ubuntu mount loop-device bash

I'm updating my dependencies and I've been struggling with this for a few days now and could really use some help. I'm working with an scenario while trying to mount a loop file in Ubuntu 20.04. The command I am using is: ```bash sudo mount -o loop /path/to/myfile.img /mnt/mymountpoint ``` However, I receive the following behavior message: ``` mount: /mnt/mymountpoint: mount failed: loopback device not found. ``` I've verified that the image file exists and is a valid loop file using `file /path/to/myfile.img`, which returns: ``` /path/to/myfile.img: ISO 9660 CD-ROM filesystem data 'My Disk Image' (bootable) ``` I also checked the status of loop devices by running `losetup -a`, and it returns nothing, indicating that no loop devices are currently set up. I've tried creating a loop device manually with: ```bash sudo losetup /dev/loop0 /path/to/myfile.img ``` But that results in: ``` losetup: /dev/loop0: failed to set up loop device: Device or resource busy. ``` I made sure that I don't have other processes using the loop devices, and I even rebooted the system to clear any potential locks. Is there a way to troubleshoot this, or is there something I might be missing in my approach? Could it be related to some specific configuration in my Ubuntu system? This is part of a larger application I'm building. I'd really appreciate any guidance on this.
