[docker-in-docker]: fails for debian:bookworm (arch=arm64) - error: externally-managed-environment

[fex01]

• base image: "mcr.microsoft.com/devcontainers/base"
  • fails with: bookworm
  • successful with: bullseye
• host architecture: arm64 (Apple Silicon)

Error message seems to indicate a Python related problem, but installing a different Python version does not prevent the build failure. Same with different Docker versions. The only change influencing the build success is using either Debian bookworm or bullseye as base image.

Log: see below

35.22     If you wish to install a non-Debian-packaged Python package,

Hi 👋

Thanks for opening the issue, this looks related to #577
I should be able to fix the root cause soon.

Closing this as duplicate, feel free to use #577 for tracking.

@fex01 Can you try removing the version property in here and try again? That should help you get unblocked in the meanwhile, thanks!

Docker v2 should work fine with Debain:bookworm.
This worked for me 👇

{
	"image": "mcr.microsoft.com/devcontainers/base:bookworm",
	"features": {
		"ghcr.io/devcontainers/features/docker-in-docker:2": {
			"dockerDashComposeVersion": "v2"
		}
	}
}
