- Missing files / packages mentioned:
- pubspec.lock is not found in the build context for the COPY step.
- .dockerignore is excluding pubspec.lock (CopyIgnoredFile warning: "Attempting to Copy file \"pubspec.lock\" that is excluded by .dockerignore (line 44)")
- Version mismatch / base image information:
- The build references two different Ubuntu bases in the multi-stage Dockerfile:
- Stage showing: FROM docker.io/library/ubuntu:22.04@sha256:ce4a593b4e323dcc3dd728e397e0a866a1bf516a1b7c31d6aa06991baec4f2e0

This indicates a mismatch between ubuntu:jammy-20260217 and ubuntu:22.04 bases used in the build.FROM ubuntu:22.04

Summary (under 1500 chars) - Exact error message and exit code - Could not find compiler set in environment variable CXX: - clang++. - CMAKE_CXX_COMPILER not set, after EnableLanguage - Unable to generate build files - The step failed with exit code 1 during the Flutter/Linux build attempt. - Failing command/step - [12/13] RUN flutter build linux --release - Missing packages or files mentioned - The error indicates the CXX environment variable is set to clang++, but the clang++ compiler is not installed or not found. Missing package: clang++ (i.e., clang or a clang++ binary in PATH). The build attempted to use clang++ via CXX, but could not locate a compiler. - Version mismatch information - Flutter toolchain: nightly build (nightly-2024-12-02) with Flutter 3.43.0-1.0.pre-204 on branch master; Engine: e31d8993…; Dart 3.12.0 - This is a Flutter/Linux desktop build; the CMake failure occurs before compilation, due to the missing CXX compiler rather than a Flutter version mismatch.

Concerns: The AppImage tool download line uses curl -JOL without following redirects (-L); this will fail if the GitHub URL redirects. Use curl -L -O or curl -L -J -O for redirects., The build script assumes the Flutter Linux desktop binary is at /app/build/linux/x64/release/bundle/jasmine; if the app name changes, or Flutter output path differs, the run script may not locate the executable., The Dockerfile contains multiple COPY instructions but also copies the entire repo; consider narrowing the build context to avoid shipping large or unnecessary files into the image.

Summary (actionable items preserved)
- VerifyBuild status: build_failed
- Build concerns: large image size/time due to Flutter and Rust toolchains on Ubuntu 22.04; no non-root user configured; AppImage tooling included but not required for Linux desktop Flutter app.
- Failing step: RUN flutter build linux --release (step 12/13)
- Exit code: 1
- Docker: Dockerfile:50
- Build log termination: ERROR: failed to build: failed to solve: process "/bin/sh -c flutter build linux --release" did not complete successfully: exit code: 1
Exact errors (preserved verbatim):
- lib/configs/theme.dart:71:24: Error: The argument type 'BottomAppBarTheme' can't be assigned to the parameter type 'BottomAppBarThemeData?'.
- - 'BottomAppBarTheme' is from 'package:flutter/src/material/bottom_app_bar_theme.dart' ('/usr/local/flutter/packages/flutter/lib/src/material/bottom_app_bar_theme.dart').
- - 'BottomAppBarThemeData' is from 'package:flutter/src/material/bottom_app_bar_theme.dart' ('/usr/local/flutter/packages/flutter/lib/src/material/bottom_app_bar_theme.dart').

- - dialogTheme: DialogTheme(
- Target kernel_snapshot_program failed: Exception
- 25.90 Build process failed
Environment / version details:
- Flutter tool installed: nightly-2024-12-02 (Flutter 3.43.0-1.0.pre-204, channel master; Engine hash e31d899346f30e82cfb9442be5d6dd17c73a6854; Dart 3.12.0)
- The errors indicate API changes: code uses BottomAppBarTheme, CardTheme, DialogTheme widgets, while the expected types are BottomAppBarThemeData, CardThemeData, DialogThemeData. This is a Flutter API mismatch between code and the Flutter version in use.
- Pub-get note: “14 packages have newer versions incompatible with dependency constraints.” (context for dependencies, not the direct cause)
Missing packages/files:
- None explicitly referenced as missing.
Root cause (implication):
- Flutter API changes between the code (widget theme classes) and the current Flutter tool version require updating the code to use the corresponding “Data” classes (BottomAppBarThemeData, CardThemeData, DialogThemeData) or aligning Flutter version to match the codebase. Also consider dependency constraint updates given the pub-get note.FROM ubuntu:22.04

Summary of Docker build error
- Failing step
- Step 8: RUN flutter --version && flutter doctor -v || true && flutter config --enable-linux-desktop && flutter pub get
- Exact error messages (preserved)
- "Woah! You appear to be trying to run flutter as root.
We strongly recommend running the flutter tool without superuser privileges.
/"
- "fatal: detected dubious ownership in repository at '/opt/flutter'
To add an exception for this directory, call:
git config --global --add safe.directory /opt/flutter"
- "ERROR: process "/bin/sh -c flutter --version && flutter doctor -v || true && flutter config --enable-linux-desktop && flutter pub get" did not complete successfully: exit code: 128"
- Missing packages or files mentioned
- None explicitly listed as missing. The failure is due to repository ownership checks when running Flutter as root. The log suggests adding a Git safe.directory exception for /opt/flutter, not a missing package/file.
- Version mismatch or related info
- Flutter/Rust setup shown in prior steps indicates installing a nightly Rust toolchain:
- nightly-2024-12-02-x86_64-unknown-linux-gnu installed - rustc 1.85.0-nightly (5e1440ae5 2024-12-01)
- The Flutter step is being run as root, which Flutter flags as problematic (ownership/auth issues) rather than a direct version mismatch, but the root-cause message is ownership-based (dubious ownership) during Flutter usage.FROM ubuntu:22.04

Summary (under 1500 chars):
- Exact error message and exit code
- ERROR: process "/bin/sh -c flutter build linux --release" did not complete successfully: exit code: 1
- Flutter output around failure:
- Building Linux application...
- CMake is required for Linux development.
- It is likely available from your distribution (e.g.: apt install cmake), or can be downloaded from https://cmake.org/download/
- Failing command/step
- [10/14] RUN flutter build linux --release (Dockerfile:63)
- Missing packages or files mentioned
- CMake is required for Linux development (not installed)
- Flutter doctor output also notes additional missing items (not directly causing this failure): Android SDK, Chrome executable, clang, cmake for Linux desktop. The key blocker for this step is cmake.
- Version mismatch / related info
- Flutter 3.29.3 • channel stable • https://github.com/flutter/flutter.git
- Framework revision ea121f8859 (11 months ago) • 2025-04-11 19:10:07 +0000
- Engine revision cf56914b32
- Dart 3.7.2
- The run shows “Changed 91 dependencies!” and “41 packages have newer versions incompatible with dependency constraints.”
- Linux host: Ubuntu 22.04.5 LTS
Notes
- The root cause is missing CMake needed to build Linux desktop artifacts; installing cmake (and ensuring it’s in PATH) should address this step.FROM ubuntu:22.04

Concerns: No actual build step for the Flutter desktop app is performed (e.g., flutter build linux). The Dockerfile initializes Flutter and fetches dependencies but does not compile the app into artifacts., The final image relies on a pub get with '|| true', which may mask misconfigurations or missing pubspec.yaml in the workspace., Potentially unnecessary PATH entry for /home/builder/.cargo/bin (cargo may not be installed).

Concerns: The Flutter install command uses single quotes, preventing shell variable expansion for FLUTTER_VERSION; download URL becomes flutter_linux_${FLUTTER_VERSION}-stable.tar.xz and will fail., The COPY/build steps assume the app is named jasmine and outputs to build/linux/x64/release/bundle/jasmine; if the project uses a different app name, the cp step will fail., Rust nightly is installed but may be unnecessary for this app and adds extra download/size; consider removing if not needed.FROM ubuntu:jammy-20260217

Exact error message and exit code
- Error: Unable to find git in your PATH.
- Exit code: 1
Context from the failing step
- After downloading and extracting Flutter, the command runs flutter --version and outputs root/run-as-root warnings before the fatal error:
- Woah! You appear to be trying to run flutter as root.
- We strongly recommend running the flutter tool without superuser privileges.
- /
- 📎
- Error: Unable to find git in your PATH.
Missing packages or files mentioned
- Git is not found in PATH (git binary missing or not installed in the image). Flutter requires git to be available in PATH during its checks.
Version/mismatch information
- Dockerfile ARG FLUTTER_VERSION=3.29.3
- Flutter tarball attempted: flutter_linux_${FLUTTER_VERSION}-stable.tar.xz (i.e., flutter_linux_3.29.3-stable.tar.xz)
- No explicit version mismatch reported; the failure is due to missing git in PATH rather than a Flutter version mismatch.FROM ubuntu:jammy-20260217

Build status: build_failed
Concerns
- Base image: ubuntu:jammy-20260217 may not be publicly available/reproducible; consider ubuntu:22.04 or pin a known stable base image.
- App/output path: assumes app named jasmine; final binary expected at build/linux/x64/release/bundle/jasmine; if project name changes, path breaks; parameterize app name or document expected output path.
- Context size: no .dockerignore shown; COPY . . copies entire repo; add .dockerignore to reduce build context and image size.
Build error
- Exit code: 128
- Failing output:
Woah! You appear to be trying to run flutter as root.
We strongly recommend running the flutter tool without superuser privileges.

fatal: detected dubious ownership in repository at '/opt/flutter'
To add an exception for this directory, call:
git config --global --add safe.directory /opt/flutter
- Failing command/step:
Step: #7 [3/22] RUN bash -lc "set -eux; mkdir -p /opt; curl -fL -o flutter.tar.xz https://storage.googleapis.com/flutter_infra_release/releases/stable/linux/flutter_linux_${FLUTTER_VERSION}-stable.tar.xz; tar -xJf flutter.tar.xz -C /opt; rm flutter.tar.xz; ln -s /opt/flutter/bin/flutter /usr/local/bin/flutter; flutter --version"
- The command downloads Flutter, extracts to /opt, symlinks, and runs flutter --version, which triggers the error.
Version info
- FLUTTER_VERSION: 3.29.3
- Flutter tarball: flutter_linux_3.29.3-stable.tar.xz (downloaded and extracted)
- The log indicates no version mismatch; the problem is ownership-related, not versioned incompatibility.
Root cause
- Running Flutter as root triggers "fatal: detected dubious ownership" for /opt/flutter.
Remediation (actionable)
- Run Flutter as a non-root user in the Docker build, or adjust ownership properly in the image.
- Alternatively, set a git safe.directory exception: git config --global --add safe.directory /opt/flutter (not ideal long-term).
- Consider updating the Dockerfile to create a non-root user with appropriate permissions and to avoid root-owned Dart/Flutter repos.FROM ubuntu:jammy-20260217

Summary of Docker build error (concise, actionable)
- Exact error message and exit code
fatal: detected dubious ownership in repository at '/opt/flutter'
To add an exception for this directory, call:
git config --global --add safe.directory /opt/flutter
Exit code: 128
- Failing command/step
RUN bash -lc "set -eux; mkdir -p /opt; curl -fL -o flutter.tar.xz https://storage.googleapis.com/flutter_infra_release/releases/stable/linux/flutter_linux_${FLUTTER_VERSION}-stable.tar.xz; tar -xJf flutter.tar.xz -C /opt; rm flutter.tar.xz; ln -s /opt/flutter/bin/flutter /usr/local/bin/flutter; flutter --version"
- Missing packages or files
None explicitly reported as missing. The failure is due to Git safety ownership check on /opt/flutter after extracting Flutter.
- Version mismatch information
- FLUTTER_VERSION in Dockerfile: 3.29.3 (stable)
- Flutter tarball attempted: flutter_linux_3.29.3-stable.tar.xz
No explicit version-mismatch error; the issue stems from repository ownership safety check.
- Related notes
- The log shows a preceding Flutter run-as-root warning, which is not the cause of the failure:

Concerns: Default CMD references /workspace/app/jasmine instead of the runtime binary at /app/jasmine; this will fail at container startup., The build copies the binary to /app/jasmine but the CMD uses /workspace/app/jasmine, indicating a path inconsistency that will break execution., Path decisions during build (COPY . . into /workspace, then /app for the runtime) are fragile; ensure the runtime path is consistent and documented.

Concerns: Missing build-essential in apt-get install; cargo build may require a C/C++ compiler and make for native crates, which will likely fail without the build tools., Potentially brittle base image tag: FROM ubuntu:jammy-20260217 may not align with security updates or reproducibility unless the exact tag is maintained; consider pinning to a more stable or updated base image., OUTPUT PATH ASSUMPTION: The build assumes the Flutter/Linux desktop output is at build/linux/x64/release/bundle/jasmine; if the project changes, this path may break and /app/jasmine may not be produced.

Docker build failed: process "/bin/sh -c ..." did not complete successfully: exit code: 2
- Failing command/step description:
The RUN command that downloads the Flutter tarball (flutter_linux_${FLUTTER_VERSION}-stable.tar.xz) and extracts it with tar -xJf, then runs flutter --version.
- Missing packages or files mentioned:
- The error indicates xz cannot be executed (xz is provided by the xz-utils package). This implies xz-utils is not installed in the image.
- Flutter tarball URL shown uses Flutter version 3.29.3-stable (the log shows flutter_linux_3.29.3-stable.tar.xz being downloaded).
- Version mismatch / info:
- Flutter version in use: 3.29.3-stable (flutter_linux_3.29.3-stable.tar.xz).
- Base image appears to be Ubuntu 22.04 (jammy) as context for this build step.FROM ubuntu:22.04

Summary (under 1500 chars)
- Failing step/command:
- Step: [12/15] RUN xvfb-run -a flutter build linux --release
- Exact error message and exit code:
- Exit code: 1
- Errors reported:
- Could not find compiler set in environment variable CXX:
clang++.
- CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
- Unable to generate build files
- Missing packages or files mentioned:
- The error indicates a missing C++ compiler: environment variable CXX is not set and clang++ cannot be found. In other words, a C++ compiler (e.g., clang++ or g++) is not available in the environment.
- Version mismatch / version info:
- Flutter and tooling versions shown during step 12/15:
- Flutter 3.29.3 • channel stable
- Dart 3.7.2
- During Flutter pub get (step 10/15):
- Output includes: Changed 91 dependencies!
- 41 packages have newer versions incompatible with dependency constraints.
- Suggestion: run flutter pub outdated for details.
Notes:
- The root cause appears to be the absence of a C++ compiler in the build image when running flutter build linux. Installing a C/C++ toolchain (e.g., build-essential, clang, or g++) should resolve the CXX not set error.FROM ubuntu:22.04

Summary of Docker build error
- Exact error messages and exit code
- tar (child): xz: Cannot exec: No such file or directory
- tar (child): Error is not recoverable: exiting now
- tar: Child returned status 2
- tar: Error is not recoverable: exiting now
- Exit code reported for the failing command: 2
- Failing command/step
- [ 8/15] RUN bash -lc "set -e; curl -fL -o flutter.tar.xz https://storage.googleapis.com/flutter_infra_release/releases/stable/linux/flutter_linux_${FLUTTER_VERSION}-stable.tar.xz; tar -xJf flutter.tar.xz -C /home/appuser/flutter --strip-components=1; rm flutter.tar.xz; flutter --version"
- The log shows the actual URL flutter_linux_3.29.3-stable.tar.xz and extraction attempt using tar -xJf.
- Missing packages or files mentioned
- Missing: xz (xz-utils) is not installed, causing tar to fail when extracting .tar.xz archives.
- Fix: install xz-utils (e.g., apt-get install -y xz-utils) in the image before extracting flutter.tar.xz.
- Version mismatch info
- Flutter download URL indicates version 3.29.3-stable (flutter_linux_3.29.3-stable.tar.xz) as seen in the log.
- No explicit version mismatch error reported; the failure is due to the missing xz tool.
