flk install broken since 3 days worth of nix update

NixOS/nix#4613 (comment)

https://github.com/NixOS/nixpkgs/blob/e30d87f22237fe25618136eb9f818ecefaeb02a9/nixos/modules/installer/tools/nixos-install.sh#L128

nix flake info -> nix flake metadata

Until upstream implements an anti corruption layer, it seems we are left with the task to do so.

Upstream Issue: NixOS/nix#4613

EDIT: just changing flake info -> flake metadata works. I tested it super-manually on my local setup, but have no idea how to properly wire this up in here (as an overlay?).

Was closed upstream by NixOS/nixpkgs#116807

So can we close this issue then?

I think, by an nixpkgs update to the flake.lock file, yes (nixpkgs-unstable, that will be shortly 😕 ), so essentially via #192

I think my issue is related.

How can one manually update? For instance I'm getting:

[devshell]$ flk razer switch
[sudo] password for cody: 
error: 'info' is not a recognised command
Try 'nix --help' for more information.

I see that flk switch is just:

sudo nixos-rebuild --flake "$DEVSHELL_ROOT#$1" "${@:2}"
[devshell] shell $ echo $DEVSHELL_ROOT
/home/cody/devos

So that gives:

sudo nixos-rebuild --flake "/home/cody/devos#razer" "${@:2}"

I think this:

[devshell]$ sudo nixos-rebuild --flake "/home/cody/devos#razer" switch
error: 'info' is not a recognised command
Try 'nix --help' for more information.

So... nixos-rebuild is broken for me? I think I can do a build and then switch to it in this case maybe? I'm not totally sure how to get out of this state.

Yeah I think there was a PR merged to update nixUnstable which now has a deprecated alias for nix flake info. As a workaround I believe you can do nix build /home/cody/devos#nixosConfigurations.razer.config.system.build.toplevel then ./result/bin/switch-to-configuration switch.

[nrdxp]

If the update broke nixos-rebuild for everyone, perhaps we should reprogram flk.sh to run nix shell ".#nixosConfigurations.${name}.config.system.build.toplevel" -c switch-to-configuration OPTION

Looks like it pays out well to have a flk wrapper. 👍

If someone is looking for a workaround for nixos-install, you can run the following cmd to patch it:
cp $(which nixos-install) . && sed -i 's@flake info@flake metadata@' ./nixos-install

This was a temporary issue.
