[paul@nixos:~]$ sudo nixos-rebuild switch --show-trace

[paul@nixos:~]$

I can only guess I need to remove the tribler package.

Fixed on unstable: tribler: 7.11.0 -> 7.13.0 · NixOS/nixpkgs@fbd57b4 · GitHub

Considering the package is currently broken, that version bump should probably be backported (or the python version for this package downgraded). Try sending in a backport PR: https://github.com/NixOS/nixpkgs/blob/e4dbabf8541ab20f927c3497f6a44e1ea0aab2e3/CONTRIBUTING.md#how-to-backport-pull-requests

In the mean time, you could fix it downstream like this:

environment.systemPackages = [
  (pkgs.tribler.override { python3 = pkgs.python310; })
];

I commented out tribler package in /etc/nixos/configuration.nix, then nixos-rebuild switch worked (upgraded from 23.05 to 23.11), then removed the comment on tribler, and it seems to cause the same trace. So I guess this is a problem triggered by tribler. [tribler is a special torrent package]. I don’t know if this is a problem with tribler package… or just triggered by tribler.

The problem is caused by the python ecosystem. Since ~2019/2020 or so, python has adopted a new build standard that allows libraries to specify what python versions they support.

This has resulted in python package builders that are much more strict about allowing random libraries to run on more recent versions of python.

Since python (despite having minor releases) also constantly breaks backwards compatibility, and there are so many python libraries, this often means that random builds suddenly stop working if you update python.

The new NixOS release updated to python 3.11 by default, seems that until now nobody realized this breaks that random library, and tribler depends on it. You didn’t make any mistakes here, you just happen to be the first one to try tribbler on NixOS 23.11.

So the package is broken, and someone needs to fix it. You can do this yourself either upstream (on GitHub) or downstream (in your configuration.nix), or both.

The fix is either to downgrade the default python version for tribler (like I show above), or to update tribler to the latest version (since it no longer depends on the broken library).

5

There seems to exist a Python 3.10 version, and a Python 3.11 version of asynctest.
https://search.nixos.org/packages?channel=23.11&from=0&size=50&sort=relevance&type=packages&query=asynctest

So maybe tribler only needs to use the other version that it is using? (note, I am guessing it now use the 3.10 version)

I know almost nothing about nix packaging… just trying to follow/understand what you said.

6

Those are automatically generated packages in nixpkgs. There is no guarantee they work, even if it says python311.

python311Packages.asynctest is the exact same as python310Packages.asynctest, the difference is which python interpreter the nix package is bundled with.

Note I had a typo in my snippet, by the way, the python should be python3.

7

Actually, using:

(pkgs.tribler.override { python3 = pkgs.python310; })

It builds and install tribler, but on running it:

Hmm, well that’s annoying. Might be that this ends up with the wrong python because it no longer is just the default python3. Maybe you need:

environment.systemPackages = [
  (pkgs.tribler.override {
    python3 = pkgs.python310;
    libtorrent-rasterbar-1_2_x = pkgs.libtorrent-rasterbar-1_2_x.override {
      python = pkgs.python310;
    };
  })
];

That’s a wild guess though. In theory it should be getting a 2.x version of python, and you should be getting a warning about insecure packages. Might be simpler to just get someone to backport the tribler update at this point.

If that override works, do tell me, I’ll send a PR to fix the package upstream to do this correctly as well.
