       error: Refusing to evaluate package 'radicle-node-1.10.3' in /nix/store/2g1ydkkflg5kl8hb1f8js0s0p9v4gl53-source/pkgs/by-name/ra/radicle-node/package.nix:164 because it is marked as insecure

       Known issues:
        - Private repositories are insecure: traffic between nodes is not encrypted and not authenticated.

       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 ‘radicle-node-1.10.3’ to
          `nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
          like so:

            {
              nixpkgs.config.permittedInsecurePackages = [
                "radicle-node-1.10.3"
              ];
            }

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
          ‘radicle-node-1.10.3’ to `permittedInsecurePackages` in
          ~/.config/nixpkgs/config.nix, like so:

            {
              permittedInsecurePackages = [
                "radicle-node-1.10.3"
              ];
            }
