Episode 7 — Distros and packages: RPM-based vs dpkg-based thinking
Linux+ tests distribution awareness because real environments are mixed, and exam questions may describe commands, file locations, or package behaviors without naming the distro explicitly. This episode builds a clean mental model for RPM-based versus dpkg-based ecosystems as two families with similar outcomes: install software, manage dependencies, verify integrity, and keep systems patchable. You’ll focus on the “thinking layer” instead of command memorization: how packages are named, how dependencies are resolved, how repositories are enabled, and how you confirm what’s installed. Understanding these differences helps you interpret questions that hinge on whether a system uses rpm/yum/dnf style tooling or dpkg/apt style tooling, and it prevents you from applying the right idea with the wrong mechanism.
Next, we expand into operational scenarios where package-family differences change troubleshooting. You’ll learn how to diagnose “package not found,” “dependency conflict,” and “held back” update behaviors by separating repository reachability from trust and metadata issues. We also cover verification habits that matter on the exam: confirming the owning package for a file, checking package versions, and validating whether a change came from a repo update versus a local manual install. Finally, we reinforce safe rollback thinking: what can be reversed cleanly, what leaves residue in config and state directories, and why documenting package changes is a reliability practice, not bureaucracy. The outcome is confidence switching between families without guessing, even when the question wording is intentionally minimal.
