Fails to publish the expiration for both the x86 and x64 Wireshark 2.0.3:
2016-06-13 18:18:49.747 UTC Error Scup2011.8 Publisher.GetLocalFileDetails VerifyAndPublishPackage(): Failed to Verify Signature for file: \\SERVER1\UpdateServicesPackages\fdd53870-09eb-4ac9-901c-e3f454ec6107\c36152b3-5913-4691-924c-cbfe3077a7ef_1.cab
Can you check if that file exist "\\SERVER1\UpdateServicesPackages\fdd53870-09eb-4ac9-901c-e3f454ec6107\c36152b3-5913-4691-924c-cbfe3077a7ef_1.cab"? We have mainly seen this when the published updates are being cleaned up and deleted (WSUS Cleanup or other task). This will cause the file hash check to fail when it attempts to expire the update since the file no longer exist.
