- VerifyBuild status: build_failed
- Concerns
- Base image node:12-slim is end-of-life; upgrade to a supported LTS (e.g., node:18-alpine or node:20-slim).
- No non-root user defined; container runs as root by default (security concern for production).
- If this is a GUI/desktop app (Electron), headless/container setup may be required (DISPLAY, X11/VNC, or headless Electron). Current CMD is just bash for inspection.
- Build error
- Failing step: [2/7] RUN apt-get update && apt-get install -y --no-install-recommends git ca-certificates python3 build-essential && rm -rf /var/lib/apt/lists/*
- Exact error (exit code 100):
ERROR: failed to build: failed to solve: process "/bin/sh -c apt-get update && apt-get install -y --no-install-recommends git ca-certificates python3 build-essential && rm -rf /var/lib/apt/lists/*" did not complete successfully: exit code: 100
- Missing packages/files due to deprecated Debian stretch repositories:
- 404 Not Found for http://deb.debian.org/debian/dists/stretch/main/binary-amd64/Packages
- 404 Not Found for http://deb.debian.org/debian/dists/stretch-updates/main/binary-amd64/Packages
- 404 Not Found for http://security.debian.org/debian-security/dists/stretch/updates/main/binary-amd64/Packages
- The repository 'http://deb.debian.org/debian stretch Release' does not have a Release file.
- Result: E: Some index files failed to download. They have been ignored, or old ones used instead.
- Consequence: The requested packages (git, ca-certificates, python3, build-essential) could not be retrieved/installed.
- Version mismatch / context
- Base image node:12-slim uses Debian Stretch; Stretch repositories are end-of-life and no longer provide Release files, causing apt-get update/install to fail. This mismatch leads to the 404/Release-file errors.FROM node:14-slim

- Err:6 http://deb.debian.org/debian buster-updates Release
404 Not Found [IP: 151.101.22.132 80]
- The following apt errors indicate the repositories do not have a Release file:
- E: The repository 'http://deb.debian.org/debian buster Release' does not have a Release file.
- E: The repository 'http://deb.debian.org/debian-security buster/updates Release' does not have a Release file.
- E: The repository 'http://deb.debian.org/debian buster-updates Release' does not have a Release file.
- Version mismatch info:
- The base image in use is node:14-slim (as seen in the build steps), which is pulling Debian "buster" (Debian 10) repositories. Those Debian buster repos are end-of-life and no longer provide Release files, causing the apt-get update to fail with 404 and “Release file” errors. This indicates a version mismatch between the base image (Debian buster) and the current apt repositories.FROM node:12-slim WORKDIR /app # Install dependencies from lockfile for reproducible builds COPY package.json package-lock.json ./ RUN npm ci # Copy the rest of the source and build COPY . .

Concerns: Node version is based on node:12-slim which is end-of-life; consider upgrading to a current LTS image (e.g., node:18-slim) for security and compatibility.
