Today I wanted to install new updates on existing images on SCCM. Software Library> Operating Systems>Operating System Images> Right click on the image>Schedule Updates. Sometime later, Schedule Updates Status failed with the message:
Failed to apply one or more updates
I checked the OfflineServicingMgr.log and see the error:
Failed to remove previously existing staging folder C:\ConfigMgr_OfflineImageServicing
So, It can not clean the previously mounted folder and I need to manually clean and unmount this folder to resolve the issue.
Resolution:
Open Command Prompt with the admin privileges,
Run these commands on the server
dism /get-MountedWiminfo
dism /cleanup-wim
dism /cleanup-mountpoints
Reboot the server. Make sure you reboot the server. If you don't, you will have same problem again.
And finally OfflineServicingMgr.log looks fine.
