[SOLVED] dpkg error, post-installation script error code 2

Hi all, long story short: A friend of mine installed BL on his HP laptop and, after his few first days as a cli user, he encountered this issue (I know, he's gotta register himself, but his English is not that fluent).

lucio@vertice:~$ sudo dpkg --configure linux-image-3.16.0-4-amd64
Configurando linux-image-3.16.0-4-amd64 (3.16.36-1+deb8u1) ...

He cannot install/upgrade any package.
This is our first query after a few searches. This guy, Lucio, has installed jgebowski's libpurple for facebook @ pidgin plugin from GIT, so that's the furthest we could track the issue (not quite technical information, but hey! it's drink_n_drive writing).
Any suggestions or extra output you need? Thanks in advance.

It sounds like he has a messed up grub file.

Maybe try reinstalling grub, assuming it is installed to the first drive (sda), with

sudo grub-install /dev/sda && sudo update-grub

If that doesn't work then please post the output of

cat /etc/default/grub

Re: [SOLVED] dpkg error, post-installation script error code 2

This will make the command speak English:

sudo LC_ALL=C dpkg --configure linux-image-3.16.0-4-amd64

Looks like it's failing on the initramfs post-install script for the kernel due to a missing /etc/default/grub

To recreate this file, try:

sudo dpkg-reconfigure grub-pc

Or perhaps:

sudo aptitude reinstall grub-pc

sudo aptitude reinstall grub-pc

That did the trick! Could you figure out what happened? How could there be a conflict with grub?

Thank you again.

Could you figure out what happened?

User error, perhaps?

I often delete files accidentally, I'd be lost without backups
