Install ZorinOS as LTSP server

Hi everybody, I'm new ZorinOS user, very user friendly distro.
I'm trying to use it as LTSP server to manage some thin clients, but following procedures shown
https://help.ubuntu.com/community/Ubunt ... ickInstall
apparently someting missing on the system during Thin Client environment creation on the server.

/usr/share/ltsp/plugings/ltsp-build-client/common/010-etc-hosts: row 3: /opt/ltsp/i386/etc/hosts: file or directory missing. Installation stopped....

Someone can help???

I've look at your post but the problem is that the system not allow to download the thin client environment to configure then as per your last link... for what I've understoud,
step 1)
sudo apt-get install ltsp-server-standalone
install ltsp server packages;

step 2)
sudo ltsp-build-client
download and create your Thin Client environment packages

step 3)
cofigure Thin Client environment according your preferences using your last guide.
actualy, for what I've seen the problem in on step 2). No way to create thin Environment!!!

I don't think so! Italc is software that allow remote control of TC and provide a set of tool to help Teaching And Learning, TC environment is praticaly a smoller version of SO that The server send to TC over Ethernet that allow Thin Client works. My suspect is that ZorinOS miss a part of SO or repositories that allow to generate this code...
