SCCM Failed To Install Updates 0x800f0831 Unknown Error (-2146498511)

Today I went to check the status of the software updates that were pushed via SCCM for this months patching and I noted a few servers failed to patch and showed the error Failed To Install Updates 0x800f0831 Unknown Error (-2146498511)

0x800f0831-unknown-error2146498511

The error Failed To Install Updates 0x800f0831 Unknown Error (-2146498511) appears because a required patch is not installed on the system.  To resolve this error we need to identify and install the required patch.

Log on to the server that failed to install the software update and open up software centre and click on updates.  You should see which patches failed to install.

To find out what update is required check the cbs.log and windowsupdates.log

The location of these log files are

  • C:\Windows\windowsupdates.log
  • C:\Windows\Logs\CBS\cbs.log

Search through these logs for missing for package in the example below we can see the patch KB4103725 is missing.

Updates_0x800f0831

Now to resolve this issue we need to head over to Microsoft Windows Update Catalog and download the required update and install on your system, restart your system then try to reinstall the original update.

The original update should now install.
