This morning, I opened the OpenVAS Web UI and noticed I was unable to run any tasks. Upon checking the Feed Status, I saw an error indicating a synchronization issue with the NVT feed.
The error message reads: Synchronization issue: Could not connect to scanner to get feed info.
To troubleshoot, I started updating the feeds. While the feeds are updating, the NVTs are not being updated. See the screenshot below for reference:
During troubleshooting, I found that the /run/ospd/ospd-openvas.sock file was missing, and a feed-update.lock file was in its place.
To resolve, I removed the feed-update.lock file and re-pulled all OpenVAS containers, ensuring that I did not remove any volumes. This preserved the database records and previous scan data, and restored the ospd-openvas.sock file.
Afterward, I updated the feed, and the update completed successfully.
For safety, I recommend making a backup or taking a snapshot of the VM before performing similar actions.
