@Andrew. I used this bugzilla, due to the commend from Steve...

If you are asking for an update to cryptsetup 2.0.4 in Ubuntu 18.10, please
file this as a separate bug report.
!!!!!
Let's please reserve this one for the
question of what changes are needed in Ubuntu 18.04 for z protected keys.

Title:
  Upgrade cryptsetup >= 2.0.3

Status in Ubuntu on IBM z Systems:
  Fix Released
Status in cryptsetup package in Ubuntu:
  Fix Released

Bug description:
  Cryptsetup is utility used to conveniently setup disk encryption based
  on DMCrypt kernel module.

  These include plain dm-crypt volumes, LUKS volumes, loop-AES
  and TrueCrypt (including VeraCrypt extension) format.

  Project also includes veritysetup utility used to conveniently setup
  DMVerity block integrity checking kernel module
  and, since version 2.0,  integritysetup to setup
  DMIntegrity block integrity kernel module.

  Version 2.0.3 include all z code for dm-crypt with protected keys

  Without cryptsetup 2.0.3 (the 3 is important) we won't be able to use
  secure key encryption with LUKS2 and the paes cipher. Only plain mode
  will be usable with cryptsetup version 2.0.1.
