1 signature not checked due to a missing key
OK
soo what do i do

Hi, try just wget -q https://download.opensuse.org/repositories/home:/strycore/Debian_9.0/Release.key -O-
is the key downloaded/displayed, do You have wget installed?
BTW this is only adding key not lutris install command, but You know that?

i know its not the install command for lutris but it cant find it
sudo apt-get install lutris
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to locate package lutris
i thought it was the fact it cant find the is the problem

Did You add lutris repository as in instructions?
Please give some outputs as i said in my first post.
1.add repository
2.add release key (if not working try as i described in my post, what the result)
3. try install lutris

pi@cnat:~ $ echo “deb http://download.opensuse.org/repositories/home:/strycore/Debian_9.0/ ./” | sudo tee /etc/apt/sources.list.d/lutris.list
deb http://download.opensuse.org/repositories/home:/strycore/Debian_9.0/ ./

so i cant post the commonand line for 1 reason do you know anywhere i can find help with this where i can post what is goin on

Maybe its flagged because You didn’t provide any info about what You did, what was the output of the command You run (not the command itself) as states in: Please read before asking for help
Did You run:

sudo apt-get update

is very important before trying to install.
