Im using the 2020.1 image from https://www.offensive-security.com/k...mage-download/

sudo apt-get install openvas

returns E: Unable to locate package openvas

Googling returned checking the sources.list and I currently have "deb http://http.kali.org/kali kali-rolling main non-free contrib" listed there.

I'm not too sure what to do at all and I haven't come across anything that can help.
