CodeWarrior v2.10 does not support Ubuntu, it only works for Windows XP/Vista/7. We have Eclipse CodeWarrior v10.2 which supports Ubuntu v10.04. But CodeWarrior v10.2 only supports parts of Qorivva device, including MPC560xP, MPC56xxF, MPC567xK, MPC5643L, MPC56xxS, MPC5668E/G. But it does not support MPC560xB. Sorry for this inconvenience.
