Installation starts right after we double click on the installation file 'citra-setup-windows.exe.' Just follow the instructions written in the screenshot below to finish the installation. Indicate the desired installation folder for the emulator.
Git is not installed in Ubuntu by default, so install git if it isn't installed already. Open the terminal and type: sudo apt install git cd /Downloads git clone -recursive The third command will create a new folder named citra in your Downloads directory which has 95.3MB of files in it. It will take a while to download, so wait until the download is completed and the terminal returns to the terminal prompt.
Then change directories to /Downloads/citra and try to install Citra again. Building Citra in debug mode using the gcc = version 5 is recommended.
The default gcc in Ubuntu 18.04 is gcc version 7.3.0.
