Windows Server 2016 Standard - Error 0x800f081f

[HamUser123]

When trying to install 2025-02 Cumulative Update for Windows Server 2016 for x64-based Systems (KB5052006), I get Error 0x800f081f.

Did a sfc /scannow, it fails at 4%:
Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 4% complete.

Windows Resource Protection found corrupt files but was unable to fix some
of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For
example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not
supported in offline servicing scenarios.


Did a DISM /Online /Cleanup-Image /RestoreHealth
[==========================100.0%==========================]
Error: 0x800f081f

The source files could not be found.
Use the "Source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see Configure a Windows Repair Source.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log
