$sudo docker info

输出

docker命令都不起作用。它们都会抛出相同的错误。

$sudo systemctl status docker

输出。

当我运行以下命令时…

$sudo服务docker重启

输出
docker.service的作业失败，因为控制进程已退出，并显示错误代码。有关详细信息，请参见“systemctl status docker.service”和“journalctl-xe”。

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

感谢@DavidMaze和@Exa对该问题的改进。
我在谷歌上搜索了这个特定错误

错误：“--disable legacy registry”标志已被删除。不再支持与旧版（v1）注册表交互

。然后我从文件中删除并保存了它。之后，它工作正常，但nvidia docker出现了新的错误。因此，我的上司建议我重新安装docker和nvidia docker。
我随后重新安装了东西。一切都安装好了，没有任何错误。但是当我试图启动nvidia docker时，它开始抛出这个特殊错误：

启动nvidia-docker.service失败：未找到单位nvidia-docker.service。

以下是详细信息

sudo systemctl状态nvidia docker

这里给出了没有这样的文件或目录的原因。

sudo服务nvidia docker启动

启动nvidia-docker.service失败：未找到单元nvidia-docker.service。

我这样做是为了解决问题。但是当我在

/lib/systemd/system

dgxuser@cse-贝内特大学：/lib/systemd/system$ls|grep nvidia

nvidia persistenced.service

这意味着没有名为nvidia docker.service的文件。现在我不明白，即使正确安装了它，为什么我不能启动nvidia docker？
看看/var/log以了解docker的日志如何？请从
journalctl
输出中发布有用的摘录。链接文件中包含X服务器日志，没有关于Docker问题的建议。感谢您回复我的问题。这就是我应该上传@DavidMaze的内容吗？是的，那个文件有一个非常强烈的提示，说明什么是错的。你尝试过什么来解决这个问题？@DavidMaze我尝试过在类似问题上给出的方法，但没有那么大的帮助。请你告诉我一些我应该试试的东西。
