Steam on Zorin 12

So I recently switched over from Win10 to Zorin 12, simply because my WIndows didn't work anymore and I wanted something new. Now that I am more or less set up, I want to be able to play my games again. And every time I run steam through the console, because I don't get any info otherwise, I get this:

Running Steam on zorin 12 64-bit
STEAM_RUNTIME is enabled automatically
Installing breakpad exception handler for appid(steam)/version(0)
libGL error: unable to load driver: radeonsi_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: radeonsi
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

Any ideas on how to fix that? I am new to all this so please keep it simple.
Thanks

Hi, look at the solution posted here:

Yes, it will mean using the Terminal (Menu | Utilities | Terminal or Ctlr+ Alt+ T)
