       a) To temporarily allow broken packages, you can use an environment variable

          for a single invocation of the nix tools.

            $ export NIXPKGS_ALLOW_BROKEN=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.allowBroken = true; }

       in configuration.nix to override this.

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add

       a) To temporarily allow broken packages, you can use an environment variable

          for a single invocation of the nix tools.

            $ export NIXPKGS_ALLOW_BROKEN=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.allowBroken = true; }

       in configuration.nix to override this.

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add

         { allowBroken = true; }

       to ~/.config/nixpkgs/config.nix.
