Hi, all: Is there anyone knows why "build-pkgs" and "build-iso" completed successfully and bootimage.iso created, but the target installer has below errors: (I have checked that "python36" and "python36-devel" are in dist/comps.xml and the type is "mandatory" of group ID "platform-controller", "platform-controller-worker", "platform-controller-worker-lowlatency", and the kickstarts cfg files include the related group in "%packages" ). Thanks. ======================================== Error The following software marked for installation has errors. This is likely caused by an error with your installation source.
