Bug#1031221: grub-installer: db_input / db_go undefined in postinst

[Emanuele Rocca <ema@debian.org>]

Package: grub-installer
Version: 1.186
Severity: normal
Tags: newcomer

Hi,

The function die() in /var/lib/dpkg/info/grub-installer.postinst calls db_input
and db_go, but the functions are not defined:
https://salsa.debian.org/installer-team/grub-installer/-/blob/master/debian/postinst#L16

Here's the relevant error in /var/log/syslog:

  /var/lib/dpkg/info/grub-installer postinst: line 16: db_input not found configuring 'grub-installer' failed with error code 1

The script should source /usr/share/debconf/confmodule.

Thanks,
  ema
