Joomla install fails-directory not empty

Error message: The problem was directory /home/user/ is not
empty! Please re-install, specifying an empty (or new) directory.

Please correct this and go to our web panel and re-submit your
joomla installation request.

The directory is empty now, but I still can’t install. Do I need to delete the databases? or is there another course of action?
Of course, as soon as I post a thread, Joomla is magically installed!

No complaints here!
