Concerns: FROM instruction has invalid syntax: there is a space after the colon in 'ubuntu: jammy-20260217'. It should be 'ubuntu:jammy-20260217'. This will cause a build error., The same syntax issue appears in the second FROM line (runtime stage): 'FROM ubuntu: jammy-20260217 as runtime'. It should be 'FROM ubuntu:jammy-20260217 AS runtime'.

VerifyBuildbuild_failed

- Status: VerifyBuild status: build_failed

- Key issue: SSL certificate verification failure during Git clone of ruapu.git via HTTPS in FetchContent. CAfile: none CRLfile: none (appeared multiple times)

- Failing step:
  - builder 5/6: RUN cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DAC_BUILD_GUI=OFF -DAC_BUILD_VIDEO=OFF -DAC_BUILD_BINDING_C=OFF -DAC_BUILD_BINDING_PYTHON=OFF -DAC_BUILD_CLI=ON

- Exact error messages:
  - fatal: unable to access 'https://github.com/nihui/ruapu.git/': server certificate verification failed. CAfile: none CRLfile: none
  - Build step for ruapu failed: 2
  - CMake Error at ruapu-subbuild/ruapu-populate-prefix/tmp/ruapu-populate-gitclone.cmake:31 (message): Failed to clone repository: 'https://github.com/nihui/ruapu.git'
  - CMake Error at /usr/share/cmake-3.22/Modules/FetchContent.cmake:1087 (message): Build step for ruapu failed: 2
  - Configuring incomplete, errors occurred!
  - The overall Docker build reported: failed to solve: process "/bin/sh -c cmake ..." did not complete successfully: exit code: 1

- Missing files/packages: None reported locally missing; issue is SSL/TLS verification during remote fetch

- Version info / mismatches:
  - The CXX compiler identified as GNU 11.4.0 during the cmake configure step
  - Clone failure is independent of compiler versions; SSL certificate verification (CAfile: none CRLfile: none)

- Context: Occurs while FetchContent tries to populate ruapu via HTTPS, causing cmake configure to fail and abort the build

- Quick fixes (actionable):
  - Ensure the image/host has a valid CA certificate store (install/update ca-certificates)
  - Consider alternative fetch: use SSH URL with proper keys or a trusted TLS setup
  - Avoid disabling certificate verification (not recommended)
  - Optional: add .dockerignore to reduce build context and avoid shipping unnecessary files

- References (paths/URLs):
  - https://github.com/nihui/ruapu.git
  - ruapu-subbuild/ruapu-populate-prefix/tmp/ruapu-populate-gitclone.cmake
  - /usr/share/cmake-3.22/Modules/FetchContent.cmake
  - The failing command: cmake (as invoked in the RUN step)

Concerns: Runtime image may miss some runtime dependencies (e.g., libgcc1) required by the dynamically linked ac_cli; consider installing libgcc1 (and potentially others) in the runtime stage., Using a specific base tag (ubuntu:jammy-20260217) is valid if it exists, but a more general tag like ubuntu:22.04 or a digest would be more reproducible.
