user groups - users wheel disk audio networkmanager

it's blocking issue since

$ sudo home-manager build
No configuration file found. Please create one at /root/.config/nixpkgs/home.nix

Resolved by adding myself to

nix.trustedUsers = [ "root" "@wheel" ];

I think this was mainly a case of poor error reporting in Home Manager. The fix I made changes

rycee@beta:/$ hm build
error: creating symlink from ‘/result.tmp-508-1612533748’ to ‘/nix/store/yp4phas300vg989lfcix0a5rhpjgrknq-home-manager-generation’: Permission denied

to

rycee@beta:/$ hm build
Cannot run build in read-only directory

which hopefully better indicates the problem. Thanks for reporting the issue!

Thank you

@rycee
That was pretty accurate, thank you.
If you have sudo, you can chmod 777 /path/of/your/repo/to/build, that was my solution.
Thanks to @rycee
