This paper delves into common issues in Git's detached HEAD state, particularly the "fatal: You are not currently on a branch" error when users attempt to push modifications to a remote branch. It thoroughly analyzes the causes, including detached states from redeveloping from historical commits and non-fast-forward conflicts during pushes. Based on best practices, two main solutions are provided: a quick fix using force push (git push --force) and a safer strategy via creating a temporary branch and merging. The paper also emphasizes preventive measures to avoid detached HEAD states, such as using interactive rebase (git rebase -i) or branch revert. Through code examples and step-by-step explanations, it helps developers understand core concepts of Git branch management, ensuring stability and collaboration efficiency in version control workflows.
