I downloaded an iso image of Ubuntu server, ubuntu-20.04.3-live-server-amd64.iso. Then I tried to mount this iso as a folder, using the usual command

mount ubuntu-20.04.3-live-server-amd64.iso ./iso

, but I received error:

mount: ./iso: failed to setup loop device for .../ubuntu-20.04.3-live-server-amd64.iso.

The same error shows up if I add -o loop or -t iso9660. I checked the thread here but the answer (lsmod | grep loop, modprobe loop) does not work for me. How to solve this problem? I'm working on Ubuntu 20.10.

PS, must I have super user privilege to mount an iso file? I saw many questions mount iso with sudo but experiencing the same error. How to check if I have permissions to use /dev/loop0?

  • Take a look at https://unix.stackexchange.com/a/462694/117549 and see if using mount ubuntu-20.04.3-live-server-amd64.iso "$PWD/iso" works. – Jeff Schaller Nov 10 '21 at 13:46
