[Bug 1822270] [NEW] Debconf readline frontend does not show options

[Tobias Koch]

Public bug reported:

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
https://pastebin.ubuntu.com/p/8xvSn88SKG/

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`.
