error: unexpected end-of-file

[Bruno Bigras]

It might have started to happen when I added ca-derivations ca-references to experimental-features. I'm already using nix-command flakes.

I have the same problem on my computer, but I'm only using flakes.

Run cachix/cachix-action@v10
Cachix: installing
  /usr/bin/bash -c nix-env --quiet -j8 -iA cachix -f https://cachix.org/api/v1/install
  error: unexpected end-of-file
  Error: Action failed with error: Error: The process '/usr/bin/bash' failed with exit code 1

Hey @bbigras does it still happen?

[Bruno Bigras]

Yes. On my computer and with github actions on 1 project:
https://github.com/bbigras/dendrite-demo-pinecone/runs/2869034346?check_suite_focus=true

Note that I don't have the problem on https://github.com/bbigras/nix-config/actions/runs/954487561 (I don't use ca-derivations ca-references for this one).

Also note that I can download and decompress https://cachix.org/api/v1/install just fine.

I'll look into this after lunch :)

This could be related: NixOS/nix#4903

Note that content addressable derivations aren't supported yet: cachix/cachix#373

[Domen Kožar]

Closing as it's a Nix issue: NixOS/nix#4977
