The installation is successful but the issue is that the vulnerability database is taking too long to get updated (current). It still says updates are in progress. Is there any way i can do this manually.
depending on your system this could also take several hours. It’s doing the updates in the backround. You could check that with htop. There you should find a service from gvmd who needs a decent amount of your CPU.
On my installation it took 4 hours I think.
Please note that the Atomic repository (which is mentioned / used in the installation guide) is shipping heavily outdated and already EOL versions of the GVM software stack where no feed compatibility is given / no support can be expected.
This was already reported a few years ago like shown / reported to the repository maintainer below.
