When you first install NixOS, you're automatically subscribed to the
|

NixOS channel that corresponds to your installation source. For

the `nixos-22.11` channel. To see which NixOS channel you're subscribed
|
||||
instance, if you installed from a 23.05 ISO, you will be subscribed to
|
||||
the `nixos-23.05` channel. To see which NixOS channel you're subscribed
|
||||
to, run the following as root:
|
||||
|
||||
```ShellSession
|
||||
# nix-channel --list | grep nixos
|

nixos https://nixos.org/channels/nixos-unstable
|
||||
nixos https://channels.nixos.org/nixos-unstable
|
||||
```
|

|

To switch to a different NixOS channel, do
|
||||
|
||||
```ShellSession
|
||||
# nix-channel --add https://nixos.org/channels/channel-name nixos

# nix-channel --add https://channels.nixos.org/channel-name nixos

(Be sure to include the `nixos` parameter at the end.) For instance, to

use the NixOS 22.11 stable channel:
|
||||
use the NixOS 23.05 stable channel:
|
||||
|
||||
```ShellSession
|

# nix-channel --add https://nixos.org/channels/nixos-22.11 nixos

# nix-channel --add https://channels.nixos.org/nixos-23.05 nixos

If you have a server, you may want to use the "small" channel instead:
