[Bug 1124029] Re: 'ltsp-client-builder' failed with error code 1 during LTSP server installation with 20120213.1 alternate images

[Launchpad Bug Tracker]

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)

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

Status in “ltsp” package in Ubuntu:
  Triaged
Status in “ltsp” source package in Precise:
  Fix Released

Bug description:
  == Rationale ==
  For some reason /run/resolvconf sometimes (race condition) doesn't exist at the time we try to setup LTSP. This is a bug in its own but is then making a touch /etc/resolv.conf fail in ltsp-client-builder.

  The workaround for now is to call mkdir -p /run/resolvconf through in-
  target, thereby ensuring /run/resolvconf always exists, which should
  make the touch succeed.

  == Test case ==
  It's unfortunately a race condition, so short of trying a few installs and considering it fixed, there's no trivial way of confirming this.
  One could try to remove /run/resolvconf on purpose just before ltsp-client-builder is called and see what happens, but that'd require some pretty careful timing.

  == Regression potential ==
  This is a mkdir -p of a directory under /run, so it really shouldn't ever fail.
  However the fix is just working around a bigger problem and if anything inside the target tries to resolve a hostname, this will still fail as we won't have any DNS servers configured.

  --- original report ---

  The following error occurs during LTSP server installation on hardware
  with Ubuntu 12.04.2 LTS "Precise Pangolin" - Release amd64+mac
  (20130213.1).

  Feb 13 11:40:02 main-menu[409]: (process:21643): mount: mounting proc on /target/proc failed: Device or resource busy
  Feb 13 11:40:02 main-menu[409]: WARNING **: Configuring 'ltsp-client-builder' failed with error code 1
  Feb 13 11:40:02 main-menu[409]: WARNING **: Menu item 'ltsp-client-builder' failed.

  **This is with amd64+mac and will report the outcome of i386 and amd64
  installations shortly.

  == Test case ==
  1) Press F4
  2) Choose LTSP
  3) Install
  (This is a side-by-side installation along with another precise alternate one. Not sure if that's any reason for this)
