Bug description:
  Steps to reproduce:
  1. Install Ubuntu 19.10 MATE with Encryption and LVM
  2. Ensure that it boots after install
  3. Run `sudo apt autoremove`

  Expected results:
  * there are no packages to remove

  Actual results:
  * it tries to remove cryptsetup:

  $ sudo apt autoremove
  [sudo] password for mate:
  Reading package lists... Done
  Building dependency tree
  Reading state information... Done
  The following packages will be REMOVED:
    cryptsetup cryptsetup-bin cryptsetup-initramfs cryptsetup-run
  0 upgraded, 0 newly installed, 4 to remove and 23 not upgraded.
  After this operation, 1 178 kB disk space will be freed.
  Do you want to continue? [Y/n]

  and this will lead on un-bootable encrypted system.
  This is very unexpected and dangerous.
