       error: Package ‘electron-25.9.0’ in /nix/store/50bgi74d890mpkp90w1jwc5g0dw4dccr-source/pkgs/development/tools/electron/binary/generic.nix:35 is marked as insecure, refusing to evaluate.


       Known issues:
        - Electron version 25.9.0 is EOL

       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 ‘electron-25.9.0’ to
          `nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
          like so:

            {
              nixpkgs.config.permittedInsecurePackages = [
                "electron-25.9.0"
              ];
            }

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
          ‘electron-25.9.0’ to `permittedInsecurePackages` in
          ~/.config/nixpkgs/config.nix, like so:

            {
              permittedInsecurePackages = [
                "electron-25.9.0"
              ];
            }
