Host not available

Hi everyone
I have a problem since I installed openvas 20.08

I Can’t scan a host even when it is in the same network.
Scan reports are empty with a “Host not available” message.
I’ve been scanning it since ip 127.0.0.1 but it’s the same.

This is not a problem with “iptables”, there are no rules and the ping works between hosts.

Do you have an idea where the problem might come from ?
Thank you in advance.

You are running on a real host, no container, docker or what so ever and the OpenVAS-Scanner is running as root with all privileges and capabilities?

AppArmor or SELinux are both disabled ?

Hi,

Thank for your help.
The problem is solved.
The problem was due to a version of python not compatible with the version of openvas that I had installed.

Phyton 3.7 was required while the installed version was python 3.8.

OpenVAS is not written in Python and has nothing to do with Python you mean the GVM OSPd or something else ?
