Issu on installation

I try to install on Linux Ubuntu 11.04.
I have this message on intall screen :

incorrect value for 'Parameter file name', does not include a valid directory name

I change it to /home/projects/files/config/parameters.php

Do you have a idea ?
Thanks

Thanks, any change after i create this directory.

A other way ?
