ispconfig_update.php problem

I am trying to rewrite the configuration of ispconfig again with ispconfig_update.php, but at the time of doing it throws me at the prompt and does not ask me if I want to rewrite the configuration

 

"Download and extract the latest version, chdir into install and run php -q update.php"

Code:

cd /tmp
wget http://www.ispconfig.org/downloads/ISPConfig-3-stable.tar.gz
tar xvfz ISPConfig-3-stable.tar.gz
cd ispconfig3_install/install
php -q update.php

(Instead of latest, use the version you have currently installed. I just use that snipped so that I do not have to adjust it all the time. Imho it would make sense to implement a "reconfigure services" function into ispc. That problem arises a lot of times)
