Server 2019 Cumulative Updates failing


New Member
I received this error this month:

2022-12 Cumulative Update for Windows Server 2019 (1809) for x64-based Systems (KB5021237) - Error 0x800f0988

Any ideas on how to resolve this? It happened last month as well got a different error.
I believe 0x800f references CBS or component based servicing. 0998 is the actual error portion of the code which does not appear to be documented. You can probably get more details about what is not working by looking at the CBS log

For starters you can run the following to see if any problems exist that can be repaired.
DISM /Online /Cleanup-Image /RestoreHealth

Lots of other things to check.
