In that case, it would be a bug in whatever method you used to install
Ubuntu, yes.  Please provide us details on how you installed Ubuntu, so we
can reproduce this error.

Yes, it should.  It was a bug that we were unconditionally installing
cryptsetup to the initramfs before for all users that had cryptsetup
installed, bloating the initramfs and slowing down their boot.  This bug has
now been *fixed*, and in the process it has exposed a problem with your
system.  That may, as you say, also be a bug in the Ubuntu installer; but
that is NOT grounds for restoring the previous buggy behavior.

Title:
  cryptsetup removed from initrd.img on upgrade to 13.10

Status in “cryptsetup” package in Ubuntu:
  Invalid

Bug description:
  After an apparently successful upgrade from 13.04 to 13.10 (Kubuntu), reboot was requested. My computer failed to boot. Error:
  /scripts/local-top/cryptroot: line1: /sbin/cryptsetup: not found.

  `lsinitramfs initrd.img-3.11.0-11-generic` does not list cryptsetup

  It should have been detected that my filesystem is encrypted, and
  cryptsetup and associated files should have been placed into the
  initramfs

  I have an encrypted partition, created with `cryptsetup luksFormat`,
  containing LVM for /root /home and swap.
