Unknown package error related to TLS issue

Learn
1

I recently released a package and tried using it in an old project. After trying to elm install the package I got the following error:

-- UNKNOWN PACKAGE -------------------------------------------------------------

I cannot find a package named name/package.

I could not connect to https://package.elm-lang.org though, so new packages may
have been published since I last updated my local cache of package names.

Looking through the locally cached names, the closest ones are:

    name1/package1
    name2/package2
    name3/package3
    name4/package4

Maybe you want one of these instead?

It seemed related to: Elm init tls issue

A fix was merged: elmPackages.elm: Fix runtime TLS connection to package.elm-lang.org by turboMaCk · Pull Request #414495 · NixOS/nixpkgs · GitHub . However, my devbox.lock for the project had an older version of the compiler.

"elmPackages.elm@latest": {
      "last_modified": "2025-05-06T08:06:31Z",
      "resolved": "github:NixOS/nixpkgs/1cb1c02a6b1b7cf67e3d7731cbbf327a53da9679#elmPackages.elm",
      "source": "devbox-search",
      "version": "0.19.1",
      "systems": {
	      ...
      }
}

That version didn’t have the fix: nixpkgs/pkgs/development/compilers/elm/packages/ghc9_6/default.nix at 1cb1c02a6b1b7cf67e3d7731cbbf327a53da9679 · NixOS/nixpkgs · GitHub

However, I checked elmPackages.elm | How to install with Nix or Devbox and the latest version found there did have the fix: nixpkgs/pkgs/development/compilers/elm/packages/ghc9_6/default.nix at a421ac6595024edcfbb1ef950a3712b89161c359 · NixOS/nixpkgs · GitHub

So, I updated elmPackages.elm in my devbox.lock.

devbox update elmPackages.elm

And, it solved the issue. Just sharing in case it could help someone else.
