Switching to the Multi-user Installer
Welcome to the Multi-User Nix Installation
This installation tool will set up your computer with the Nix package
manager. This will happen in a few stages:
1. Make sure your computer doesn't already have Nix. If it does, I
will show you instructions on how to clean up your old install.
2. Show you what I am going to install and where. Then I will ask
if you are ready to continue.
3. Create the system users (uids [30001..30032]) and groups (gid 30000)
that the Nix daemon uses to run builds. To create system users
in a different range, exit and run this tool again with
NIX_FIRST_BUILD_UID set.
4. Perform the basic installation of the Nix files daemon.
5. Configure your shell to import special Nix Profile files, so you
can use Nix.
6. Start the Nix daemon.
Would you like to see a more detailed list of what I will do?
No TTY, assuming you would say yes :)
I will:
- make sure your computer doesn't already have Nix files
(if it does, I will tell you how to clean them up.)
- create local users (see the list above for the users I'll make)
- create a local group (nixbld)
- install Nix in /nix
- create a configuration file in /etc/nix
- set up the "default profile" by creating some Nix-related files in
/root
- back up /etc/bashrc to /etc/bashrc.backup-before-nix
- update /etc/bashrc to include some Nix configuration
- back up /etc/zshrc to /etc/zshrc.backup-before-nix
- update /etc/zshrc to include some Nix configuration
- back up /etc/bash.bashrc to /etc/bash.bashrc.backup-before-nix
- update /etc/bash.bashrc to include some Nix configuration
- load and start a service (at /etc/systemd/system/nix-daemon.service
and /etc/systemd/system/nix-daemon.socket) for nix-daemon

---- let's talk about sudo -----------------------------------------------------
This script is going to call sudo a lot. Normally, it would show you
exactly what commands it is running and why. However, the script is
run in a headless fashion, like this:
$ curl -L https://nixos.org/nix/install | sh
or maybe in a CI pipeline. Because of that, I'm going to skip the
verbose output in the interest of brevity.
If you would like to
see the output, try like this:
$ curl -L -o install-nix https://nixos.org/nix/install
$ sh ./install-nix
~~> Checking for artifacts of previous installs
Before I try to install, I'll check for signs Nix already is or has
been installed on this system.

Can you provide more details, like a coredump / backtrace? Anything special about your environment like LD_LIBRARY_PATH e.t.c. ?
