When I try to run kodi with wayland in a cage session it core dumps since 25.11.

Dec 13 17:24:12 kodi systemd[1]: Started cage-tty1.service.Dec 13 17:24:12 kodi (cage)[1727]: pam_unix(cage:session): session opened for user kodi(uid=1000) by kodi(uid=0)

Dec 13 17:24:15 kodi systemd[1]: cage-tty1.service: Failed with result ‘core-dump’.

The kodi logs don’t show any usefull information:

How can I investigate this further?

you could provide some basic nix config and someone might look at it

personally i never ran it in cage… so i don’t know if i can personally help

It is basicly Kodi - NixOS Wiki, I also tried to disable all the plugins but that doesn’t make any difference.

{ pkgs, lib, config, ... }:
let
  kodi = pkgs.kodi-wayland.withPackages (kodiPkgs:
    with kodiPkgs; [
      inputstream-ffmpegdirect
      inputstream-adaptive
      keymap
      kodi-six
      pkgs.janitor
      pkgs.libraryautoupdate
      pkgs.retrospect
      six
      sponsorblock
      upnext
      youtube
    ]);
in {
  # Define a user account
  users.extraUsers.kodi = {
    isNormalUser = true;
  };

  services.cage = {
    user = "kodi";
    program = "${kodi}/bin/kodi-standalone";
    enable = true;
    environment = {
      PYTHONDONTWRITEBYTECODE =
        "1"; # should fix https://github.com/retrospect-addon/plugin.video.retrospect/issues/1923
    };
  };
  systemd.services."cage-tty1" = rec {
    after = [ "network-online.target" ];
    requires = after;
    restartIfChanged = lib.mkForce true;
  };

  networking.firewall.allowedTCPPorts = [ 8080 ];
}

could it be Startup crash on kodi for cage version v0.2.1 · Issue #456 · cage-kiosk/cage · GitHub ?

I reverted to 25.11 from unstable and now (the same config) works ok. So maybe it is this issue Startup crash on kodi for cage version v0.2.1 · Issue #456 · cage-kiosk/cage · GitHub

do you want to try upgrading your system again but building the old version of cage? it would be nice to know…
