The resolution to this problem for me was to run gvm-setup once more. It did something with “Modifying Default Scanner” that resolved my issue.
Specifically, the order of operations that worked for me was:
- gvm-setup (initial setup)
- gvm-start
- sudo runuser -u _gvm – gvmd --create-user= --password=
- gvm-setup
As frakman1 stated, I then checked Configuration->Scanners, and then under “actions” checked “Validate” for all scanners and was good to go.
