Question

在运行任何docker命令时出现上述错误。当我运行以下命令

$ sudo docker info
输出

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

所有docker命令均不起作用。它们都引发相同的错误。

$ sudo systemctl status docker
输出。

当我运行以下命令时...
$ sudo service docker restart
输出

Job for docker.service failed because the control process exited with error code. See _"systemctl status docker.service"_ and _"journalctl -xe"_ for details.

我已经运行了“ systemctl status docker.service” ，并且还运行了“ journalctl -xe” 命令以了解问题所在。 journalctl输出包含

Answer 1

感谢@DavidMaze和@Exa完善了此问题。
我用这个特殊的错误ERROR: The '--disable-legacy-registry' flag has been removed. Interacting with legacy (v1) registries is no longer supported进行了搜索。然后我将其从文件中删除并保存。在那之后，它工作正常，但是nvidia-docker中出现了一个新错误。因此，我的主管建议我重新安装docker和nvidia-docker。
我按照LINK进行了重新安装。一切都已安装，没有任何错误。但是，当我尝试启动nvidia-docker时，它开始抛出此异常错误：Failed to start nvidia-docker.service: Unit nvidia-docker.service not found.

以下是详细信息。

此处给出了没有此类文件或目录的原因。

sudo service nvidia-docker start
Failed to start nvidia-docker.service: Unit nvidia-docker.service not found.
我这样做是为了解决这个问题。但是当我在/lib/systemd/system

中运行以下代码时，它得到确认

dgxuser@cse-bennettuniv:/lib/systemd/system$ ls | grep nvidia
nvidia-persistenced.service
这意味着没有名为 nvidia-docker.service 的文件。现在即使正确安装我也不明白，为什么我不能启动nvidia-docker？

docker：无法通过unix：///var/run/docker.sock连接到Docker守护程序。泊坞窗守护程序正在运行吗？适用于Ubuntu 16.04
