Installation on MacOS 13.1 fails (eDSRecordAlreadyExists)

[ghost]

Hi.

I tried to install Nix Package Manager on my iMac with Mac OS 13.1 (22C65). First it seems to run fine and then an eDSRecord pops up:

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.

Would you like to see a more detailed list of what I will do?
[y/n] y

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 to /nix
• create a configuration file in /etc/nix
• set up the "default profile" by creating some Nix-related files in
  /var/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
• create a Nix volume and a LaunchDaemon to mount it
• create a LaunchDaemon (at /Library/LaunchDaemons/org.nixos.nix-daemon.plist) for 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.

~~> 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 -u NONE -n /etc/synthetic.conf

to add Nix to /etc/synthetic.conf

Password:

~~> 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 disk1s8

to ensure the Nix volume is not mounted

disk1s8 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

~~> Encrypt the Nix volume

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

$ sudo /usr/sbin/diskutil mount Nix Store

to mount your Nix volume for encrypting

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 actually encrypt your Nix volume

Encrypting with the new "Disk" crypto user on disk1s8
The new "Disk" user will be the only one who has initial access to disk1s8
The new APFS crypto user UUID will be xxx-xxx-xxx-xxx-xxx
Encryption has likely completed due to AES hardware; see "diskutil apfs list"

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

$ sudo /usr/sbin/diskutil unmount force Nix Store

to unmount the encrypted volume

Volume Nix Store on disk1s8 force-unmounted

~~> Configuring LaunchDaemon to mount 'Nix Store'

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

$ sudo /usr/bin/ex -u NONE -n /Library/LaunchDaemons/org.nixos.darwin-store.plist

to install the Nix volume mounter

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

$ sudo launchctl bootstrap system /Library/LaunchDaemons/org.nixos.darwin-store.plist

to launch the Nix volume mounter

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

$ sudo launchctl kickstart -k system/org.nixos.darwin-store

to launch the Nix volume mounter

~~> Setting up the build group nixbld

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

$ sudo /usr/sbin/dseditgroup -o create -r Nix build group for nix-daemon -i 30000 nixbld

Create the Nix build group, nixbld

        Created:    Yes

~~> Setting up the build user _nixbld1

I am executing:

$ sudo /usr/bin/dscl . create /Users/_nixbld1 UniqueID 301

Creating the Nix build user (#1), _nixbld1

attribute status: eDSRecordAlreadyExists DS Error: -14135 (eDSRecordAlreadyExists)

---- oh no! --------------------------------------------------------------------
Oh no, 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.

Is this a bug or am I doing something wrong?

Sounds like you already have a user with the same UID (see #6153).

The easy workaround is deleting that user/users if you no longer use the software that needs them. If you still need them, there's an overview of how to find a different UID range and modify the installer in #6153 (comment)
