Steps to reproduce

MacOS Monterey 12.2, zsh. I am reinstalling NIX.
My previous nix install cleanup script

sudo dscl . delete /Groups/nixbld

for x in {1..32}
do
sudo dscl . delete /Users/_nixbld$x
done

#sudo rm -Rfd /nix

if [[ -f /etc/bashrc.backup-before-nix ]] then
sudo rm /etc/bashrc
sudo mv /etc/bashrc.backup-before-nix /etc/bashrc
else
print "bashrc.backup-before-nix not found"
fi

if [[ -f /etc/bash.bashrc.backup-before-nix ]] then
sudo rm /etc/bash.bashrc
sudo mv /etc/bash.bashrc.backup-before-nix /etc/bash.bashrc
else
print "bash.bashrc.backup-before-nix not found"
fi

if [[ -f /etc/zshrc.backup-before-nix ]] then
sudo rm /etc/zshrc
sudo mv /etc/zshrc.backup-before-nix /etc/zshrc
else
print "zshrc.backup-before-nix not found"
fi

Then I run :

sh <(curl -L https://nixos.org/nix/install) --darwin-use-unencrypted-nix-store-volume

The script fails at this point :

I am executing:

$ sudo HOME=/var/root /nix/store/hw5v03wnc0k1pwgiyhblwlxb1fx5zyx8-nix-2.6.0/bin/nix-env -i /nix/store/hw5v03wnc0k1pwgiyhblwlxb1fx5zyx8-nix-2.6.0

to install a bootstrapping Nix in to the default profile

warning: the group 'nixbld
' specified in 'build-users-group' does not exist
installing 'nix-2.6.0'
error: the group 'nixbld
' specified in 'build-users-group' does not exist

A clear and concise description of what the bug is.

If you have a problem with a specific package or NixOS,
you probably want to file an issue at https://github.com/NixOS/nixpkgs/issues.

So I checked the users and groups.
The stated group nixbld exists. >> dscl . list /Groups | grep nix returns nixbld

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 and groups that the Nix daemon uses to run
    builds.

  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.

---- let's talk about sudo -----------------------------------------------------
This script is going to call sudo a lot. Every time I do, it'll
output exactly what it'll do, and why.

Just like this:

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo echo

to demonstrate how our sudo prompts look

This might look scary, but everything can be undone by running just a
few commands. I used to ask you to confirm each time sudo ran, but it
was too many times. Instead, I'll just ask you this one time:

Can I use sudo?
[y/n] y

Yay! Thanks! Let's get going!

~~> Fixing any leftover Nix volume state
Before I try to install, I'll check for any existing Nix volume config
and ask for your permission to remove it (so that the installer can
start fresh). I'll also ask for permission to fix any issues I spot.

During install, I add 'nix' to /etc/synthetic.conf, which instructs
macOS to create an empty root directory for mounting the Nix volume.
Can I remove /etc/synthetic.conf?
[y/n] y

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo rm /etc/synthetic.conf

to remove /etc/synthetic.conf

During install, I add '/nix' to /etc/fstab so that macOS knows what
mount options to use for the Nix volume.
Can I remove /etc/fstab?
[y/n] y

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo rm /etc/fstab

to remove /etc/fstab

The installer adds a LaunchDaemon to mount your Nix volume: org.nixos.darwin-store
Can I remove it?
[y/n] y

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo launchctl bootout system/org.nixos.darwin-store

to terminate the daemon

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo rm /Library/LaunchDaemons/org.nixos.darwin-store.plist

to remove the daemon definition

~~> 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.

---- Preparing a Nix volume ----------------------------------------------------
Nix traditionally stores its data in the root directory /nix, but
macOS now (starting in 10.15 Catalina) has a read-only root directory.
To support Nix, I will create a volume and configure macOS to mount it
at /nix.

~~> Configuring /etc/synthetic.conf to make a mount-point at /nix

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo /usr/bin/ex --noplugin /etc/synthetic.conf

to add Nix to /etc/synthetic.conf

~~> Creating a Nix volume

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo /usr/sbin/diskutil apfs addVolume disk1 APFS Nix Store -nomount

to create a new APFS volume 'Nix Store' on disk1

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo /usr/sbin/diskutil unmount force disk1s7

to ensure the Nix volume is not mounted

disk1s7 was already unmounted

~~> Configuring /etc/fstab to specify volume mount options

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo /usr/sbin/vifs

to add nix to fstab

Volume Nix Store on Nix Store mounted

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo /usr/bin/security -i

to add your Nix volume's password to Keychain

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo /usr/sbin/diskutil apfs encryptVolume Nix Store -user disk -stdinpassphrase

to encrypt your Nix volume

Encrypting with the new "Disk" crypto user on disk1s7
The new "Disk" user will be the only one who has initial access to disk1s7
The new APFS crypto user UUID will be 787D92F5-B3B0-49AB-B89E-DEF4FE89F9B3
Encryption has likely completed due to AES hardware; see "diskutil apfs list"
Volume Nix Store on disk1s7 force-unmounted

~~> Configuring LaunchDaemon to mount 'Nix Store'

---- sudo execution ------------------------------------------------------------
I am executing:

$ sudo /usr/bin/ex --noplugin /Library/LaunchDaemons/org.nixos.darwin-store.plist

Jeeze, something went wrong. If you can take all the output and open
an issue, we'd love to fix the problem so nobody else has this issue.

:(

We'd love to help if you need it.

  1. Why are you reinstalling Nix? Was something already wrong with the install?
  2. Please use some markdown formatting around code/log blocks in the future--it's very hard to read.
  3. I'm not really sure what's up with the group. There may be some lingering associations between the users and group that your script. It might help to gather some more information, but I'm not terribly familiar with Apple's group settings myself. I'd start with collecting output for:
    • dscl . list /Users UniqueID | grep nixbld | sort -n -k2
    • dscl . read /Users/_nixbld1
    • dscl . read /Groups/nixbld

For reference, here's what these 3 generate on my system (I can't swear it'll be the same--I'm still back on Catalina and my install is a little old):

FWIW, this also reminds me of another recently opened issue: #6035

It would be good to understand what's causing these, but if you're in a hurry you may also be able to follow the recommendations in that thread.

Hi, thank for the reply.

  1. Yes, I was having problems running nix-shell, but now that I think of it, was not a nix issue. That is why I was trying to reinstall. I am new to NIX.
  2. Yes, I agree, will do.
  3. Here are the outputs of those commands

P.S. I think I have just realised where the issue might be. Will test and let you know soon.

I have successfully reinstalled NIX, by doing ALL the steps stated in the MacOS uninstall instructions.
What I was not doing previously :

  1. Did not sudo rm ALL of the NIX files. Was doing only rm -rf /nix instead of
    '''sudo rm -rf /etc/nix /var/root/.nix-profile /var/root/.nix-defexpr /var/root/.nix-channels ~/.nix-profile ~/.nix-defexpr ~/.nix-channels'''

  2. Did not "Stop and remove the Nix daemon service"

  3. Did not "Remove the Nix Store volume" (did it only once but nothing differed)

  4. Did not always restart shell or Reboot...

I was also suspecting the /etc/nix/nix.conf setting build-users-group = nixbld
I might have had <U+2028> at the end of lines (copy pase issue)

Running uninstall script I threw together from the MacOS uninstall instructions solved the issue.
Had to remove all the hash symbols for posting here because of the formatting.

!/bin/zsh

if [[ -f  /etc/bashrc.backup-before-nix ]] then
        sudo rm /etc/bashrc
        sudo mv /etc/bashrc.backup-before-nix /etc/bashrc
else
        print "bashrc.backup-before-nix not found"
fi

if [[ -f /etc/bash.bashrc.backup-before-nix ]] then
        sudo rm /etc/bash.bashrc
        sudo mv /etc/bash.bashrc.backup-before-nix /etc/bash.bashrc
else
        print "bash.bashrc.backup-before-nix not found"
fi

if [[ -f /etc/zshrc.backup-before-nix ]] then
        sudo rm /etc/zshrc
        sudo mv /etc/zshrc.backup-before-nix /etc/zshrc
else
        print "zshrc.backup-before-nix not found"
fi

sudo nano /etc/synthetic.conf

sudo vifs

sudo launchctl unload /Library/LaunchDaemons/org.nixos.nix-daemon.plist
sudo rm /Library/LaunchDaemons/org.nixos.nix-daemon.plist
sudo launchctl unload /Library/LaunchDaemons/org.nixos.activate-system.plist
sudo rm /Library/LaunchDaemons/org.nixos.activate-system.plist

sudo rm -rf /etc/nix /var/root/.nix-profile /var/root/.nix-defexpr /var/root/.nix-channels ~/.nix-profile ~/.nix-defexpr ~/.nix-channels

sudo dscl . delete /Groups/nixbld

for x in {1..32}
do
sudo dscl . delete /Users/_nixbld$x
done

sudo diskutil apfs deleteVolume /nix

echo "Please reboot for changes to take effect"

Thank you

This is probably the root cause. I didn't see it, I don't think, when I looked at this from my laptop last night. But from my phone this morning I see an unrenderable box character appended to nixbld in your log/title. In this case, as long as your system is sorted, you can close the issue?

Edit: yes, just confirmed I don't see the character from laptop, but it is visible on my phone.
