OpenVAS won't generate SCAP Database
It seems to be the case that an apt-get dist-upgrade
caused the trouble. After setting up another VM leaving this step out the installation finished sucessfully.
// Eventhough I got it running I'm now using Ubuntu Server and the packets provided by Mohammad Razavi when it comes to virtualized instances of OpenVAS. I had severe problems handling the scans. The scan processes started but hung themselfes after 1% - 9% and did never finish. Didn't have to deal with problems like this in presvious versions of kali.
