I broke it. Again.

I’m so new. At first I just wanted to install discord on my fresh install of bazzite. It wouldn’t update any software and I could not get anything to install.

I’m running a very old pc. It’s got a 1050ti.
I don’t play demanding games but I also can’t keep running windows 7.

Here’s where I am currently. I have no idea what to do. Guide me, please?
