   error: Package ‘qtwebkit-5.212.0-alpha4’ in /nix/store/s6r7ck2zgl8bh3k6sjjlpnsihh2c96sw-nixos-23.11/nixos/pkgs/development/libraries/qt-5/qtModule.nix:89 is marked as insecure, refusing to evaluate.


   Known issues:
    - QtWebkit upstream is unmaintained and receives no security updates, see https://blogs.gnome.org/mcatanzaro/2022/11/04/stop-using-qtwebkit/

   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 ‘qtwebkit-5.212.0-alpha4’ to
      `nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
      like so:

        {
          nixpkgs.config.permittedInsecurePackages = [
            "qtwebkit-5.212.0-alpha4"
          ];
        }

   c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
      ‘qtwebkit-5.212.0-alpha4’ to `permittedInsecurePackages` in
      ~/.config/nixpkgs/config.nix, like so:

        {
          permittedInsecurePackages = [
            "qtwebkit-5.212.0-alpha4"
          ];
        }
