Hi,
please avoid cross-posting to different categories. We have deleted you second post at the GCE category because that category is also only about the virtual Greenbone Community Edition appliance.
Greenbone is the maintainer of the project formerly known as OpenVAS. Greenbone doesn’t provide nor develop packages for any Linux distribution besides its own Greenbone OS. All freely available packages are 3rd party packages with different quality from different sources. Therefore the information at the OpenVAS website was heavily outdated and got removed.
Also in the meanwhile we decided to change the branding of the free software project to Greenbone Vulnerability Management (GVM). Only the scanner will be still named after OpenVAS. All further information about the project and its software is and will be collected in this forum.
The script is deprecated because it wasn’t very useful for debugging real user issues.
