How to install app in Fedora(Linux)?

Hello,
I am new to Fedora and I use the AlwaysOnPC thing on my iPhone.
I want to install "Toribash" but when I download the RPM it doesn't install it gives me an error saying:
"The name org.freedesktop.PackageKit was not provided by any .service files"
anyone could help?
Ii am not master of this because I am using always on PC app from the internet on my iPhone.
Thank You
