Curl error when fetching file using http2

[ithinuel]

Describe the bug

Fetching a tarball from a URL prints several warning: error: messages

Steps To Reproduce

1. Copy this flake:

   {
   description = "A very basic flake";
   
   inputs = {
   nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";
   
   archive.url = "https://developer.arm.com/-/cdn-downloads/permalink/Fixed-Virtual-Platforms/FM-11.26/FVP_Base_RevC-2xAEMvA_11.26_11_Linux64.tgz";
   archive.type = "file";
   archive.flake = false;
   };
   
   outputs = { self, nixpkgs }: {
   packages.x86_64-linux.hello = nixpkgs.legacyPackages.x86_64-linux.hello;
   packages.x86_64-linux.default = self.packages.x86_64-linux.hello;
   };
   }

2. Run nix flake update

3. See it fetching everything fine

4. Run nix flake update

5. Prints:

   warning: error: unable to download 'https://developer.arm.com/-/cdn-downloads/permalink/Fixed-Virtual-Platforms/FM-11.26/FVP_Base_RevC-2xAEMvA_11.26_11_Linux64.tgz': HTTP error 200 (curl error: Failure when receiving data from the peer); retrying in 262 ms

Expected behavior

The command to execute without warning or error.

nix-env --version output

nix-env (Nix) 2.18.5

Additional context

Adding --option http2 false works around the issue but:

• nix-direnv only passes it to nix print-dev-env
• nix flake archive silently ignores it anyways because ignoring the client-specified setting 'http2', because it is a restricted setting and you are not a trusted user

Running with nix flake update --debug -v shows the following lines right before the warning: error::

curl: Failure writing output to destination, passed 60 returned 0
curl: process_pending_input: nghttp2_session_mem_recv() returned -902:The user callback function failed
curl: Connection #4 to host developer.arm.com left intact
finished download of 'https://developer.arm.com/-/cdn-downloads/permalink/Fixed-Virtual-Platforms/FM-11.26/FVP_Base_RevC-2xAEMvA_11.26_11_Linux64.tgz'; curl status = 56, HTTP status = 200, body = 0 bytes

My colleague hit this running Nix 2.24.6 in WSL2. It was resolvable by adding http2 = false to the nix.conf, but obviously that's a workaround— http2 connections should work.

Sounds like this could be a duplicate of #9664.
