Summary of Docker build error

- Failing step
  - [2/6] RUN set -eux; apt-get update && apt-get install -y --no-install-recommends openjdk-8-jdk bash curl unzip ca-certificates && rm -rf /var/lib/apt/lists/*; mkdir -p /usr/local/bin; curl -L -o /usr/local/bin/bazelisk https://github.com/bazelbuild/bazelisk/releases/latest/download/bazelisk-linux-amd64; chmod +x /usr/local/bin/bazelisk; ln -s /usr/local/bin/bazelisk /usr/local/bin/bazel

- Exact error messages
  - E: Unable to locate package openjdk-8-jdk
  - /bin/sh: 1: curl: not found

- Exit code
  - 127

- Missing packages/files mentioned
  - openjdk-8-jdk (not found in Debian bullseye-slim repos)
  - curl (not found after the install attempt; indicates curl wasn’t installed due to the prior failure)

- Version mismatch / root cause
  - Base image is Debian bullseye-slim; OpenJDK 8 is not available in bullseye repositories (package not found). This indicates a mismatch between requested OpenJDK 8 and the Debian version. Recommended to use a newer JDK (e.g., openjdk-11-jdk or openjdk-17-jdk) or switch base image to a Debian release that still provides OpenJDK 8, or install from an alternative repository.
