Thanks, worked
I found another (unimportant glitch)...or maybe I am the only one who runs it with cron?
first i have overseen that the preferences.bash is only a template in the original and have to be copied without the template addition in the file name to work.
The updates runs now automatically and starts the same download-updates.bash again...
in my case not ideal, because I am running all my updates from another bash script (edited get-all-updates.bash)
At least I will see a problem in the morning, because my logcheck script was not running and I am missing my daily WSUSoffline-Update email
I don't see an easy way to solve this problem and actually it is not necessary (or a waste of time), because the next night it will run fully and I am forced to check the logs
