Title:
  Debconf readline frontend does not show options

Status in debconf package in Ubuntu:
  Confirmed

Bug description:
  AFFECTED RELEASE:

  Bionic

  PACKAGE VERSION:

  debconf - 1.5.66

  DESCRIPTION:

  When upgrading the kernel on a recent Bionic minimal image, the user
  is prompted to resolve a conflict in the file /boot/grub/menu.lst.

  The minimal images do not have dialog/whiptail installed, so debconf
  falls back to using the readline frontend.

  The user sees the prompt: "What would you like to do about menu.lst?"
  but is not presented with the list of options to choose from.

  If a valid option is typed in, debconf will continue processing
  correctly and the list of options  appears on the screen. See also

  STEPS TO REPRODUCE:

  Launch the minimal Bionic image with serial 20190212 http://cloud-
  images.ubuntu.com/minimal/releases/bionic/release-20190212/ubuntu-18.04
  -minimal-cloudimg-amd64.img

  for example via multipass and run `apt-get update` and `apt-get dist-
  upgrade`.
