[Bug 1747619] Re: package samba-common 2:4.3.11+dfsg-0ubuntu0.16.04.12 failed to install/upgrade: subprocess installed post-installation script returned error exit status 10

[Andreas Hasenack]

Thanks.

Time to add some debugging options. As root, edit the file
/var/lib/dpkg/info/grub-pc.postinst and add this just below the existing
"set -e" line:

set -x

The top of the file should look like this:
#!/bin/bash
set -e
set -x

merge_debconf_into_conf()
(...remaining bits of the file ...)

Then save it, and run:

sudo dpkg-reconfigure grub-pc

It might make some prompts. I suggest to accept defaults, but please
take a close look at what it is suggesting.

At some point in this run, I expect it to exit with the same status code
of "10" that this bug is about. I hope that by then your screen will
have a lot of debugging information and that you can attach it to this
bug so we can figure out what is going on.
