You can install updates to Tenable Core without a connection by uploading the Tenable Core Offline Update ISO file. Uploading the ISO file applies updates not only to Tenable Core, but to any other supported Tenable applications you have installed.
To install updates offline:
Download the ISO file from the Tenable Downloads page.
Upload the file via scp.
Note: The target line may vary; however, the destination must be the following path:
/srv/tenablecore/offlineiso/tenable-offline-updates.isoExample: scp local-iso-file.iso user@host:/srv/tenablecore/offlineiso/tenable-offline-updates.iso
After the upload, updates will be applied automatically at the configured time set on the Update Management page or on the next reboot. Alternatively, you can manually install updates on the Software Updates page.
Note: Once the ISO file is uploaded, no further action is needed. However, you can make subsequent updates by replacing the existing ISO file if desired.
