and it works for me *if* - as you did - I format the device. But if I *don't* format it then I still get the same result, even with newer packages: testaroli# dpkg -l | grep cryptsetup ii cryptsetup-bin 2:2.6.1-3 amd64 disk encryption support - command line tools ii libcryptsetup12:amd64 2:2.6.1-3 amd64 disk encryption support - shared library testaroli# testaroli# dd if=/dev/zero bs=1M count=64 of=/tmp/disk.img 64+0 records in 64+0 records out 67108864 bytes (67 MB, 64 MiB) copied, 0.0806509 s, 832 MB/s testaroli# cryptsetup isLuks /dev/loop0; echo "\`cryptsetup isLuks\` exited with status $?" `cryptsetup isLuks` exited with status 1 testaroli# cryptsetup isLuks -v /dev/loop0 Command failed with code -1 (wrong or missing parameters). testaroli# It should say "not Luks" or perhaps "invalid device", but "wrong or missing parameters" is wrong.
