I installed the latest CE ISO yesterday and according to the documentation, if I download the latest feed (which I’ve done), I should see options for upgrading the OpenVAS system if upgrades exist. I can’t find the option to upgrade my system. Am I looking in the wrong place? Is there another step that I need to take in order to be able to upgrade?
The GCE is currently at 4.2.20 which is matching your downloaded version.
If a new version of the GCE is published you need to download and install from a fresh .iso as shown in the “The Features of GSM and GCE are tailored to the environment” table:
GSM (professional environments)
GCE (SOHO environments)
System Update
Contains Security Updates, can update from any version to latest release, Grace Periods for EoL and LTS, Migration of data and configurations between appliances and versions
