High Sierra update fails

[kevthanewversi]

Pushing the High Sierra update to my client Macs fails even after setting a force install by date in Simian admin . I get the below log when I attempt to fetch updates. This is only started happening recently as I've been able to do prior Sierra updates. Just FYI, I have disabled automatic updates on the client Macs if it matters.

Command run on client Mac is > sudo managedsoftwareupdate --applesuspkgsonly -vvv

: managedsoftwareupdate is configured to process Apple Software Updates only.
