Comment 7 for bug 64625

The problem is resolved !

Sometime, complex explanations of experts aren't useful and can conduct to bad way.

In fact, as previous message, simple use of
sudo modprobe aes dm-crypt dm_mod
solves the problems.

Moreover, I'm a new Ubuntu user and I'm not accustomed with sudo: cryptsetup must be use too with sudo.

So with FreeOFTE i now have access to my luks partition under Linux and Windows.

But I don't understand another detail :
this command doesn't work
sudo cryptsetup --cipher aes -s 256 luksFormat /dev/loop0
but this one work fine
sudo cryptsetup --cipher aes --keysize 256 luksFormat /dev/loop0

Same problem with
sudo losetup --encryption aes --keybits 256 --nohashpass /dev/loop0 volume
and
sudo losetup --encryption aes --keybits 256 -N /dev/loop0 volume
