Title:
  cryptroot-unlock fails to find the askpass process

Status in cryptsetup package in Ubuntu:
  New

Bug description:
  This bug deserves some attention because it's caused by an Ubuntu
  specific patch not being in sync with upstream.

  The debian/initramfs/cryptroot-unlock script can be used with
  dropbear-initramfs to remotely unlock an encrypted root partition via
  SSH. This functionality has been broken since version
  2:2.0.4-2ubuntu1. The reason is that upstream (Debian) in version
  2:2.0.3-7 started normalizing  paths to allow the script to work on
  UsrMerged installs:

  https://salsa.debian.org/cryptsetup-
  team/cryptsetup/commit/f1c56c19fea6dc988c1f29fb

  however the Ubuntu patch introduced to fix LP: 1651818 was brought on
  to newer versions without introducing the required normalization. The
  fix is adding a "readlink" where required (patch attached).
