+
+ This version of Nixpkgs requires Nix >= ${requiredVersion}, please upgrade:
+
+ - If you are running NixOS, `nixos-rebuild' can be used to upgrade your system.
+
+ - Alternatively, with Nix > 2.0 `nix upgrade-nix' can be used to imperatively
+ upgrade Nix. You may use `nix-env --version' to check which version you have.
+
+ - If you installed Nix using the install script (https://nixos.org/nix/install),
+ it is safe to upgrade by running it again:
+
+ curl https://nixos.org/nix/install | sh
+
+ For more information, please see the NixOS release notes at
+ https://nixos.org/nixos/manual or locally at
+ ${toString ./nixos/doc/manual/release-notes}.
+
+ If you need further help, see https://nixos.org/nixos/support.html
