GVM Install on Kali

I wrote a install howto for Kali Linux … Did I forget something?

Fresh Install: I saw only one NVT

CiscoWorks Management Console Detection (HTTP)

when i run greenbone-nvt-sync … It hangs?

I consider that is a problem with the nvt database - What should I do?

gvmd --rebuild as root or as _gvm user?
