Hello, just trying to get some help here. I'm fairly new to linux, and have tried a couple of different distros but I wanted to give debian a go. I just installed Trixie, and thought I'd follow this guide to get it set up nicely. The problem is that when I try to enable the extra repositories in sources.list and then update/upgrade I get all the warnings in the attached screenshot. I've followed the guide exactly and the author doesn't get these warnings when doing the update. The only thing I can think of is that they're using GNOME and I'm using KDE Plasma.

Can anyone give some pointers? TIA

Hello, hoping that someone will be able to help me here. I'm trying to get emulation to work on Lutris, but not having any luck. I've installed the Libretro runner and downloaded a SNES core for it. I've got the Chrono Trigger ROM set up, but when I try to run it, it says "no core has been selected for this game." I go into the game configuration and try to select a core under 'game options' but nothing happens when I click the core drop down menu.

Does anyone know what I'm doing wrong? Or if I should be using something else entirely?

TIA
