The following command works: sudo losetup /dev/loop0 /home/pgmaudio/2016-11-25-raspbian-jessie-lite.img
When one does fdisk -l /dev/loop0 the result is sensable: Device Boot Start End Blocks Id System /dev/loop0p1 8192 137215 64512 c W95 FAT32 (LBA) /dev/loop0p2 137216 2715647 1289216 83 Linux If you try something like sudo mount /dev/loop0 p2 /mnt The report is that it doesn't exist and ls /dev/loop0* only shows the original loop0 loopback device. I looked through all of /dev such as /dev/mapper and there seems to be nothing else pertaining to loop0 so what am I missing? I have tried this on the debian raspbian image above plus some images I created with dd from the sd card of a working raspberry pi and both images showed up with fdisk -l but nothing else. Thanks for any constructive ideas. Martin McCormick
