Mar 1, 2025March 2025 monthly summary: Focused on stability and automation for Debian-based upgrade workflows within the microsoft/lisa repository. Implemented a synchronization mechanism to wait for the package manager to be idle before performing upgrades, preventing conflicts and reducing upgrade failures. This change introduces a wait-for-lock behavior in the UpgradeInstaller, improving reliability in concurrent upgrade scenarios (Commit 1e2cd159b160036101b7b953479be0b917b8cfc9). Result: more dependable upgrade processes, smoother CI runs, and lower support impact.
