How can I get a more verbose error message with nixos-rebuild

Help

I’m getting this:

This doesn’t really help me;)

I also run nixos-rebuild with -vv

All I’m trying to do is nixos-rebuild. Can it somehow point me to what part of my configuration.nix it’s not liking, so that I can remove it?

there is the --show-trace flag, maybe that helps

Nope, still shows exactly the same

I don’t understand how it can’t be possible to find out what’s causing this. I mean, it must be ultimately traceable if it happens when “something” is built. Where is “something”?:wink:

can I have a look at the code?

I don’t have it on a git repo, yet, so it’s a bit difficult, right now, since I can’t use my system.

I did, however, try to update the channels, and I get the same

sudo nix-channel --update
unpacking channels...
error:
       … while setting up the build environment

       error: getting attributes of path '/run/binfmt': No such file or directory
error: program '/nix/store/b9iwk28nd0h9z8gpyr3fcr1xjlwnavmc-nix-2.18.1/bin/nix-env' failed with exit code 1

, so this is something fubar.

You have a wrapper that contains binfmt which so broken. I would guess that you point it to a binary that doesn’t exist.

7

How about GitHub - maralorn/nix-output-monitor: Pipe your nix-build output through the nix-output-monitor a.k.a nom to get additional information while building.

ok, I found a solution.

  1. Create /run/binfmt
  2. Build and failboat
  3. rm /run/binfmt

Now all is dandy, but this is scary. It’s discomforting…

thanks;)

I’ll install this and have it ready the next time I run into something like this. Hopefully never;)

Thanks.
