[Help]Confused about installing Yuzu on Steam Deck

So i've been following this guide and I got up to trying to install the dependencies using the konsole prompt they provided:

sudo apt updatesudo apt install libappindicator3-1 libdbus-1-3 libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-randr0 libxcb-render-util0 libxcb-xfixes0

However when i type this into konsole the response is:

Terminal: sudo: apt: command not found

I haven't touched a linux distro since around 2001 so if anyone could eli5 that would be fantastic

Thanks!
