Nonfastforward, often written as non-fast-forward, is a term used in Git and other distributed version control systems to describe a branch update that cannot be performed by a simple forward move of the branch pointer. In Git this occurs when the history of the remote branch has diverged from the local history, so there is no fast-forward path from the remote tip to the new commit.
In practical terms, a non-fast-forward situation arises most commonly during pushes. If the remote repository contains
Common causes include collaborative workflows where multiple people push to the same branch, rebasing local commits,
Ways to resolve a nonfastforward situation:

- Rebase your local commits on top of the updated remote: git fetch origin; git rebase origin/branch,
- If you intentionally want to overwrite the remote (use with caution): git push --force-with-lease to prevent
Nonfastforward is a normal condition in collaborative workflows and is not a bug; it signals that history
