Meanwhile I could reproduce my issue with a plain file system image within a squashfs, without partition table. Here a simple list of instructions to reproduce the issue:
> mkdir /tmp/foo > truncate -s 20Gib /tmp/foo/test.img > mkfs.ext4 /tmp/foo/test.img > mksquashfs /tmp/foo/ /tmp/example.squashfs > mkdir -p /tmp/mnt/sqfs > mkdir /tmp/mnt/img > sudo mount /tmp/example.squashfs /tmp/mnt/sqfs/ > sudo mount /tmp/mnt/sqfs/test.img /tmp/mnt/img/ → Observe the error message from mount, indicating the loopback device couldn't be set up. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2120963 Title: losetup fails on image file within squashfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2120963/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
