Just ran into the same problem when updating my system flake. For bisecting purposes, nixpkgs 61a8739e25aff217d3c706f376187398d10cd39c was my previous (working) configuration.

EDIT: bisection in progress, have to do some large builds now:

[bdb347b42cf507871d5b0c0a3bd632ba0cec8018] dbus: 1.14.0 -> 1.14.4

Excerpt from https://gitlab.freedesktop.org/dbus/dbus/-/blob/dbus-1.14.4/NEWS :

Behaviour changes:

• On Linux, dbus-daemon and other uses of DBusServer now create a
  path-based Unix socket, unix:path=..., when asked to listen on a
  unix:tmpdir=... address. This makes unix:tmpdir=... equivalent to
  unix:dir=... on all platforms.
  Previous versions would have created an abstract socket, unix:abstract=...,
  in this situation.

which seems to be the change that breaks python3Packages.dbus-next, so we probably need to file an upstream dbus-next issue.

[SFrijters]

https://github.com/altdesktop/python-dbus-next/issues/135

[archer-65]

As a workaround, something like this should work:

dbus = super.dbus.overrideAttrs (old: rec {
  version = "1.14.0";

  src = pkgs.fetchurl {
    url = "https://dbus.freedesktop.org/releases/dbus/dbus-${version}.tar.xz";
    sha256 = "sha256-zNfM43WW4KGVWP1mSNEnKrQ/AR2AyGNa6o/QutWK69Q=";
  };
});

Note that the downgrade would undo some security fixes; see PR #195264 ... which is also why we backported this problem to 22.05.

I see...I'll wait to re-enable qtile then

[SFrijters]

Depending on how much value you place on the failing test, something like this worked for me:

  pypkgs = (python3.override {
    packageOverrides = self: super: {
      # https://github.com/NixOS/nixpkgs/issues/197408
      dbus-next = super.dbus-next.overridePythonAttrs (old: {
        checkPhase = builtins.replaceStrings ["not test_peer_interface"] ["not test_peer_interface and not test_tcp_connection_with_forwarding"] old.checkPhase;
      });
    };
  }).pkgs;

Modifying the package in a general overlay triggered huge rebuilds for me, so I've just replaced it inside my maestral-qt derivation, which is what pulls in dbus-next in my system configuration.

[Panadestein]

@SFrijters How would you modify the package with a general overlay? Something like this didn't work for me:

(self: super: {
      python3 = super.python3.override {
         packageOverrides = pyself: pysuper: {
            dbus-next = pysuper.dbus-next.overridePythonAttrs (old: {
                checkPhase = builtins.replaceStrings ["not test_peer_interface"] ["not test_peer_interface and not test_tcp_connection_with_forwarding"] old.checkPhase;
            });
        };
     };
 })

[arjan-s]

This global overlay works for me, without annoying rebuilds:

self: super: {
  python3Packages = super.python3Packages.override {
    overrides = pfinal: pprev: {
      dbus-next = pprev.dbus-next.overridePythonAttrs (old: {
        # temporary fix for https://github.com/NixOS/nixpkgs/issues/197408
        checkPhase = builtins.replaceStrings ["not test_peer_interface"] ["not test_peer_interface and not test_tcp_connection_with_forwarding"] old.checkPhase;
      });
    };
  };
}

Note, I'm using flake-utils-plus and this is imported in sharedOverlays. I don't know if you can use it without modifications otherwise.

[SFrijters]

I have a similar setup, I have (minus the let bindings I have in my config):

nixpkgs.overlays = [
  (final: prev: {
    python3 = prev.python3.override {
      packageOverrides = self: super: {
        # https://github.com/NixOS/nixpkgs/issues/197408
        dbus-next = super.dbus-next.overridePythonAttrs (old: {
          checkPhase = builtins.replaceStrings ["not test_peer_interface"] ["not test_peer_interface and not test_tcp_connection_with_forwarding"] old.checkPhase;
        });
      };
    };
  })
   ...
];

@Panadestein So I don't see the difference between our configs...

[Panadestein]

Somehow, the overlay proposed by @arjan-s worked. This reaches about the limits of my Nix knowledge, but maybe python3Packages is required instead of simply python3? Is the only difference I can notice.
