Hi,
I’ve solved the issue, thanks for your help.
Based on your reply, I found that /media/nx is automatically created when I plug in a USB flash drive. When I clone the system with /media/nx present, and then restore it to another NVMe drive, I encounter permission issues.
I deleted /nx before cloning, and after restoring and plugging in the USB flash drive again, the system automatically creates /nx without any permission issues.
Thanks again for your assistance.
Regards,
