Hi,
I downloaded and installed the GCE 5.0.12 VM and everything works fine. Then I started feed update from console and it took about one and half hour. But when I lokked at the secinfo database I saw there are missing information about secinfos. I also installed OpenVAS 9 and when I looked at the secinfo on OpenVAS I saw more secinfo entry. In GCE it was about 530.000 and in OpenVAS it was about 800.000. I searched in detail and I realized there hasn’t been any CVE after 2013 for example. I made two or three times feed update on GCE but it is still the same. Database don’t update itself.
