# Description

|
|
|
This command upgrades Nix to the stable version.
|
|
|
|
|
|
|
|
|
|
By default, the latest stable version is defined by Nixpkgs, 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 21:11:48 +01:00
|
|
|
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`).
