initscript ltsp-cluster-lbserver, action "start" failed

I can log in root-server, but there is no change to use Unity (or anything else), because root-server is only for command line users.

So problem seems to me that application-server is wrong one. Should be 10.0.0.55, now it is 10.0.0.50, because of ltsp-cluster-
lbserver not running.

I did try this:

root@lubuntu-root:~# /usr/bin/python /usr/sbin/ltsp-cluster-lbserver /etc/ltsp/lbsconfig.xml
Traceback (most recent call last):
  File "/usr/sbin/ltsp-cluster-lbserver", line 5, in <module>
    from lbserver import main
ImportError: No module named lbserver

 I forced earlier 'ltsp-cluster-lbserver' package to use:

https://launchpad.net/ubuntu/precise/i386/ltsp-cluster-lbserver/2.0.0-0ubuntu2

Now ltsp-cluster works as expected.

Status changed to 'Confirmed' because the bug affects multiple users.

Could this problem be related to PYTHONPATH?

Just added the following line on /usr/sbin/ltsp-cluster-lbserver and the problem is gone.
