parallel tools (ubuntu 8.10)

Hi so I installed Ubuntu on my parallels 3 on my macbook, when I tried to install parallels tools it prompted:

"To install Parallels Tools:
1. Run Terminal.
2. Mount cdrom.
3. Change the directory to cdrom.
4. Run the sh parallels-tools.run with root privileges.
5. Follow the instructions of the Parallels Tools Installer."

So I did exactly this, after the cd was mounted, I run the terminal and run sh parallels-tools.run

I got this message:

"You are about to start installing Parallels Tools. Save your data and close all
applications to prevent data loss during possible X-Server restart.
Continue ? [Yes/No]:Yes
Found xorg version .
Installation for xorg.. not found."

Anyone can help??

 

this version of ubuntu is not supported in PD v3.
That's it.

 

I had no problem with parallel 4.
just open a shell, go in cdrom and type $ sudo ./install

that's all.
