【解决方案1】：

问题解决了。

我还在 https://app.element.io/#/room/#podman:fedoraproject.org 的播客室发布了这个问题

建议我使用 podman 重置（命令跟踪如下），然后它抱怨 storage.conf，我删除了该文件并再次重置。然后它的工作。

我仍然想知道 storage.conf 内部是什么导致了这个问题，但我在调查之前删除了它。最后它的工作，我能够继续。希望能帮助到你。

注意：发布删除 storage.conf 文件和 podman 重置，我也尝试使用 docker build 来检查 docker 是否对 storage.conf 文件有任何依赖，但是没有，docker build 也成功执行（下面的命令跟踪）

root@cks-master:~# podman system reset -f
A storage.conf file exists at /etc/containers/storage.conf
You should remove this file if you did not modified the configuration.

root@cks-master:~# rm /etc/containers/storage.conf

root@cks-master:~# podman system reset -f

root@cks-master:~# podman build -t simple -f /vagrant/files/ch5Dockerfile .
