Troubleshooting SCCM 0x80246002 Error When Downloading 3rd Party Updates from SCUP. Failed to download updates to the WUAgent datastore. Error = 0x80246002. This problem may appear with 3rd party updates from SCUP.

The first log to look at is wuahandler.log, you can see this error:

Failed to download updates to the WUAgent datastore. Error = 0x80246002.

0x80246002 refers to A download manager operation that could not be completed because the file digest was not recognized.

So the next step is to look at UpdatesHandler.log:

Failed to initiate install of WSUS updates, error = 0x80246002
Failed to start batch install through WSUS Install handler , error = 0x80246002

Next look at windowsupdate.log, which may have the same errors as above.

First try re-distribute the content to DP, delete the existing deployment, and re-create the deployment.

If the issue still persists try the next steps:

1. Open the SCUP console, go to Publications, and look at the folder that has 3rd party updates (like Java). Select the folder, click on Publish on the top;

2. During the publish option, select the following Sign All, click Next, Next, and Close. Check SCUP.log for any errors;

3. Go back to the SCCM console, perform software update synchronization, and check wsyncmgr.log;

4. After the synchronization success, re-download 3rd party updates to the package;

5. Delete the existing deployments because the client must re-download the new package that you download now. Else client will follow the old content that was stored in ccmcache and it will keep failing;

6. After you delete and re-create the deployments, initiate the machine policy (using client notification for clients) to download the new policy;

7. Log in to one of the problematic clients, open the Software Center, and install the updates manually. Check logs (wuahandler.log, updatesdeployment.log, updatehanlder.log, windowsupdate.log).

NOTE: After all these steps the issue with 3rd party updates must disappear.
