This scan result always means you are using an outdated version of our software which will likely contain issues already fixed in newer versions and the community feed may not be compatible anymore with this version. Greenbone is not in charge for your version of our software. Therefore you should contact the provider of your packages (most likely your distribution) and create a request for updated packages. How this request should be made really depends on the provider of the packages. If you don’t know how to do that you are always welcome to use our Greenbone Community Edition Virtual Machine.
