Build fails in single-user mode, but works with a daemon

[tilpner]

This issue is a result of @yurkobb's errors during nix-env -u.

# weird.nix
with import <nixpkgs> {};

stdenv.mkDerivation {
  name = "weird";
  src = fetchurl {
    url = https://newsboat.org/releases/2.15/newsboat-2.15.tar.xz;
    sha256 = "1dqdcp34jmphqf3d8ik0xdhg0s66nd5rky0y8y591nidq29wws6s";
  };

  phases = [ "unpackPhase" "installPhase" ];

  installPhase = "echo done > $out";
}

This derivation builds fine with a daemon, but not on a single-user installation or as root on a multi-user installation:

Note how it intends to build the same derivation both times, but succeeds only once. The error is identical for the single-user installation (done as non-root).

More -v doesn't seem to help either:

All interactive shells had tar and xz available, but that seems irrelevant because Nix seems to pick the path from <nix/config.nix>.

This was tested on nixpkgs master with Nix 2.2 on NixOS 19.03 and Ubuntu 18.04.

Weakly related. There used to be an attribute path that often failed on Hydra with

do not know how to unpack source archive

It was also an .xz file. It did not fail always though.
