SSDs are slow to arrive, so I retried to manually install the latest April cumulative update for Windows Server 2016 x64 (KB5036899), a 1.71 Gb msu file.
The “SoftwareDistribution” came in at over 9 Gb, it seemed to be proceeding then after a long time the automatic cancellation of the update started, so there is bound to be a problem.
I attach the CBS.log inherent this failed operation, the installation window closed automatically after the automatic cancellation.
Consider that SoftwareDistrubition I had emptied it before I started, so clean start, and in the CBS I see crazy problems, like:
DPX Extraction of file: update.ses failed because it is not present in the container (\\?\C:\Windows\SoftwareDistribution\Download\dc17ef8048924c249952b719f3d2e8ad\windows10.0-kb5037016-x64-express.cab).
And so many other errors "Error - Overlap: Duplicate ownership for directory...... ", I have no words.
CBS Trusted Installer successfully registered to be restarted for pre-shutdown
CBS Trusted Installer is shutting down because: SHUTDOWN_REASON_AUTOSTOP
Now I rebooted and it is performing something, I don't understand, maybe something updated.
I will update you when he is finished.
