我对Docker或Linux不太满意，无论如何我都无法运行Docker映像。我只是安装了清晰的Linux OS（尝试了两次），并尝试安装docker并启动了一些容器。
我可以运行docker run hello-world并获得正确的数据，但是如果我执行docker run ubuntu，则它将加载约5分钟，然后出现错误：
[york@york docker-git]$ docker run ubuntu
Unable to find image 'ubuntu:latest' locally
latest: Pulling from library/ubuntu
docker: unauthorized: authentication required.
See 'docker run --help'.
我尝试了类似nginx或java的不同图像。
当然，我使docker login不变...
也尝试使用MTU制作一些东西，在/etc/docker/daemon.json中将mtu分别设置为900、1454和1500，但也许在这里做错了。或其他任何地方。
我的步骤
systemctl start docker systemctl enable docker docker run ubuntu OS：Manjaro KDE
