i'm trying to setup dolphin emulator on ubuntu, as it was working fine on manjaro. the dolphin stable version is working fine but i need the development version for vulkan support i believe. tried inputting:
sudo apt-add-repository ppa:dolphin-emu/ppa
sudo apt update
sudo apt install dolphin-emu-master
as explained in dolphin wiki
but i get an error outputted: Unable to locate package dolphin-emu-master
kubuntu 20.04. the stable version installs just fine both via terminal and store GUI
