When trying to mount a loop device, I’m getting “mount: /mnt: mount failed: Unknown error -1”.

Can’t access loop device: “mount failed: Unknown error -1” or “failed to setup loop device: Operation not permitted” · Issue #2980 · lxc/lxd suggests that it’s impossible to manipulate loopback devices inside an LXD container – at least, without tweaking the container’s setup to specifically allow specific loopback devices.

So use the newly-available full VM ARM64 environment with arch: arm64-graviton2.
I confirm that mounting loopback devices works there.
