Name
nix upgrade-nix - upgrade Nix to the latest stable version
Synopsis
nix upgrade-nix [option…]
Examples
|
• |
Upgrade Nix to the stable version declared in Nixpkgs: |
# nix upgrade-nix
|
• |
Upgrade Nix in a specific profile: |
# nix upgrade-nix --profile ~alice/.local/state/nix/profiles/profile
Description
This command upgrades Nix to the stable version.
By default, the latest stable version is defined by Nixpkgs, in 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 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).
