Comment 7 for bug 1869842

Hi,

In this case, actual issue was transient and hit due to deployment moved forward even if repo setup failed in image build.

I will try to work further on one of the pending possible improvements:-

* It was expected all-nodes.sh[0] shouldn't have been executed if some package install fails in repo_setup.sh step. Like it did in eg: [1].
