How to Fix "Warning: Symbolic Ref Is Dangling" In Git?

8 minutes read

When you encounter the warning "symbolic ref is dangling" in git, it means that a symbolic reference (symbolic ref) points to a commit that no longer exists in the repository. This can happen when branches or tags are force deleted, rewound, or otherwise modified in a way that invalidates the reference.


To fix this warning, you can update the symbolic reference to point to a valid commit hash or update the reference to point to a different branch or tag. This can be done using the git update-ref command or by manually editing the git configuration files.


Alternatively, you can remove the symbolic reference entirely if it is no longer needed by using the git symbolic-ref command or manually editing the git configuration files.


It is important to address dangling symbolic references in git to avoid potential inconsistencies or errors in your repository. Regularly checking and updating symbolic references can help maintain the integrity of your git history and ensure smooth operations when working with branches and tags.
