运行任何 docker 命令时出现上述错误。当我运行以下命令时

$ 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 命令都不起作用。他们都抛出相同的错误。

$ sudo systemctl status docker
输出。

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

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

“journalctl -xe”命令抛出的outpot的更完整的txt文件

感谢@DavidMaze 和@Exa 完善了这个问题。
我用谷歌搜索了这个特定的错误ERROR: The '--disable-legacy-registry' flag has been removed. Interacting with legacy (v1) registries is no longer supported。然后我将它从文件中删除并保存。之后，它工作正常，但在 nvidia-docker 中出现了一个新错误。所以我的上级建议我重新安装 docker 和 nvidia-docker。
我按照这个链接重新安装东西。一切都安装好了，没有任何错误。但是当我尝试启动 nvidia-docker 时，它盯着抛出了这个特定的错误：Failed to start nvidia-docker.service: Unit nvidia-docker.service not found.

以下是详细信息。

这里给出了没有这样的文件或目录的原因。

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。但是当我运行以下代码时，它得到了证实/lib/systemd/system

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。现在即使正确安装后我也不明白，为什么我无法启动nvidia-docker？
