PPC64LE Ubuntu Live image creation: Issue installing nfs-common

[Adi Gangidi]

We’re in the midst of building an Ubuntu 15.04 based live image for our OpenPOWER servers, which loads via petitboot, from across a network. We’ve run into an issue, described below, with loading an nfs-common package.

I specifically am working to create Ubuntu live image for PPC64LE.

I ran into issues initially creating a live image in a machine that’s already booted up with Live image. But now I am running into the same issue even with a machine booted up with regular ubuntu image.

Details:

Ubuntu Release used: Vivid

Issue: As I follow the attached Live image creation process from line 2, after I chroot into subdirectory with linux base system. I install a package called nfs-common (Refer Line 29 of ‘attached' Live image creation process. Also appended at the end of this email)

apt-get install nfs-common

After trying to install the above package, I am running into an issue where “dpkg” gets corrupted when I am installing this package "nfs-tools" .

After this step, trying to remove and re-install nfs-common or installing any other package does not work and throws out same errors repeatedly.

Below is a snippet

I am also appending the Live image process steps till this issue occurs (till line 29) below.

 2 apt-get install debootstrap schroot
3 mkdir work
4 mkdir chroot
5 cd work
6 debootstrap --arch=ppc64el vivid chroot http://ports.ubuntu.com/

The error ultimately looks to be this line:

invoke-rc.d: unknown initscript, /etc/init.d/gssd not found.

[Steve Langasek (vorlon)]

The failure here does point to a bug in the nfs-common packages; the init system transitions have led to several reorganizations of the startup scripts for nfs-common, and there are bugs which mean that in some configurations the package may fail to install.

However, you're installing in a chroot as part of a liveCD mastering process. No services should be started anyway, and the fact that they are means that you don't have a properly configured chroot.

The minimum fix for your environment is to install the following script as /usr/sbin/policy-rc.d
 within your chroot before installing any packages, then removing it when the setup is complete:

#!/bin/sh

exit 101

I had the same error when trying to create a livecd myself.
Post-installation script tries to determine if /etc/init.d/idmapd and /etc/init.d/gssd are executable, but those files don't exist so the script crashes.

I just created two empty files and then I installed the package with no errors.

cd /etc/init.d
touch idmapd
touch gssd

It's not the most ellegant solution but it works.
