# Description
This command upgrades Nix to the stable version declared in Nixpkgs.
This stable version is defined in [nix-fallback-paths.nix](https://github.com/NixOS/nixpkgs/raw/master/nixos/modules/installer/tools/nix-fallback-paths.nix)
and updated manually. It may not always be the latest tagged release.
By default, it locates the directory containing the `nix` binary in the `$PATH`
2020-12-09 20:11:48 +00:00
environment variable. If that directory is a Nix profile, it will
upgrade the `nix` package in that profile to the latest stable binary
release.
You cannot use this command to upgrade Nix in the system profile of a
NixOS system (that is, if `nix` is found in `/run/current-system`).
