[SOLVED] Windows Server 2019 - Failing to install KB5055519 - 0x800F0985

[Mark_S]

Hi, been having an issue installing CU on 1 server for a few months now, getting error 0x800f0954.

Have tried SFC (no corruption found) and DISM which is failing (including using a mounted ISO of the installation media as a source). DISM seems to be failing to find certain packages (0x800f0954 - CBS_E_INVALID_WINDOWS_UPDATE_COUNT_WSUS), hence trying to specify the installation media as a source but still get an error about them, albeit slightly different (0x800f081f - CBS_E_SOURCE_MISSING)

I've attached CBS logs and ComponentScanner log.

Any help would be greatly appreciated.

Realised I cleared out the CBS logs which were missing the failed attempt to install the update. They're now attached to this reply.

Hi and welcome to Sysnative,

Please don't remove logs...

Step 1. Download

SFCFix and save it to your desktop.

Warning: This fix was written specifically for this system. Do not run this fix on another system.

• Save any work you have open, and close all programs.
• Download the attachment SFCFix.zip and save it to your desktop.
• Drag the SFCFix.zip file over the SFCFix.exe executable and release it.

• SFCFix will launch, let it complete.
• Once done, a file will appear on your desktop, called SFCFix.txt.
• Post the logfile (SFCFix.txt) as attachment in your next reply.

Step 2. Run the following DISM command and post the result. If it fails attach a new copy of the CBS log.

DISM /online /cleanup-image /RestoreHealth

Thank you, this worked perfectly. The DISM completed successfully and the Windows update successfully applied.

I have 2 other servers which seem to have similar issues, but with different corrupted payloads. Would it be best to create new thread for each individually? I couldn't see anything about the rules regarding this in the posting instructions.

Hi,

You're welcome. Gad to hear the issue has been resolved...

Please start a new thread for the other servers just to avoid any confusions.
