       error: Package ‘unarc-0-unstable-2020-06-05’ in /nix/store/jn0x7q8sg0qrby1fwnyvcb27npksc5bl-source/pkgs/by-name/un/unarc/package.nix:37 has an unfree license (‘unfree’), refusing to evaluate.

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

            $ export NIXPKGS_ALLOW_UNFREE=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.allowUnfree = true; }
       in configuration.nix to override this.

       Alternatively you can configure a predicate to allow specific packages:
         { nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
             "unarc"
           ];
         }

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

       error: Package ‘dcraw-9.28.0’ in /nix/store/79043gmgb25zbjgjy7rwhr111gyd7mfn-source/pkgs/by-name/dc/dcraw/package.nix:43 is marked as insecure, refusing to evaluate.


       Known issues:
        - CVE-2018-19655
        - CVE-2018-19565
        - CVE-2018-19566
        - CVE-2018-19567
        - CVE-2018-19568

       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 ‘dcraw-9.28.0’ to
          `nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
          like so:

            {
              nixpkgs.config.permittedInsecurePackages = [
                "dcraw-9.28.0"
              ];
            }

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
          ‘dcraw-9.28.0’ to `permittedInsecurePackages` in
          ~/.config/nixpkgs/config.nix, like so:

            {
              permittedInsecurePackages = [
                "dcraw-9.28.0"
              ];
            }
