High Sierra installation failed

High Sierra installation is getting failed with"the operation could not be completed com.apple.OsinstallSetup/error.error 702" error message.

I downloaded the installer from Apple store and current OS Version is Sierra 10.12.6.

In logs(/var/logs/install.logs0, I can see the following error
