OCS 2.2.1 Server on Ubuntu

Hi,

I tried to install the current Version 2.2.1 under a Ubuntu VM, but the Setup doesn't work. After typing 'sh Setup.sh' my Server prompts:

: not found4:
:not found3:
:not found5:
:not found8:
: not found0:
: not fuund2: echo
+----------------------------------------------------------+
|                                                          |
|  Welcome to OCS Inventory NG Management server setup !   |
|                                                          |
+----------------------------------------------------------+
: not fund8: echo
: not found9:
Trying to tetermine whitch OS or Linux Distribution you use
: not found2:
Setup.sh: 96: Syntax error: "elif" unexpected (expecting "then")
#

I already have the 2.1.2 Version running under Ubuntu and this works fine. Any idea why I can't install the new Version?

Regards,

Frank
