Installer failed

[Paul-Roux-Phys]

Hi all!

I'm having trouble re-installing nix on a macOS system.
I had a previous installation, then uninstalled it ungracefully with something stupid of the kind

rm -rf /nix
diskutil unmount /nix

and now I can't install nix again, I get the output shown below.
Any help would be welcome!

Platform

• Linux:
• macOS
• WSL

Additional information

I had a previous installation of nixos which I have ungracefully uninstalled

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 [351..382]) and groups (gid 350)
   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?

---- 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.

---- Found existing Nix volume -------------------------------------------------
  special:	disk1s7
     uuid:	5CF66956-FE5C-48AA-9DEC-015F59F8E405
encrypted:	yes

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

    $ sudo security find-generic-password -s 5CF66956-FE5C-48AA-9DEC-015F59F8E405 -w

to confirm keychain has a password that unlocks this volume


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

    $ sudo /usr/sbin/diskutil apfs unlockVolume disk1s7 -verify -stdinpassphrase -user 5CF66956-FE5C-48AA-9DEC-015F59F8E405

to confirm the password actually unlocks the volume

Verifying the specific cryptographic user 5CF66956-FE5C-48AA-9DEC-015F59F8E405 on APFS Volume disk1s7
Passphrase valid
Found a working decryption password in keychain :)


During install, I add 'nix' to /etc/synthetic.conf, which instructs
macOS to create an empty root directory for mounting the Nix volume.

Nix isn't the only thing in /var/folders/c9/_jvkx9hs0p389w3x3q8b19gr0000gn/T/tmp.BvYyTNr4/synthetic.conf.edit,
but I think I know how to edit it out.
Here's the diff:
+ nix
  run	private/var/run
Does the change above look right?
[y/n] y


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

    $ sudo cp /etc/synthetic.conf /var/folders/c9/_jvkx9hs0p389w3x3q8b19gr0000gn/T/tmp.BvYyTNr4/synthetic.conf.edit

remove nix from /var/folders/c9/_jvkx9hs0p389w3x3q8b19gr0000gn/T/tmp.BvYyTNr4/synthetic.conf.edit

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.

~~> Creating a Nix volume

---- sudo execution ------------------------------------------------------------

A few questions first :)

1. Did the rm command appear to actually remove a lot, or just spam you with a bunch of permission denied errors? (I assume it'd do the latter without sudo)
2. Why were you trying to uninstall? Were you getting "command not found" when trying to run nix commands? (likely after a macOS upgrade/update?)

If you just got permission spam and command not found errors, there may still be a working Nix on your system that is just missing from PATH (macOS updates have a bad habit of overwriting the shell hook the nix installer places in /etc/zshrc), and we might still be able to get it restored without a reinstall.

First, run diskutil info /nix to confirm the volume's mounted at the moment. (It's probably in this state from the installer run. If it's not, try rebooting and see if it's mounted afterwards.)

Once the volume's mounted, try running source '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh' and then see if your Nix commands are available and working. If they are, I'd just re-add the shell hook to /etc/zshrc as described in #3616 (comment). (You can also look at your local /etc/bashrc as a reference. Some people who don't need multi-user support work around this update problem by adding it to ~/.zshrc instead.)

If that doesn't work we'll sort out uninstall/reinstall.
