Issues building from USB key


I am new to redhat8 ( rocky8) linux and need some help from you. I am trying to build a system from USB bootable stick and a kickstart file.

I downloaded Rocky-8.5-x86_64-dvd1.iso , and created a bootable USB stick with the following command:

dd if=/home/itoufiqu/Downloads/Rocky-8.5-x86_64-dvd1.iso of=/dev/sdb status=progress

And I have my ks.cfg in a USB stick. So, I appended this in the command line:


It goes through initial screen and then fails on installation source (error setting up software source). I can see that my ks.cfg is read and copied to the system.

Does building Rocky Linux 8 from USB not work anymore? Or am I doing something wrong here? Or is there a separate process in Rocky Linux to build a system from USB bootable stick?

Any help or pointers to get this going would be very much appreciated.
