error: flake does not provide attribute

[iocron]

I've followed the readme instructions (I am using the nix-starter-config#standard version and I have a fresh nixos installation) and used sudo nixos-rebuild switch --flake .#nixos then I am getting the following error:

error: flake 'git+file:///home/mp/nix-config' does not provide attribute 'packages.x86_64-linux.nixosConfigurations."nixos".config.system.build.nixos-rebuild', 'legacyPackages.x86_64-linux.nixosConfigurations."nixos".config.system.build.nixos-rebuild' or 'nixosConfigurations."nixos".config.system.build.nixos-rebuild'

same here

[vaisakh@nixos:~/nix-config]$ sudo nixos-rebuild switch --flake .#hostname
warning: Git tree '/home/vaisakh/nix-config' is dirty
error: flake 'git+file:///home/vaisakh/nix-config' does not provide attribute 'packages.x86_64-linux.nixosConfigurations."hostname".config.system.build.nixos-rebuild', 'legacyPackages.x86_64-linux.nixosConfigurations."hostname".config.system.build.nixos-rebuild' or 'nixosConfigurations."hostname".config.system.build.nixos-rebuild'

sorry got it... in command

sudo nixos-rebuild switch --flake .#hostname

hostname should be replaced with our hostname, in my case

sudo nixos-rebuild switch --flake .#nixos
