[SOLVED] Server 2019 unable to install CUs (0x800f0986)

[Georg]

Hello,

my server isn't able to install the monthly cumulative updates. They fail with error code 0x800f0986. Other updates get installed without problems.
So far tried
manuall install, cleaning the Update Cache, the DISM-commands also with a healthy source

Now i ran out of ideas, not having found helpful informations in the logs, i'm asking for help.

Thank you very much
Georg

Hi and welcome to Sysnative,

Upload your COMPONENTS hive.

• Navigate to C:\Windows\System32\Config and locate the COMPONENTS file.
• Please copy this file to your desktop.
• Note: If you receive an error that this file is in-use, simply reboot your computer and try again.
• Right-click on this file on your desktop and select Send To > Compressed (zipped) folder. This will create a file named COMPONENTS.ZIP on your desktop.
• If the file is too large to upload here, upload the file to www.wetransfer.com and post the link in your next reply.

Hi,

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.

Afterwards attempt to update. If it fails attach a new copy of the CBS logs.

Hi, there's a (i hope positive) difference already. Update running a lot longer, but now stops with error 0x8007371b

You did it!
The Update successfully finished.

It took so long, i lost hope several times. But there was little progress visible in the cbs.log and 20 hours later it finished.
Needles to say, i'm asking my boss for a donation since this really helped a lot and the alternative(new server) would have cost a fortune with all the work.

Can I mark this post as solved or is some kind of afterwork required?

Happy greetings
Georg

You're welcome. Glad to hear the issue has been resolved and thanks for considering a donation to Sysnative, that's much appreciated...

I will mark this thread as solved.
