The main objective was to complete the lab workflow end to end and validate the core concepts, tooling, and verification steps in a realistic Ubuntu 24.04 cloud environment.
This lab developed hands-on skills such as define and implement dependency upgrade policies, test dependency changes safely before production deployment, identify and mitigate dependency-related risks, automate dependency security scanning.
The workflow was broken into staged tasks that covered setup, implementation, validation, and post-task verification. Key phases included Define Upgrade Policies; Test Dependency Changes.
Pinned versions reduced drift and made it easier to detect unexpected changes during controlled upgrade testing.
Using both tools improved visibility into dependency risk and supported policy-driven security review before upgrades.
The upgrade changed the installed version while the pinned requirement still expected the previous version, so the version policy test correctly failed and triggered rollback logic.
The comparison highlighted that different ecosystems surface upgrade and security risk differently, which helps build broader package-management awareness.
It automated outdated-package inspection, policy classification, branch creation, testing, and report generation for safer upgrades.
An important validation step was confirming that the implementation behaved as expected after setup, testing, and verification checks were completed.
