EDIT: I managed to fix the issue myself. What I had to do was:
sudo dpkg --add-architecture i386 and sudo ubuntu-drivers install
Original Post:
I'm new to Ubuntu and Linux, so I don't really know what I'm doing. I'm using Ubuntu 20.04 LTS 64-bit. I've installed steam but now I cannot run it. When I put steam in the terminal I see the "Updating Steam" window for a split second before it closes. The terminal output looks like this:
cami@cami-pc:~/Downloads$ steam
Running Steam on ubuntu 20.04 64-bit
STEAM_RUNTIME is enabled automatically
Steam runtime environment up-to-date!
Steam client's requirements are satisfied

Looks like steam didn't shutdown cleanly, scheduling immediate update check
