Original Pull Request: https://github.com/bigbeartechworld/big-bear-scripts/pull/59

State: closed
Merged: Yes

This pull request significantly improves the robustness and reliability of the Docker downgrade and compatibility script for CasaOS, particularly in complex environments where multiple Docker installations or conflicting binaries may exist. The changes enhance conflict detection, verification, and troubleshooting, making the script more user-friendly and resilient to edge cases.

Key improvements include:

Conflict Detection and Pre-Checks

Added functions to detect and remove Docker installations via Snap, which can conflict with apt-based Docker, and to check for multiple Docker binaries in the system path, warning the user if conflicts are detected. [1] [2] [3]

Verification and Diagnostics

Implemented functions to verify the version of the dockerd binary and the Docker API version both before and after changes, ensuring the correct versions are in use and providing clear feedback if expectations are not met. [1] [2] [3] [4] [5] [6]
Expanded the script's output with detailed diagnostics and troubleshooting steps when the Docker API version does not change as expected, helping users resolve common issues. [1] [2]

Process and Service Management

Improved shutdown and cleanup logic by ensuring all Docker and containerd-related processes are fully terminated before proceeding with installation or upgrades, reducing the risk of version conflicts or failed downgrades. [1] [2] [3]

Documentation and Testing

Updated the README.md to document new checks, verification steps, and troubleshooting advice, and added instructions for a new test script to validate the fix in various scenarios. [1] [2] [3]

User Experience

Enhanced script messaging and step-by-step output to make the process clearer and more transparent for users, including explicit reporting of version changes and next steps if issues are detected. [1] [2] [3]

These changes collectively make the script safer and more effective for users running CasaOS in environments where Docker version mismatches or installation conflicts are likely.
