Hi Steve, In Lucid and prior versions of Ubuntu, when using the Alternate installer the user would be presented with three choices when installing to a LUKS partition: AES, Blowfish, Serpent or Twofish. Of course, additional options were also presented, but these four basic ciphers were always available.
Some time around either Maverick or Natty, the option for Twofish was removed, and now it is only possible to install onto AES, Blowfish, or Serpent, but not Twofish. Note that if one installs Lucid using Twofish partitions, then upgrades through the versions all the way up to Oneiric (as I have done on the machine in this report), the Twofish partitions will work fine. There is no problem continuing to use them in the newer versions of Ubuntu once they are installed, it is just that the newer versions of Ubuntu do not offer the option of Twofish any more in the Alternate installer. Thanks for looking into this. Let me know if there is anything I can do to help.
