If there is a situation where skip broken bail out then please check the upstream yum version to help make it better.

Commands:

My Apps Lists are long and can take 2 or 3 hours on my High Speed (18mbps) Internet Connection. But, it saves weeks of work. Since it took me a long time to Research and Install each App Separately...
