Home-manager: Error when running `nix-env -qa`

[asymmetric]

Since today, I get this error:

❯ nix-env -qa
error: cannot import '/nix/store/zsfkn004z6sdfmkwvxf7jpkrw64fjh9y-source', since path '/nix/store/2djwy3xymwh3890i1id73217144l8vas-source.drv' is not valid, at /nix/store/601wfd2qdr03mpj08cd4qr9lha7d63s4-home-manager-18.09/home-manager/tests/default.nix:14:1

I tried activating a previous generation, but that didn't help.

• NixOS 18.09
• HM 18.09

Hmm, that's an odd error. Could you attach the /nix/store/2djwy3xymwh3890i1id73217144l8vas-source.drv file in a comment? You could also try running

$ nix show-derivation /nix/store/2djwy3xymwh3890i1id73217144l8vas-source.drv
{
  "/nix/store/2djwy3xymwh3890i1id73217144l8vas-source.drv": {
    "outputs": {
      "out": {

      }
    },
    "inputSrcs": [

    ],
    …
  }
}

Oh, and you can try nix-env -f '<nixpkgs>' -qa. I just played around with this and there seems to be some oddity with the nix-env -qa command. For me I get

rycee@beta:~$ nix-env -qa

home-manager-install

It does not exist :man_shrugging:

nix-env -f '<nixpkgs>' -qa seems to work fine, thanks! Is this something that should be fixed in HM?

I'm not sure my problem is necessarily due to HM though.

[hrhino]

FWIW this is happening to me, too, on a relatively fresh nix setup. It worked fine until I ran nix-collect-garbage, though, which may or may not be related. Thanks for the -f workaround; I can use home-manager and nixos-rebuild just fine now. Let me know if I can share some information that could be useful.

[asymmetric]

I think my error too popped up after collecting garbage.

[schmittlauch]

Affected as well. I cannot say when the problem started to appear though, as this was the first time in several months I ran nix-env.

Just installed home-manager on a new NixOS install, same issue.

I just created my first generation, first I ran build then on switch I get this error:

This error was because I had installed packages with nix-env -iA package but also defined it in the home-manager configuration.

[asymmetric]

@ivegotasthma you mean that the nix-env -qa error is due to the package being installed declaratively and imperatively?

I thought getting into that state was actually not possible.

[ghost]

@asymmetric The -qa error is due to something else. I wanted to say that I fixed this issue:

error: packages '/nix/store/ignrjsw1bjji6qybmn4bd4h58ylb5ckj-home-manager-path/share/kxmlgui5/gvpart/gvpart.rc' and '/nix/store/a764d2md8nky868dmrms9b3im7cy2aji-gwenview-18.08.0/share/kxmlgui5/gvpart/gvpart.rc' have the same priority 5; use 'nix-env --set-flag priority NUMBER INSTALLED_PKGNAME' to change the priority of one of the conflicting packages (0 being the highest priority)

by removing the imperatively installed packages and using declaratively ones only.

[dorianr666]

I confirm this as well. Adding the repo, installing and using works fine - until you run garbage collect, then it starts complaining about the missing .drv file.

Removing home-manager and its repo makes nix-env work again.

[dashmoho]

Another workaround would be to run "nix-env -u", which would install some additional packages:

Sorry for the late action on this. Hopefully the issue is resolved now! Please reopen if not.
