After installing kcron 15.04.1 on opensuse 13.2, there is no option in systemsettings for task scheduler, even though there should be. Reproducible: Always
This might be the inverse of Bug#347028. kcron 15.04.1 (or higher) is the KF5 version, it only shows up in systemsettings5, not KDE4's systemsettings. Does it show up when you run "systemsettings5"? It does here.
PS: Or try "kcmshell5 kcm_cron".
I have solved this by changing `X-KDE-System-Settings-Parent-Category=system-administration` to `X-KDE-System-Settings-Parent-Category=session` "in /usr/share/kservices5/kcm_cron.desktop". Now kcron shows up under Session category.
So the problem is that there is no "system-administration" category in systemsettings.
(In reply to Daimonion from comment #4) > So the problem is that there is no "system-administration" category in > systemsettings. True, but openSUSE adds it in their packages, so this is not the reason for the reported problem here. As I wrote, I suspect that the OP ran KDE4's systemsettings (openSUSE 13.2 still uses KDE4 as default desktop), but installed the KF5 based kcron 15.04 from an additional repo. This cannot work, even if you add the "system-administration" category manually. Btw, a fix for the category problem has been suggested in https://bugs.kde.org/show_bug.cgi?id=347028#c5 Let's close this one...
