It would be nice to identify the error source to tell others how to solve the issue. If you turn error reporting on, you should get a feedback about what went wrong. You're not the first reporting issues getting WackoWiki deployed on Ubuntu. Did you tried to turn mode_rewrite OFF? And what is the error log saying?

We do test WackoWiki ((/Org/Tools/Hosting/TestServer locally with XAMPP)) and on our server (shared hosting).
You can try to run it in a different local/remote environment till the error source is found if that is feasible.
