This article provides a comprehensive analysis of the common Git push permission error 'unpacker error', typically manifested as 'insufficient permission for adding an object to repository database'. It first examines the root cause—file system permission issues, particularly write permission conflicts in object directories within multi-user environments. The article systematically presents three solution approaches: repair using git fsck and prune, automatic permission adjustment via post-receive hooks, and user group permission management. It details the best practice solution—repairing corrupted object databases using Git's internal toolchain, validated effective on both Windows and Linux systems. Finally, it compares the advantages and disadvantages of different approaches and provides preventive configuration recommendations to help developers establish stable collaborative workflows.

This technical article examines the crucial distinction between two common parameter forms in Git's rebase command: git rebase origin/branch versus git rebase origin branch. Drawing from official documentation and practical scenarios, it explains how the former rebases the current branch onto a remote branch, while the latter rebases a specified branch onto a remote repository. The analysis covers parameter semantics, default behaviors, and provides workflow recommendations to prevent conflicts, offering developers clear guidance for proper Git operation usage.
