Hello Hans, Hello Christian. Thank you so very much for your answers. They really helped, you solved it.
Yes I am having a minimal server installation. And yes, as i looked into /etc/apt/sources.list an entry like deb http://archive.ubuntu.com/ubuntu bionic universe was missing. Just added it and see, works just fine.
