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

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.

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.
