Issue: My Linux Radar Scan Node is not running, scanning or updating. I get the following error: Engine update: Scan Node Agent does not contain the latest available (revision: 65388) vulnerability signatures and updates. Either the Scan Node Agent is not running or there is no network connectivity between the Scan Node and F-Secure Radar Update Service Resolution: Kindly take note of the operating system time, as it can impact the Radar Scan Node engine updates if the time is incorrect. You can enforce manual update of Radar scan engines by executing the following command: cd /opt/f-secure/radar-scannodeagent sudo dotnet ScanNodeAgent.dll update-engines If the step above did not resolve the issue, you can perform a reset operation that will cause the engines to be downloaded from scratch: cd /opt/f-secure/radar-scannodeagent sudo dotnet ScanNodeAgent.dll reset-engines Note: Radar Scan Engine update is not instant. By default, the update check is performed once per every 4 hours so it is recommended to monitor and check after 4 hours.    Article no: 000019604

Issue: When you install a scan node and apply the license file ( sudo dotnet ScanNodeAgent.dll apply-license ), the "Central directory corrupt" error is output. Also, applying the license fails. Resolution: The installation was done as root ( su - root ) ¨which causes problems for the Microsoft dotnet package installation. To fix the issue, do the following: Uninstall the scan node: sudo apt remove --purge fsecure-radar-scan-node-agent Uninstall the dotnet package:  dpkg -r packages-microsoft-prod Reinstall the product. Restart the system. Try the installation again but this time do the installation by using  sudo instead of root ( su - root ). The installation should now finish without errors.
