[Bug 1265428] Re: package grub-pc 1.99-21ubuntu3.14 failed to install/upgrade: subprocess installed post-installation script returned error exit status 127

[Phillip Susi]

The problem is simply that you had edited your /etc/default/grub file
and inserted some invalid text on this line:

GRUBboo# If you change this file, run 'update-grub' afterwards to update
 
Purging and reinstalling restored this file.


** Changed in: grub2 (Ubuntu)
       Status: Confirmed => Invalid
