Root Cause

apt package cache stale in Docker build. Common with cached layers.

generic

Workarounds

  1. 95% success Always run apt-get update && apt-get install in same RUN layer 
    RUN apt-get update && apt-get install -y pkg && rm -rf /var/lib/apt/lists/*

    Sources: https://docs.docker.com/build/building/best-practices/#apt-get

  2. 85% success Use specific base image tags, not :latest 
    # Use specific version tags:
FROM ubuntu:22.04  # Not FROM ubuntu:latest
FROM python:3.12-slim  # Not FROM python:latest
FROM node:20-alpine  # Not FROM node:latest

Dead Ends

Common approaches that don't work:

  1. Pin specific mirror URL 60% fail

    Mirrors change too; doesn't fix stale cache layer

  2. Use --no-cache for entire build 50% fail

    Rebuilds everything, very slow
