In changing from a 7.5 to 7.6 automated install. 7.6 is not happy and the
install process stops and shows the screen where the "Install Source" is
not happy. I enter 3 to see what its set for, I select network, I select
http and I see my URL that my kickstart file has. It looks right - but its
not happy.

I tried looking in other consoles (text mode) to see any error and nothing
is showing.   How do I see what the error is about the install source  ?
