@MeduZaPaT Will I be able to use the PPA that is listed on the wiki deployment page? It seems like it is from 2020 so I'm concerned it is out of date.

I am using the pi4 with retropie. When I install, do I just need to go about it manually (build)? Was using the PPA even an option for me?

I apologize for such basic questions. Linux has a lot of unknowns to me.
