First, find the name of the current [channel](@docroot@/command-ref/nix-channel.md) through which Nix is distributed: Check which Nix version will be installed, for example from one of the [release channels](http://channels.nixos.org/) such as `nixpkgs-unstable`:
```console ```console
$ nix-channel --list $ nix-shell -p nix -I nixpkgs=channel:nixpkgs-unstable --run "nix --version"
```
By default this should return an entry for Nixpkgs:
```console
nixpkgs https://nixos.org/channels/nixpkgs-23.05
```
Check which Nix version will be installed:
```console
$ nix-shell -p nix -I nixpkgs=channel:nixpkgs-23.11 --run "nix --version"
nix (Nix) 2.18.1 nix (Nix) 2.18.1
``` ```

Update the channel entry: ### Linux multi-user
```console ```console
$ nix-channel --remove nixpkgs $ sudo su
$ nix-channel --add https://nixos.org/channels/nixpkgs-23.11 nixpkgs # nix-env --install --file '<nixpkgs>' --attr nix cacert -I nixpkgs=channel:nixpkgs-unstable
# systemctl daemon-reload
# systemctl restart nix-daemon
``` ```
Multi-user Nix users on macOS can upgrade Nix by running: `sudo -i sh -c ## macOS multi-user
'nix-channel --update &&
nix-env --install --attr nixpkgs.nix &&
launchctl remove org.nixos.nix-daemon &&
launchctl load /Library/LaunchDaemons/org.nixos.nix-daemon.plist'`
Single-user installations of Nix should run this: `nix-channel --update; ```console
nix-env --install --attr nixpkgs.nix nixpkgs.cacert` $ sudo nix-env --install --file '<nixpkgs>' --attr nix -I nixpkgs=channel:nixpkgs-unstable
$ sudo launchctl remove org.nixos.nix-daemon
$ sudo launchctl load /Library/LaunchDaemons/org.nixos.nix-daemon.plist
```
Multi-user Nix users on Linux should run this with sudo: `nix-channel ## Single-user all platforms
--update; nix-env --install --attr nixpkgs.nix nixpkgs.cacert; systemctl
daemon-reload; systemctl restart nix-daemon` ```console
$ nix-env --install --file '<nixpkgs>' --attr nix cacert -I nixpkgs=channel:nixpkgs-unstable
```
