package grub-pc 2.02~beta2-36ubuntu3.7 failed to install/upgrade: subprocess installed post-installation script returned error exit status 10

[Smit Rajput]

When I start my screen, a blue screen appears with 2 options,
1. GNU/grub-pc
2. Advanced options for ubuntu.

And I have to always click on 1 to get my PC started(or it automatically chooses 1).

Status changed to 'Confirmed' because the bug affects multiple users.

Please run sudo nano /var/lib/dpkg/info/grub-pc.postinst, and on the second line that reads "set -e", change it to "set -ex", then save and exit the editor. Then run sudo apt-get install -f, and post the output.

It looks like ucf is failing instead of prompting to update the config file. I'm not sure why that would fail.

[Steve Langasek (vorlon)]

An error code of '10' from debconf generically means that wrong arguments have been passed.

Please show the output of 'debconf-show ucf'

ok, the output of 'debconf-show ucf' looks reasonable, so the problem doesn't appear to be with debconf database corruption.

Status changed to 'Confirmed' because the bug affects multiple users.
