'ltsp-client-builder' failed with error code 1 during LTSP server installation with 20120213.1 alternate images

The description shows the log from the second attempt. The first attempt says:

This worked for me with amd64. (Installing on a blank disk, but I don't think side-by-side makes any difference here.)

Tried twice afterwords on amd64+mac image

First attempt: Entire disk with network connected ---> The installation succeeded

Second attempt: Side-by-side with no network connected ---> The installation failed. ( the installation fails even after connecting the network afterwards)

Hello Parameswaran, or anyone else affected,

Accepted ltsp into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/ltsp/5.3.7-0ubuntu2.5 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Regression tested in a VM, looks good.

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

This bug was fixed in the package ltsp - 5.3.7-0ubuntu2.5

---------------
ltsp (5.3.7-0ubuntu2.5) precise-proposed; urgency=low

  * Add an hack to ltsp-client-builder to ensure /run/resolvconf exists in
    the target. This is an hack because /run/resolvconf should always exist
    in there but for some reason, doesn't in some weird corner case.
    This hack avoids some installation failing when trying to touch
    /etc/resolv.conf (LP: #1124029)

Since 14.04 there are no alternate CD images, so I'm marking the ltsp (Ubuntu) part of this bug report as Invalid.
