yeah, but if you install just discover, it shouldn’t be enough.
Your steps are the equivalent of installing discover from console, right? Like sudo pacman -S discover
Just doing this can lead to the installation of plasma discover frontend but not backend, therefore you obtain this error message from discover:
So there must be installed another one or few packages for the backend… that’s what I’m looking for.
Some of you knows which backend package(s) shoud I install?
