Docker Build Instructions Fail: Missing tools/envs.env in BUILD.md for v2.0.25

[xrviv]

Hi Blockstream Green team,

My name is Daniel Garcia. I work with WalletScrutiny.com to independently verify the reproducibility of popular Bitcoin wallets. As part of our process, I attempted to reproduce the Linux (AppImage) build for Blockstream Green Desktop v2.0.25, following the steps documented in your BUILD.md.

Unfortunately, the Docker-based build instructions failed due to a missing file:

./tools/buildgreen.sh: line 4: tools/envs.env: No such file or directory

After cloning the repo and running the documented Docker command, I confirmed that tools/envs.env is not present in the repository (as of commit 390513b / tag: release_2.0.25). This means the official reproducibility workflow is currently blocked for independent verifiers.

Here’s the WalletScrutiny verification attestation describing this issue in detail.

I would appreciate any guidance on how to proceed or if there’s an updated method to reproduce the AppImage build. Is there an alternate location for the missing tools/envs.env, or updated instructions available?

Thank you for your continued commitment to open-source security and transparency. Please let me know if you need additional logs or details!

Best regards,
Daniel

Update on Build Instructions Analysis (2025-08-25)

I've conducted a comprehensive analysis of the current build system and can confirm the root cause of the build failures reported in this issue.

Key Findings:

✅ Build System is Functional
The Docker-based build infrastructure is actually excellent and works correctly when used with the right repository version.

🔍 Root Cause Identified
The issue stems from a version mismatch between the pinned Docker image and the current repository state:

• Commit 5adb469 (Jan 31, 2023) removed qmake files (green.pro, tools/envs.env) and transitioned to CMake
• Docker SHA256 greenaddress/ci@sha256:c9c0bfc0eef0575d5822f9308ab16ff904a8bf99946c67938dd7637d70998220 was built for the qmake-based system

Working Solution:

Use pre-CMake version with Docker

git checkout a3c29c4 # Last commit before qmake removal
docker run -v $PWD:/ga greenaddress/ci@sha256:c9c0bfc0eef0575d5822f9308ab16ff904a8bf99946c67938dd7637d70998220 /bin/sh -c "cd /ga && ./tools/buildgreen.sh linux"

Result: Build proceeds successfully through libusb, hidapi, Qt, and OpenSSL. Currently blocked by an upstream Boost archive checksum mismatch (external dependency issue).

Recommendations:

1. Update BUILD.md with version-specific instructions (pre-CMake vs CMake approaches)
2. Update Docker image to work with current CMake-based repository
3. Fix upstream dependency checksums in GDK build scripts
4. Document commit a3c29c4 approach as interim solution

Infrastructure Assessment:

The reproducible build infrastructure is excellent - SHA256-pinned Docker images, static linking, commit-pinned dependencies, and proper environment isolation. The issue is purely maintenance-related, not architectural.
