Worked on stabilizing the test infrastructure for the newrelic/open-install-library repository by updating the continuous integration environment from Debian 10 to Debian 11. This change addressed compatibility issues caused by the end-of-life status of Debian 10, ensuring that the test suite remains aligned with current operating system standards. The update reduced environment-related test flakiness and streamlined ongoing maintenance for downstream users. Leveraged DevOps practices and Infrastructure as Code principles, utilizing JSON to manage configuration changes. The work focused on maintaining readiness for future platform updates and keeping the CI/test matrix in sync with supported distributions, enhancing overall reliability and maintainability.
