So, I tried the archlinux method, but at some point it says that a bunch of files are corrupted and the signature for some people are unknown trust and it fails to commit transaction. In any case iirc pacman isn't supported on the steam deck because whatever you install will be erased any time you update...
I tried the all distributions method, but it says I don't have python 3.10.2; 2.7; 2.6; and python 2 when I try to run the program. I checked and I have python 3.10.2, and I can't install the other versions because all the guides say use the apt-get command, which returns a "can't find the command apt-get" error. And I can't find a python version manager on the discovery store, so I'm lost.
