在 Rootless 中运行 Podman 在熔丝覆盖文件上失败
我在CentOS 7上安装了Podman。我可以在root权限下运行它，但在无root环境中失败。
这是命令和结果：
$ podman run -it busybox sh
ERRO[0000] error unmounting /home/chsun/.local/share/containers/storage/overlay/ea62672ff47fb673afd59da0bbcc2d4327327949c96193a87ea5042d87af0183/merged: invalid argument

I installed Podman on CentOS 7. I can run it under root permission, but failed in a rootless environment.
Here is the command and result:
$ podman run -it busybox sh

错误包含
无法执行fusermount3您检查过您的计算机上是否有该可执行文件吗？
如果没有，请检查它位于哪个包中。
检查是否可以直接从命令行运行。
如果没有，请使用 ldd fusionmount3 检查所有依赖项是否可用
如果缺少依赖项，请尝试找出它们可能附带的包。
https://www.man7.org/linux/man- pages/man1/fusermount3.1.html 表明
libfuse发挥作用。另请参见 https://centos.pkgs.org/7/centos-x86_64/fuse-libs-2.9.2-11.el7.x86_64.rpm.html您可能想使用以下命令安装它
： 如果二进制文件在您的系统上似乎没问题，问题可能更多地出在调用它的命令行上。不幸的是你没有发布那个。剩下需要检查的是
/etc/subuid和/etc/subgid中的参数？）The error contains
failed to exec fusermount3Have you checked whether you have that executable on your machine?
If not, check which package it is in.
Check if it can be run from command line directly.
If not, check whether all dependencies are available using
ldd fusermount3If dependencies are missing, try to figure out the package they might come with.
https://www.man7.org/linux/man-pages/man1/fusermount3.1.html indicates that
libfuseplays a role. See also https://centos.pkgs.org/7/centos-x86_64/fuse-libs-2.9.2-11.el7.x86_64.rpm.htmlYou might want to install it using
If the binary seems ok on your system the problem may be more on the command line that it is invoked with. Unfortunately you did not post that. What remains to be checked then is
/etc/subuidand/etc/subgid?)
