Just a quick script that I wrote to fetch the latest versions of Proton GE.
Can be found here on my github: get_latest_proton_ge.
I also have this bash script to call this script loaded in my PATH.
cd /home/j/gits/get_latest_proton_ge/ poetry run python src/get_latest_proton_ge/get_latest_proton_ge.py
To use this just clone the repo, and then run a poetry install from inside the repository directory to populate the Python virtualenv.
Running get_proton anytime will fetch the latest version and install it. This is handier than typing all that out on the SteamDeck.
I also use it on my desktop.
