^ This is part of the output from trying to update.

I followed this “guide” https://linuxconfig.org/how-to-install-lutris-on-debian-10-buster

Seems like something went mildly wrong, Lutris works I’ve been able to install and play games the only thing that seems “wrong” is this output whenever trying to install something via “Discover” or trying to apt update.

Have I done something incorrectly? No googling returns similar results that I’ve found.

Use the actual commands from lutris’s download page for debian, not blindly copy pasting from some random linux blog.

Odd. Those are the same installation intructions…

So it would yield the exact same results.

Did… Did you read what I linked? I can understand that there are a lot of people posting here with the exact same issues.

But I get the feeling you didn’t even read my thread, you skimmed saw I got instructions from else where and wrote the entire thread off.

Why even bother replying?

EDIT/ The way it sits right now, the installation instructions for Debian are just… Wrong, or out of date. It fails to add the lutris repository entirely.

So again, whats up? How do I fix this?
