- Add comprehensive debug output to trace Docker installation execution paths
- Fix early return issue that was skipping Linux Mint repository fix
- Reorder Docker removal to clean repositories before running apt commands
- Add specific cleanup for Linux Mint codenames (xia, vera, vanessa)
- Prevent apt errors during existing Docker removal process
