What distro are you running?

Arch

Which SteamOS Branch are you using?

Not Using a Steam Deck

What happened?

The boolean logic at the top of install.sh means that the prereq installation code never actually runs, as far as I can tell:

-if [ $linuxID != "ChimeraOS" ]; then
...
-elif [ $linuxID != "SteamOS" ]; then

This translates to "only run prerequisite checks for ChimeraOS", which doesn't seem like the desired behavior given the code there. It's a little unclear what the logic should be, but I'm guessing it's "run prerequisite checks for everything except SteamOS". Putting up a PR with that logic in a bit.
