       error: Package ‘dotnet-sdk-6.0.428’ in /nix/store/y2gqh69ffs2bpnl3xwnhhznxp7xsca81-source/pkgs/development/compilers/dotnet/build-dotnet.nix:221 is marked as insecure, refusing to evaluate.


       Known issues:
        - Dotnet SDK 6.0.428 is EOL, please use 8.0 (LTS) or 9.0 (Current)

       You can install it anyway by allowing this package, using the
       following methods:

       a) To temporarily allow all insecure packages, you can use an environment
          variable for a single invocation of the nix tools:

            $ export NIXPKGS_ALLOW_INSECURE=1

          Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,
                then pass `--impure` in order to allow use of environment variables.

       b) for `nixos-rebuild` you can add ‘dotnet-sdk-6.0.428’ to
          `nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
          like so:

            {
              nixpkgs.config.permittedInsecurePackages = [
                "dotnet-sdk-6.0.428"
              ];
            }

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
          ‘dotnet-sdk-6.0.428’ to `permittedInsecurePackages` in
          ~/.config/nixpkgs/config.nix, like so:

            {
              permittedInsecurePackages = [
                "dotnet-sdk-6.0.428"
              ];
            }

       error: Package ‘spring-106.0’ in /nix/store/h9pi4ccchrlirn59scqvvz868nz0l42f-source/pkgs/games/spring/default.nix:96 is marked as broken, refusing to evaluate.

       a) To temporarily allow broken packages, you can use an environment variable
          for a single invocation of the nix tools.

            $ export NIXPKGS_ALLOW_BROKEN=1

          Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,
                then pass `--impure` in order to allow use of environment variables.

       b) For `nixos-rebuild` you can set
         { nixpkgs.config.allowBroken = true; }
       in configuration.nix to override this.

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
         { allowBroken = true; }
       to ~/.config/nixpkgs/config.nix.
