Yeah I’m doing the same, I even tried to import a nonexistent file, and use build like you instead of switch, but I’m only getting the error from above.

What’s your nix version?

nix (Nix) 2.34.6

I think we’re doing different things, that’s why it’s giving us completely different errors.

I just added files to imports in configuration.nix

I’m guessing you’ve got some manual error checking implemented with assertions?

       (stack trace truncated; use '--show-trace' to show the full, detailed trace)

       error: Path 'nix/bobo/test.nix' does not exist in Git repository "/home/bobo/dotfiles".
Command 'nix --extra-experimental-features 'nix-command flakes' build --print-out-paths '/home/bobo/dotfiles/nix#nixosConfigurations."bobo".config.system.build.nixos-rebuild' --no-link' returned non-zero exit status 1.

I can often only try to guess what’s wrong by reading the stacktrace top-to-bottom, so I’ve somewhat gotten used to doing that.

I’m yet to see any nix error be more readable top to bottom. And I think it’s intentionally designed that way so you don’t need to scroll up.

I actually thought, it said somewhere in there, that the file isn’t staged, but apparently not even that (anymore?).

It’s a different error. To me it looks like you tried to import a file that doesn’t exist. I made the file correctly and imported it, just didn’t git add it. After committing I switched without issues.

Only the modules/terminal/new_file.nix in the second-last line is relevant.

For me that error message was in the same spot. The rest of the trace is what was evaled so you got to that error. It’s the same principle as stack trace in other languages.

You don’t happen to be using Lix or something, do you?

No, unstable nixos + home-manager. The error above was from

sudo nixos-rebuild switch --flake ...

For me there was only 1 line beneath that error, it’s more visible than the warning. Maybe they improved it, or you started reading from the top?

I just completely forgot about that error because I have an extremely basic config.

Fortunately, your comment is not relevant at all since I incorrectly posted the warning instead of the explicit error:

error: Path 'path/to/file' in the repository "/path/to/repo" is not tracked by Git.

It even gives you

To make it visible to Nix, run:

git -C "/path/to/repo" add "path/to/file"

random pile of unclear errors

warning: Git tree ‘/path/to/repo’ is dirty

No candles, but I do light up a torch wink wink

Do you have any snaps installed? Each one slows down your boot time because every snap is virtually mounted on boot.

You think you don’t have any snaps? Ubuntu hijacks apt commands to install snaps.

You removed snaps completely from your system to avoid that? Ubuntu reinstalls it after an update.

And that’s besides the fact you’re trusting a closed source app store that’s managed by scum who sold user data to Amazon. They can literally add whatever spyware they want to FOSS and you won’t know it. And considering how many people accused them of illegally harvesting data through Azure Ubuntu images…

What am I doing wrong here?

Ubuntu on a desktop

No, the NATO allies all work together to catch each other’s dissidents

Ah yes, well known dissidents like

checks notes

Angela Merkel and other EU officials

Meanwhile in Denmark

In August 2020, Trine Bramsen who was recently appointed Danish minister of defence in June of the previous year was told of the operation, following which agency head Lars Findsen and three other officials were suspended.[7]

Isn’t it public info that the USA has backdoors in every CPU (IME for example), or that NSA collects literally every piece of data going to and from USA, or that the USA illegally spies on its allies in the NATO by tapping phones and transcontinental internet cables? Or that trump literally called for Snowden to be executed for making all of that public?

If it’s burbling, you fucked up.
