package kexec-tools 1:2.0.1-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script killed by signal (Interrupt)

pstree shows that it hangs here
 ├─bash───apt-get───dpkg───frontend───kexec-tools.pos───update-grub

Attaching to update-grub:
$ sudo strace -p 8542
Process 8542 attached - interrupt to quit
read(0,

Well, it seams to wait for something from stdin, nothing comes.
Accoding to /proc/8542/fd/0 that descriptor is a (broken) pipe.

I have then changed line 1 /usr/sbin/update-grub to
#!/bin/bash -x
Attachement then log.txt from
 sudo apt-get upgrade | tee log.txt
I'm quite sure, that it would like to ask me, if I would:
install the package maintainer's version, keep the local version currently installed, show the.....

I'm quite sure, that the effected machines have still "grub" installed,
not the newer "grub2".
Here it is so, can the other affected confirm that?

In debian/kexec-tools.postinst we have
# no triggers in grub2,
# see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=481542
if [ -x /usr/sbin/update-grub ]; then
    update-grub
fi

This does not work with grub, only with grub2, suggesting using trigger here.
Temporarily removing /usr/sbin/update-grub let this package install.

Please review and apply attached patched.

Currently untested, but small trivial, should work if I have no typos.

Best regards,

Yes, I would to confirm - upgrade to grub2 repair this problem.
I'm not test patch You prepare, from my point of view problem is resolved,
we can close them.

It is possible that better solution is to patch post-upgrade script, like
You attache in another e-mail, but now I cannot verify this.

I'm sorry but "upgrading" to grub2 is not an option in every case. Support for legacy GRUB is needed too.

Also sorry, if the upgrading to grub2 would be an option, then this package has to be marked as conflicts with grub1

This bit me as well, reported as bug 523176 (now marked as a duplicate)

This bug was fixed in the package kexec-tools - 1:2.0.1-1ubuntu2

---------------
kexec-tools (1:2.0.1-1ubuntu2) lucid; urgency=low

  * Don't call db_stop in the postinst; this is not what it's for, and it
    causes update-grub to break on Ubuntu by killing the frontend that child
    processes expect to talk to. LP: #518853.

This same set of symptoms is exhibited with legacy grub installed and upgrading to precise from oneiric. Installing grub2 as workaround, will report results.

Installation of grub2 fixes problem.
