The next button fails due to a conditional test fails during the Package Selection stage.
Next fails because check_options invokes check_dependencies which needs to choose between two types of progress bars, and isinstance is passed a non-existant object variable rather then one that can actually be tested to be an instance of build_media.BuildMedia. Solved.
Failed on me again.
Tell me the selections you make
No longer fails, package sack was empty and therefore depsolving didn't successfully complete. Now at least adding a required package set.
