OK - the PHP8 system again -
Sorry!

Code:

PHP 8.0.3 (cli) (built: Mar  5 2021 08:38:30) ( NTS )
Copyright (c) The PHP Group
Zend Engine v4.0.3, Copyright (c) Zend Technologies
    with Zend OPcache v8.0.3, Copyright (c), by Zend Technologies

How to make PHP7 the default PHP-cli?
How to restart the ISPConfig-Update to fix the update process?

 

Thank you, seems it worked.
Also thanks for cleaning up my post
