Build ISO with mkisofs

Posted on

I am trying to build a RHEL 8-10 ISO with a basic web server (will add more later) to allow easier deployment. However, my system does not recognize any of the repositories that are specified in my ks.cfg file. See image. The Installation Summary GUI reports back Installation Source "Error setting up base repository" But when I click, I see the respositories, but cannot do anything with them.

I have downloaded all the repositories that I need in OEMDRV directory.
I ran createrepo_c to build it the respository.

I am building this on Ubuntu 22.04 Workstation. I tried everything, but, cannot seem to get this working. I am needing help.
