since there is no working help yet in the forum, I ask for it again:
I get:
error: Package ‘steam’ in /nix/store/xq7dppsz5prbxh8v7vrkswsydxaq594r-nixos-21.05.2478.a445f582988/nixos/pkgs/games/steam/steam.nix:42 has an unfree license (‘unfreeRedistributable’), refusing to evaluate.
even that I allowed unfree in /etc/nixos/configuration.nix
Has anyone an idea what to do

Sorry, I skimmed past that; could you share the contents of that? Assuming you did that correctly you shouldn’t get this error.
#allow unfree packages
nixpkgs.config.allowUnfree = true;
meanwhile I also changed to unstable, but did not help … 
Can you share your whole configuration.nix? That part of the config looks fine, but these things can be complex

looks like that : - )
now I have that as preformated text
How are you trying to install steam? If you’re not putting it in environment.systemPackages then nixpkgs.config.allowUnfree doesn’t apply. In those cases you need to use export NIXPKGS_ALLOW_UNFREE=1 in the shell where you run the command instead, like the manual suggests.
Are you using nix-env -iA? If so, I’d recommend forgetting that command exists. Put your permanent packages in environment.systemPackages instead.
sudo nix-env -iA nixos.steam
what does permanent packages mean ? how would I configure that ?
In your /etc/configuration.nix, where you currently have this:
Use this instead:
# List packages installed in system profile. To search, run:
# $ nix search
environment.systemPackages = with pkgs; [
bluefish
filezilla
firefox
steam
wget
];
Then rebuild your system configuration, and steam should be installed - using nix-env -iA is an anti-pattern in my opinion, because it side steps the declarative part of NixOS, which essentially defies the purpose of the distribution.
Oh, sorry, to also answer that, I just mean packages that are still installed after you reboot your computer, so for anything that you previously installed with nix-env -iA add it to your configuration.nix like above instead
ahhhhhhh coool I will be trying that, that makes sense !!!

thanks, it is installed now, still it does not run because:
Loaded SDL version 2.0.15-6655637
libGL error: MESA-LOADER: failed to open radeonsi: /run/opengl-driver-32/lib/dri/radeonsi_dri.so: cannot open shared object file: No such file or directory (search paths /run/opengl-driver-32/lib/dri)
libGL error: failed to load driver: radeonsi
but I do not want to bother you too much , no I got at least a step further.
No worries If you can’t figure it out, please open up a new post, someone will probably help sooner or later.
My initial thoughts are that maybe you need to add the correct drivers for your system to services.xserver.videoDrivers and reboot, or just reboot - but I’ll leave you to figuring it out.
Additionally to allowUnfree also enable programs.steam.enable in your system configuration, it will add staeam to environment.systemPackages and set some sane defaults for 32Bit libraries which are required to run Steam.
thanks for the hint 
, … **BTW where do one get all that knowledge **
about nixos config, is this just the manual or also
other sources to acquire from ?
I will be trying out, and open up a new topic , should I still not have
succeded.
