On ubuntu 21.04,I tried to install nix with this command :

ziomario@Z390-AORUS-PRO:~/Scaricati$ sudo curl -L https://nixos.org/nix/install | sh

[sudo] password for ziomario:

Note: a multi-user installation is possible. See https://nixos.org/nix/manual/#sect-multi-user-installation
performing a single-user installation of Nix...
copying Nix to /nix/store...

but I've got this error :

error: could not set permissions on '/nix/var/nix/profiles/per-user' to 755: Operation not permitted

I think that u already know that I can't install it as root.

As stated in the manual about single-user installations (which are done by default):

This will perform a single-user installation of Nix, meaning that /nix is owned by the invoking user. You should run this under your usual user account, not as root.

I'd remove /nix and try the install again, this time without using sudo.

I stumbled upon the same issue on Ubuntu 20.04 after installing Nix 2.8.1:

setser@machine:~$ nix doctor
error: could not set permissions on '/nix/var/nix/profiles/per-user' to 755: Operation not permitted

The permissions for this directory are already correct:

setser@jakku:~$ ls -la /nix/var/nix/profiles/
total 16
drwxr-xr-x 3 root root 4096 May 16 20:09 .
drwxr-xr-x 8 root root 4096 May 16 20:09 ..
lrwxrwxrwx 1 root root   14 May 16 20:09 default -> default-1-link
lrwxrwxrwx 1 root root   60 May 16 20:09 default-1-link -> /nix/store/jablffvlwqn3c1mnry4hpq5pnm4cz8mk-user-environment
drwxr-xr-x 3 root root 4096 May 16 20:09 per-user

Removing nix and reinstalling does not help.

Removing nix as described in manual and reinstalling helped, seems like something remained from previous nix installation.

I think it needs windows administrator access,

  1. Launch powershell as admin Right click on start then select power shell(admin)
  2. Launch wsl, type wsl in admin powershell
  3. Then use nix-shell

Which manual page do you mean?

cole-h commented 3 months ago

Probably this one: https://nix.dev/manual/nix/stable/installation/uninstall.html#uninstalling-nix
