Comment 5 for bug 1579551

this may or may not be useful info for debug, just sharing.
I've been helping someone get setup.
I helped them install the unity-scope-click, which took care of the problem.
however, while debugging another issue we discovered they had an odd version of ubuntu-app-launch (likely from an old silo), upon installing the correct version of ubuntu-app-launch the apps-scope went missing and required reinstalling unity-scope-click again.
