[Bug 2031420] Re: package memtest86+ 6.20-2 failed to install/upgrade: installed memtest86+ package post-installation script subprocess returned error exit status 127

[Brian Murray]

I'd thought there might be some special grub handling in ubuntu-release-
upgrader but I also tried an upgrade by modifying my
/etc/apt/sources.list to change lunar to mantic and then running 'apt-
get dist-upgrade' and still encountered the same crash. Additionally,
the file '/etc/grub.d/10_linux' starts with the following:

bdmurray at clean-lunar-amd64:~$ head -n10 /etc/grub.d/10_linux
#! /bin/sh
set -e

# grub-mkconfig helper script.
