A script to install GVM / OpenVAS 11 on Ubuntu 20.04
Usage (note the text editor line -- use whichever editor you'd like but take a look through the script to see what it's going to do when you run it.):
wget https://raw.githubusercontent.com/<account>/gvm_install/master/install_gvm.sh
nano install_gvm.sh
chmod +x install_gvm.sh
sudo ./install_gvm.sh
Based on koromicha's excellent guide. Thanks to the commenters there as well for useful troubleshooting info.
Takes a while to do everything (a couple of hours on my last test).
When creating a task be sure to select the "Created OpenVAS Scanner" from the drop-down.
