ARPV6/ICMPV6 socket: Address family not supported by protocol

GVM versions

gsad: Greenbone Security Assistant 21.4.1~dev1
gvmd: Greenbone Vulnerability Manager 21.4.2

Environment

Operating system: Ubuntu 20.04.2 LTS
Kernel: Linux 5.4.0-77-generic
Installation method / source: Kali Linux Repo & Manual Compile

I have been on this for a few days now, and I can’t find the issue even after trying Ubunutu and manual compile, Fedora via Atomic, Fedora and manual compile, and finally Ubunutu with kali linux repo. I keep getting the following error when trying to run scans when the Alive Test for target is set to anything but consider alive.

It be nice to get the other 8 options working.

Does anyone have any idea?

Disabling boreas resolved the issue.

echo “test_alive_hosts_only=no” >> /etc/openvas/openvas.conf

I do get exactly the same problem. Is there any other solution than disabling Boreas? Why is it failing in the first place?
