@Addison said in Update Failed {SOLVED}:
I would need something to copy and paste to the command line for that.
Move the existing setup folder out of the way, then clone the latest setup version
cd mv RetroPie-Setup RetroPie-Setup.old git clone --depth=1 https://github.com/RetroPie/RetroPie-Setup.gitYou can then follow the installation instructions for @ExarKunIv's extra repository.
