Running both Dolphin and Ark 15.08.2 (Kubuntun Wily) I miss Ark service menus in Dolphin. They are not available in Settings -> Services. Ark package did write these files: ark_addtoservicemenu.desktop and ark_servicemenu.desktop into /usr/share/kservices5/ServiceMenus
Steps to Reproduce:
1. Open Dolhin and right-click zip archive
No "Extract Here" context menu
"Extract Here" context menu
I can use "Open with Ark" and proceed, so there's a work-around.
I too have the same issue, I can see that the file /usr/share/kservices5/ServiceMenus/ark_servicemenu.desktop" exists but in Dolphin's services configuration, I don't see any entry regarding extractions.
Thanks for the bug report. This is fixed in version 5.16 of the KIO framework, which will be released in a few days. Earlier versions of this framework lack the file konqpopupmenuplugin.desktop, which is required to make the context menu work properly. You might be able to work around this problem by installing this file manually, but the location where you have to put it can depend on the distro.
