  The installation was stopped due to incomplete spokes detected while running in non-interactive cmdline mode. Since there cannot be any questions in cmdline mode, edit your kickstart file and retry installation.
  The exact error message is: 
  
  The following mandatory spokes are not completed:
  Installation Destination.
  
  The installer will now terminate.
