don't show channels in upgrade instructions 

channels make everything more stateful, and therefore more complicated
and potentially confusing, but aren't needed for this task, so don't encourage their use.

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
$ nix-channel --list
```
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-shell -p nix -I nixpkgs=channel:nixpkgs-unstable --run "nix --version"
nix (Nix) 2.18.1
```
> **Warning**

> Writing to the [local store](@docroot@/store/types/local-store.md) with a newer version of Nix, for example by building derivations with `nix-build` or `nix-store --realise`, may change the database schema!
> Writing to the [local store](@docroot@/store/types/local-store.md) with a newer version of Nix, for example by building derivations with [`nix-build`](@docroot@/command-ref/nix-build.md) or [`nix-store --realise`](@docroot@/command-ref/nix-store/realise.md), may change the database schema!
> Reverting to an older version of Nix may therefore require purging the store database before it can be used.
Update the channel entry:
### Linux multi-user
```console
$ nix-channel --remove nixpkgs
$ nix-channel --add https://nixos.org/channels/nixpkgs-23.11 nixpkgs
$ sudo su
# 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
'nix-channel --update &&
nix-env --install --attr nixpkgs.nix &&
launchctl remove org.nixos.nix-daemon &&
launchctl load /Library/LaunchDaemons/org.nixos.nix-daemon.plist'`
## macOS multi-user
Single-user installations of Nix should run this: `nix-channel --update;
nix-env --install --attr nixpkgs.nix nixpkgs.cacert`
```console
$ 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
--update; nix-env --install --attr nixpkgs.nix nixpkgs.cacert; systemctl
daemon-reload; systemctl restart nix-daemon`
## Single-user all platforms
```console
$ nix-env --install --file '<nixpkgs>' --attr nix cacert -I nixpkgs=channel:nixpkgs-unstable
```
