Flyingduck issues - on prem open-source version

I tried to deploy Hopsworks 3.3 on Ubuntu 22.04 but it seems to fail on the flyingduck default part. The log just contains this:

[sudo] password for ubuntu: [sudo] password for ubuntu: [sudo] password for ubuntu: [sudo] password for ubuntu: [sudo] password for ubuntu: [sudo] password for ubuntu:

So somehow the password provided is not really going into that part of the installation. Or maybe there is no debug-output coming out of the installation scrips.
