ValueError: Redis URL after installation

Junaverse · March 30, 2023, 10:26pm

I just tried to install openvas on kali linux (VirtualBox).

I removed openvas completely and reinstalled it multiple times to see if this fixes it, but I always get the same result at the end of the day.

Ive done update and upgrade of linux than apt installed openvas. After that I ran sudo gvm-setup which took ages but worked completely fine.
BUT when trying to run sudo gvm-check-setup or sudo gvm-start erroring with the following message:

Check log file permissions /var/log/gvm/openvas.log
You probably ran “openvas -s” for the first time as root, so this log file is created as owned by root.
In the systemctl service context, “openvas -s” is executed as _gvm, preventing the system to get the configuration, i.e. the database address (db_address)
