It did run on x86 linux box, so could just be an M1 issue with Docker.

Possibly, have not tested much on arm yet.

You could try passing -v to the cargo build in the container and see if something more useful pops out.

Getting the same issue, only happens on M1

Did anyone find a workaround for this? I have to make builds possible on M1/M2 hardware...

workaround

This should be an issue of Docker on Apple Silicon, not this docker image.

I solved the issue by using lima. The lima base image should be x86_64 beucase I had the same issue when using arch: "aarch64" in lima. I installed docker by How To Install and Use Docker on Ubuntu 22.04 | DigitalOcean.

arch: "x86_64"

images:
- location: "https://cloud-images.ubuntu.com/releases/22.04/release-20240126/ubuntu-22.04-server-cloudimg-amd64.img"
  arch: "x86_64"
  digest: "sha256:9f8a0d84b81a1d481aafca2337cb9f0c1fdf697239ac488177cf29c97d706c25"

mounts:
- location: "~"
- location: "/tmp/lima"
  writable: true

My workaround was to swap out and upgrade dependencies so as not to rely on ring. Latest releases of rustls use aws-lc-rc instead of ring by default
