Download RetroPie

Update and upgrade the existing APT packages:

sudo apt update && sudo apt upgrade

Install the needed packages for the RetroPie setup script:

sudo apt install -y git dialog unzip xmlstarlet

NOTE: if you get any errors about any package not being found and you're using Ubuntu, make sure the universe APT repository has been added and enabled on the system by running sudo add-apt-repository universe and then starting again with the previous step.

Download the latest RetroPie setup script:

git clone --depth=1 https://github.com/RetroPie/RetroPie-Setup.git

Enter the folder with the setup script:

cd RetroPie-Setup

The script is executed with:

sudo ./retropie_setup.sh

The screen should then appear like this:

sudo ./retropie_setup.sh<----- 이부분에서 막힙니다..

터미널에서 호환이 안된다고 나오네요.

리눅스 민트에서는 잘됩니다..

조언 부탁드립니다.
