       error: Package ‘polipo-1.1.1’ in /nix/store/gl6fxkjcqa4794kgqpylr4kgy7lkqxiz-source/pkgs/by-name/po/polipo/package.nix:25 is marked as insecure, refusing to evaluate.


       Known issues:
        - Unmaintained upstream: https://github.com/jech/polipo/commit/4d42ca1b5849

       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 ‘polipo-1.1.1’ to
          `nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
          like so:

            {
              nixpkgs.config.permittedInsecurePackages = [
                "polipo-1.1.1"
              ];
            }

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
          ‘polipo-1.1.1’ to `permittedInsecurePackages` in
          ~/.config/nixpkgs/config.nix, like so:

            {
              permittedInsecurePackages = [
                "polipo-1.1.1"
              ];
            }
