nix install breaks on UID clash #6153

ikuz · 2022-02-24T04:12:57Z

Describe the bug

Tried to (re)install nix on mac os but it fails.

Steps To Reproduce

I followed instructions to remove a previous installation of nix: https://nixos.org/manual/nix/stable/installation/installing-binary.html

then did sh <(curl -L https://nixos.org/nix/install)

eventually it fails, because it looks like there are already _nixbld users on the system.

Log of the installation process:

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?

---- 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:	disk3s7
     uuid:	303B697C-12F9-41BC-8DC1-A4E8DAB0A5EC
encrypted:	no

---- warning! ------------------------------------------------------------------
FileVault is on, but your Nix Store volume isn't encrypted.

Should I encrypt it and add the decryption key to your keychain?
[y/n] y

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

Password:

---- 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 disk3s7
The new "Disk" user will be the only one who has initial access to disk3s7
The new APFS crypto user UUID will be 303B697C-12F9-41BC-8DC1-A4E8DAB0A5EC
Encryption has likely completed due to AES hardware; see "diskutil apfs list"
Volume Nix Store on disk3s7 force-unmounted

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.
I might be able to help you make this edit. Here's the diff:
  LABEL=Untitled none ntfs rw,auto,nobrowse
  # New NTFS HD:  on Wed 22 Apr 2015 11:21:27 EST
  LABEL= none ntfs rw,auto,nobrowse
- LABEL=Nix\040Store /nix apfs rw,nobrowse
Does the change above look right?
[y/n] y


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

    $ sudo /usr/sbin/vifs

to cut nix from fstab

patching file /etc/fstab

~~> 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.

Expected behavior

nix installed correctly

Additional context

Mac OS version 12.1

The text was updated successfully, but these errors were encountered:

ikuz · 2022-02-24T04:29:39Z

looking into this further, my system already has a user with UniqueID 301

ikuz · 2022-02-24T04:47:05Z

I ended up downloading the tarball, figuring out what user IDs are available on my system, modifying the appropriate file, and installing.

It would be nice to recognise this kind of fault and provide a suggestion for how to fix it.

abathur · 2022-02-24T18:27:04Z

I agree. Looks like it would detect a name clash but not a UID one. Can you update the title to mention the UID clash?

For anyone trying a fix:

The "best" fix would probably be to try and land the stalled overlapping work in WIP: Avoid using integer identifiers in install script #4346 (with modifications for the wrinkle Big Sur added). Since it is more focused on trying to avoid existing UIDs entirely, it should fix most instances of the error here (unless there aren't enough free UIDs), and avoid a user-unfriendly halt.

A narrow fix could probably add a poly_* function to run a UID check in this section, implement that function for the install-darwin-multi-user.sh and install-systemd-multi-user.sh scripts, and kick out a failure error along the lines of the name clash message already present.

nix/scripts/install-multi-user.sh

Lines 480 to 500 in cf7f984

    
               uid=$(nix_uid_for_core "$coreid") 
        
               task "Setting up the build user $username" 
        
               if ! poly_user_exists "$username"; then 
        
                   poly_create_build_user "$username" "$uid" "$coreid" 
        
                   row "           Created" "Yes" 
        
               else 
        
                   actual_uid=$(poly_user_id_get "$username") 
        
                   if [ "$actual_uid" != "$uid" ]; then 
        
                       failure <<EOF 
        
           It seems the build user $username already exists, but with the UID 
        
           with the UID '$actual_uid'. This script can't really handle that right 
        
           now, so I'm going to give up. 
        
           If you already created the users and you know they start from 
        
           $actual_uid and go up from there, you can edit this script and change 
        
           NIX_FIRST_BUILD_UID near the top of the file to $actual_uid and try 
        
           again. 
        
           EOF 
        
                   else

A better fix would probably be to perform both a name and UID check in validate_starting_assumptions here, using the for loop at the end of setup_report as a blueprint for how to iterate over the users. If we have to hard fail, it's best to do it before we've changed anything.

           Here's how to clean up the old backup file: 
        
           1. Back up (copy) $profile_target and $profile_target$PROFILE_BACKUP_SUFFIX 
        
              to another location, just in case. 
        
           2. Ensure $profile_target$PROFILE_BACKUP_SUFFIX does not have anything 
        
              Nix-related in it. If it does, something is probably quite 
        
              wrong. Please open an issue or get in touch immediately. 
        
           3. Once you confirm $profile_target is backed up and 
        
              $profile_target$PROFILE_BACKUP_SUFFIX doesn't mention Nix, run:

is too cryptic for me. How do I figure out what user IDs are available on my system and what are the appropriate files?

Why not just remove the offending user ids?

abathur · 2022-03-15T19:46:06Z

Not sure calling the comment by @ikuz cryptic will encourage them to provide more context...

How do I figure out what user IDs are available on my system

You can find answers to the basic how-do-I-check questions in #5928, where the reporter also mentioned a SonosDMS user.

and what are the appropriate files?

I suspect @ikuz is talking about downloading the installer tarball and editing it in line with the 2nd point in my comment at the end of #5928.

Why not just remove the offending user ids?

I don't think anyone will be able to answer this for you, because it's wrapped up in knowing what the user/UID are for and whether they are still in use. If the SonosDMS user is cruft from something you no longer use, removing it is probably fine. If not, removing it may break whatever uses it.

ikuz · 2022-03-15T21:55:38Z

Thanks @abathur. I'm including the detail here in case anyone else finds it useful

How do I figure out what user IDs are available on my system

I did

dscl . -list /Users UniqueID | sort -n -b -k 2

to get a sorted list of users and user IDs. Then I identified a suitable gap (of at least 32 ids) and used that as the range. (in my case the SonosDMS user had the conflicting ID 301 (and I didn't want to remove or change that in case it breaks my Sonos install), but there was a suitable gap from 302 onwards)

and what are the appropriate files?

I went to https://releases.nixos.org/ and browsed to find the tarball of nix that was relevant for my system (in my case it was
https://releases.nixos.org/nix/nix-2.6.1/nix-2.6.1-aarch64-darwin.tar.xz but nix versions have moved on since then, so that's not the newest nix anymore).

Then I unpacked the tarball and edited the install-darwin-multi-user.shfile. In my case I modified the NIX_FIRST_BUILD_UID line to be

NIX_FIRST_BUILD_UID="302"

Then I ran

 ./install

Note that running install failed several times for various reasons (typically due to files remaining after previous attempted installs). Each time I had to fix the problem and I had to manually clear out the _nixbld users that were created during the failed install. e.g.:

for i in `dscl . -list /Users  | grep nixb`; do echo $i; sudo dscl . delete /Users/$i; done

Eventually it succeeded.

Hope that's helpful.

idontgetoutmuch · 2022-03-16T11:39:26Z

@ikuz that's really helpful thanks - @abathur "cryptic for me" perhaps I should have said my brain is too small - the link to the previous ticket is also really helpful - I will report back when I get a chance to work on this again.

Thanks for your help @abathur and @ikuz - I managed to solve my problem by deleting nix, deleting the user that had grabbed the UID and reinstalling.

jyrimatti · 2022-04-27T07:25:10Z

Could someone maybe change the install script so that NIX_FIRST_BUILD_UID can be passed as an environment variable to override the default value? Or something similar. Maybe also add to installation instructions something like that dscl . -list /Users UniqueID | sort -n -b -k 2 can be used to check if the default value should be overridden.

I think having an existing UID of 301 is a company-wide problem for us, and it would be a lot easier to persuade people to use Nix if I could just say "Please install it with NIX_FIRST_BUILD_UID=351 sh <(curl -L https://nixos.org/nix/install) --daemon instead of the default recommendation" (or however that parameter should be passed in).

In the long run it would of course be better if the install script handled this whole thing automatically.

Tried to (re)install nix on mac os but it fails.

Ugh, it seems darwin uses a different code path:

$ git grep NIX_FIRST_BUILD_UID
scripts/bigsur-nixbld-user-migration.sh:((NEW_NIX_FIRST_BUILD_UID=301))
scripts/bigsur-nixbld-user-migration.sh:        ((next_id=NEW_NIX_FIRST_BUILD_UID))
scripts/install-darwin-multi-user.sh:NIX_FIRST_BUILD_UID="301"
scripts/install-multi-user.sh:NIX_FIRST_BUILD_UID="${NIX_FIRST_BUILD_UID:-30001}"
scripts/install-multi-user.sh:    echo $((NIX_FIRST_BUILD_UID + $1 - 1))
scripts/install-multi-user.sh:NIX_FIRST_BUILD_UID near the top of the file to $actual_uid and try

Similar to f4d57aa ("installer: allow overriding nix user GID and UIDs"), but for darwin. (There's no corresponding *_GID in this script though, so skipping that.) Ref NixOS#6153.

On Ventura, with the system-installed grep, @ikuz 's one-liner to remove existing users did not work for me. I had to use:

for i in `dscl . -list /Users  | grep -h nixb -`; do echo $i; sudo dscl . delete /Users/$i; done

(the difference is the inclusion of the -h flag)

After that, running my modified ./install worked correctly!

Hi @bjornfor Is there any plan to upstream your fix?

Hi @bjornfor Is there any plan to upstream your fix?

I don't have anything other than the draft above, and don't have a good solution/time to fix it so that it can be integrated.

caldwell · 2023-03-06T01:09:50Z

I just got bit by this. In my case there was a "SonosDMS" user at 301—looks like some vestige of an old install. I just deleted the user to get past it (since I haven't used a Sonos product in years). The rest of the install worked fine.

Could we both have a configurable first user id and if not provided, try incrementing uids until we either find an open block that can be used or fail if we are going to exceed the maximum number of uids?

joshryandavis · 2024-06-10T22:19:10Z

might run into this on macOS 15.

301 occupied by new daemon

AppleMetaNodeLocation: /Local/Default
GeneratedUID: ABCDEFAB-CDEF-ABCD-EFAB-CDEF0000012D
GroupMembers: FFFFEEEE-DDDD-CCCC-BBBB-AAAA0000012D
GroupMembership: _modelmanagerd
Password: *
PrimaryGroupID: 301
RealName:
 Model Manager
RecordName: _modelmanagerd
RecordType: dsRecTypeStandard:Groups

abathur · 2024-06-10T22:47:26Z

IIRC we still use 30000 as the gid and only use 301 as a uid.

fbettag · 2024-06-11T17:34:15Z

yup same here

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

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

abathur · 2024-06-11T18:29:34Z

Egh--I guess that's both a UID and GID :)

Can you survey the ID space to see what contiguous ranges are open? I think maybe cat /etc/passwd will show them.

We picked 301+ since it seemed like Apple focused on the 200 range. I'm hoping they've just filled it and are spilling over (and not, say, sprawling out over the 200-400 service user range and leaving us no good contiguous block).

Hopefully we can just move new installs up to 360 or something. IDK.

@cole-h Do you recall whether the detsys installer is sensitive to this same issue, or does it just skip UIDs that are taken?

fbettag · 2024-06-11T19:45:31Z

The last few are these here:

_aonsensed:*:300:300:Always On Sense Daemon:/var/db/aonsensed:/usr/bin/false
_modelmanagerd:*:301:301:Model Manager:/var/db/modelmanagerd:/usr/bin/false
_reportsystemmemory:*:302:302:ReportSystemMemory:/var/empty:/usr/bin/false
_swtransparencyd:*:303:303:Software Transparency Services:/var/db/swtransparencyd:/usr/bin/false
_naturallanguaged:*:304:304:Natural Language Services:/var/db/com.apple.naturallanguaged:/usr/bin/false
_oahd:*:441:441:OAH Daemon:/var/empty:/usr/bin/false

Maybe go 450+?

abathur · 2024-06-11T19:52:23Z

Opened up a dedicated issue to track this.

michaelvanstraten · 2024-06-12T11:14:37Z

To repeat @ikuz's solution again:

For a quick fix on macOS 15 install/reinstall with:

 NIX_FIRST_BUILD_UID="305" sh <(curl -L https://nixos.org/nix/install)

niklasravnsborg · 2024-06-20T07:49:32Z

@michaelvanstraten After upgrade to macOS 15, I've run your suggested command but get the following error:

It seems the build user _nixbld1 already exists, but with the UID
with the UID ''. This script can't really handle that right
now, so I'm going to give up.

If you already created the users and you know they start from
 and go up from there, you can edit this script and change
NIX_FIRST_BUILD_UID near the top of the file to  and try
again.

Did you experience something similar?

michaelvanstraten · 2024-06-20T07:52:20Z

@niklasravnsborg you can try the following with caution:

for u in $(sudo dscl . -list /Users | grep _nixbld); do sudo dscl . -delete /Users/$u; done

niklasravnsborg · 2024-06-20T13:01:31Z

for u in $(sudo dscl . -list /Users | grep _nixbld); do sudo dscl . -delete /Users/$u; done

Awesome, that did the trick for me regarding the nix installation :) Thank you
