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 -- libdevmapper incompatible with cryptsetup kernel driver https://launchpad.net/bugs/64625 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
