So after many years of developing with NodeMCU boards I finally took the step into Raspberry PI.
got an RPI 4B from my uncle.
I've installed libreelec with kodi using the supplied windows installer tool. I've used an 8GB micro SD card. put into the rpi and started it. resizing: done! everything worked fine. it booted. BUT I can't install any addons. I have internet access, an IP is assigned successfully and I can connect with the RPI app or SSH.
But I can't install any addons. they show up, there's a long list. when I click on install it shows the dependenies info thingy and I click install again. but then a popup message appears in kodi on the upper right saying "Installation failed". I've googled my butt off and can't find any solution. I've clean formatted the sd card and installed again downloading the image file again. problem remains. I'm controlling it via CEC remote btw. right now I'm just fed up with Linux again xD I mean it's a stable release and I've followed all instructions correctly. it's an official widely used device. and it just doesn't work lol. linux..
