部分--这意味着您实际上并没有运行Linux内核，而是在运行WSL内核(它近似于Windows NT上的Linux )。

您需要使用WSL2 (它运行的是真正的虚拟机，而不是部分兼容Linux的内核)或其他虚拟化技术，如VMware、Hyper-V或VirtualBox。如果你安装了Hyper-V，由于Hyper-V的工作方式，VMware和VirtualBox都不是可选的，所以如果你发现Hyper-V不能满足你的需求，你需要像Hyper-V Switcher这样的东西来关闭它(然后其他虚拟化技术就可以工作了)。

您必须将用户添加到docker组。

示例：

代码语言：javascript
复制
usermod -g  docker username

然后，您将能够连接。
