I'm on 14.04 (Trusty) and am still experiencing the same issue. I took the patch from #7 and it fixes the issue for me. Unfortunately, without you guys rolling updated libcryptsetup4 packages, I keep getting rolled back to an unfixed version on every update. Subsequent kernel releases (3.13.0-80 and later) do not seem to fix the problem for me. I'm currently experiencing the issue with 3.10.0-91-generic.

Booting linux-image-3.13.0-83-generic and running cryptsetup results in: Required kernel crypto interface not available. Ensure you have algif_skcipher kernel module loaded. The module algif_skcipher is loaded, so the tenor of the error message is wrong, but cryptsetup cannot open the container, so at least there _is_ some error. Probably it's related to some unsupported instruction set.
