Dolphin "Extract" menus missing in Kubuntu 15.10

in October 26, 2015

After upgrading from Kubuntu 15.04 to 15.10, I noticed that the "Extract" option was missing from right-click menus in Dolphin.

This is kind of serious issue for someone who downloads assets from clients or zip files from Github and the like.  The bug was identified well before the final freeze, so I'm left wondering as to how something seemingly so crucial was left out the final release.

After some quick searching and a visit to the Kubuntu Forums, I found a solution.

sudo ln -s /usr/share/kde4/servicetypes/konqpopupmenuplugin.desktop /usr/share/kservicetypes5/

Cheers to the guys who solved this, hope it works for anyone else with the issue.
