Hello, I am trying to create a local rhel8 repository for testing purposes on my local lab. I know this is not the most efficient way to access the software. I'm just doing this as preparation for the RHCSA exam. My current setup is a macbook pro running vmware fusion. I have rhel8 running in a vm. I loaded the OS using a .iso I downloaded from redhat. I am trying to get the .iso mounted so that i can create a local yum repository. Here is the command I tried:

dd if=/dev/sr0 of=/rhel.iso bs=1M

Since my iso is not on a mounted CD it is failing. Can someone point me in the right direction?
