Cannot install nix package manager without sudo privileges (lemmy.ml)

First of all, I'm completely new to Nix and I have no idea what I'm doing. I would like to use it initially as a more general purpose replacement of conda environments for my AI-development workflow. To begin with, I'd like to install nix package manager at my work server where I don't have root access. I tried

sh <(curl -L https://nixos.org/nix/install) --no-daemon

however it tries to create /nix which I cannot do without sudo. I searched everywhere, but I don't seem to find a way to circumvent this.

Thanks!

Nix has poor support for having a store path other than /nix/store. Your best bet is probably a helper like nix-portable, which uses Flatpack-like containers to emulate access to /nix

Thanks, this explains it. I'm trying to set up nix-portable now, but it's quite confusing. I downloaded nix-portable binary which is a self-extracting archive that silently unpacked a bunch of files to ~/.nix-portable:

$ ls ~/.nix-portable/bin/
bwrap  proot  zstd

It seems I was meant to run it like so ./nix-portable nix-shell but this does nothing. On my local machine running OpenSUSE Tumbleweed it exists immediately, whereas on my work HPC server it gets stuck.

Sorry, I don't have any practical advice on the topic, I only know the tool exists.

[–] suspectum@lemmy.ml 2 points 1 year ago

That's all right, thanks! It seems that it does do something indeed, I had to run with debug information and it was simply taking a long time to configure itself

NP_DEBUG=2 ./nix-portable nix-shell -p hello

The only issue is I downloaded a binary package which is dated early 2022 and it uses nix 2.5.1. I need to figure out how to force it to use the latest version of nix.
