[Bug 2083626] Re: package grub-pc 2.12-1ubuntu7 failed to install/upgrade: installed grub-pc package post-installation script subprocess returned error exit status 1

[Mate Kukri]

This could also be caused by cloud_style_installation=true on a system
where it shouldnt be and grub-probe returning nonsense.

OP can you post the output of debconf-show grub-pc?
