Public bug reported:
I'm trying to create a LUKS partition on a USB stick thus:
sudo cryptsetup --verbose --verify-passphrase luksFormat /dev/sda2
It asks for a passphrase, then says:
Failed to setup dm-crypt key mapping.
Check kernel for support for the aes-cbc-essiv:sha256 cipher spec and verify
that /dev/sda2 contains at least 133 sectors.
Failed to write to key storage.
** Affects: cryptsetup (Ubuntu)
