redhat7.9的镜像文件失败，提示看不懂，请大家帮看看

VisionSim

挂载一个redhat7.9的镜像文件，挂在命令为mount -o loop /home/tools/iso/rhel-server-7.9-x86_64-dvd.iso /mnt/ISO/
提示mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

然后我查看了 dmesg | tail ，提示完全看不懂

换一个镜像文件能够挂载成功，请问各位是什么情况?

看看是不是这个镜像文件下载有问题，最可靠的检查代码是检查md5sum，简单点是在Windows下能查看里面的内容么？

make sure iso file is not corrupted and try again with option '-t iso9660'
