Install Service pack 7011 on build 7010 - failed help

My environment is Ubuntu 7.10

I am attempting to to upgrade from 7010 to 7011.

From these upgrade instructions:
(http://manageengine.adventnet.com/products/service-desk/service-packs.html#sp)

Instructions to apply the Service Pack / Hotfix

1. Shut down ServiceDesk Plus Server.
2. Run the script UpdateManager.bat (UpdateManager.sh for Linux) in the <ServiceDesk_Plus_Home>/bin folder. This opens the Update Manager tool.
3. Click "Browse" to select the Service Pack file (AdventNet_ManageEngine_ServiceDesk_Plus_<Version No>_0_0_SP-x_0.ppm file that you had downloaded) and then click "Install...".
4. Follow the on-screen instructions to apply the Service Pack / Hotfix.
5. Once the upgrade is complete, start ServiceDesk Plus Server.

Here is the error i get:
root@vm-servicedesk:~/AdventNet/ME/ServiceDesk/bin# sh shutdown.sh -S
Shutdown message has been posted to the server.
Server shutdown may take a while - check logfiles for completion
root@vm-servicedesk:~/AdventNet/ME/ServiceDesk/bin# sh UpdateManager.sh
.: 4: setcommonenv.sh: not found

thanks
