Drupal already installed Error After Successfull Installation

My distro does not seem to correctly redirect to the new site instead, is stuck on {base_url}/install.php, i have tried to install it multiple times the wizard is ok but its just not working properly, what could be causing this?, trying to run the update script, fails with this error :
