Please take a look at https://nixos.org/download.html first for basic installation instructions and read the relevant section in the Nix manual if you want to know more about how the install process works: https://nixos.org/manual/nix/stable/#ch-installing-binary.

== ~~Single-user install~~ ==

== Installation ==

Nix package manager can be installed as either:

~~=== Stable Nix ===~~

* Multi User Installation (recommended)

* Single User Installation

~~To install stable Nix from any Linux distribution, use the following two commands.~~ (~~Note: This assumes you have the permission to use <code>sudo</code>, and you are logged in as the user you want to install Nix for.~~)

<~~syntaxHighlight~~ lang="console">

=== Multi User Installation ===

$ ~~sudo install -d -m755 -o $~~(~~id -u) -g $(id -g) /nix~~

$ curl -L https://nixos.org/nix/install ~~| sh~~

$ bash <(curl -L https://nixos.org/nix/install) --daemon

</~~syntaxHighlight~~>

</syntaxhighlight>

~~Then don't forget to reboot or run the command provided at the end of the installation script to make nix available in your system:~~

=== Single User Installation ===

<~~syntaxHighlight~~ lang="console">

$ ~~source $HOME/.nix~~-~~profile~~/~~etc~~/~~profile~~.d/nix~~.sh~~

$ bash <(curl -L https://nixos.org/nix/install) --no-daemon

</~~syntaxHighlight~~>

</syntaxhighlight>

~~You may want to put this file directly in your ~/.bashrc or similar, so~~ Nix ~~would be available in any newly created shell.~~

=== Stable Nix ===

~~When~~ using ~~another shell like [https://fishshell.com Fish], you should ignore~~ the ~~previous procedure~~ and ~~use~~ the [~~https://github.com/jorgebucaran/fisher Fisher~~] ~~plugin [https://github.com/lilyball/nix-env.fish Nix-env~~].

By default, the rolling Nix package manager will be installed using one of the above commands and thus the <code>nixpkgs-unstable</code> [[Channel Branches|channel]] will be used.

~~After~~ that ~~being done,~~ you ~~can use all Nix commands as a normal user without any special permissions (for example by~~ using <~~code~~>~~sudo~~</~~code~~>).

Follow the below to switch to the stable channel:<syntaxhighlight lang="console">

$ sudo su

$ nix-channel --remove nixpkgs

$ nix-channel --add https://nixos.org/channel/nixos-25.11 nixpkgs

$ nix-channel --update

</syntaxhighlight>Then run the following command to verify that you are using the stable channel:<syntaxhighlight lang="console">

$ nix-shell -p nix-info --run "nix-info -m"

</syntaxhighlight>
