LanGuard console is not showing any patches for approval under Configuration -> Patch Auto-deployment, even though the repository directory contains new patches that have not been deployed.
Such behavior is an indication that the Program Updates may not have been successful, a new Program Update is in progress right now, or the updates folder has become corrupted.
Please, purge the updates folder and manually download the definitions as described in Updating LanGuard Server Manually article.
Launch GFI LanGuard, go to Configuration > Software Updates > Patch Auto–Deployment, and verify that new patches are there to approve. If the issue persists, contact GFI LanGuard Support.
