Installing ISPConfig 2 on Ubuntu 11.10

[bkilinc]

I am moving to a new server and I installed Ubuntu 11.10 it and followed the instructions at
http://www.howtoforge.com/perfect-se...04-ispconfig-2

everything went fine

I also copied databases and www folders at night.

I came to the step to install ISPConfig 2

when I executed setup, it gave 'Your Operating System is not supported!' message.

Right now, what must I do ? should I format server and start again with 11.04. Or is there a work around to install ispconfig 2 on ubuntu 11.10, I hope there is
