Rejected Non Fast Forward-Git Push Rejected “Non-Fast-Forward”

1.5K Asked by Ankesh Kumar in Devops , Asked on Nov 16, 2022

I am fairly new to git yet currently using it to manage our code in a team environment. I had some rebasing issues and I fixed them using

git checkout --ours filename.txt

git add filename.txt

git rebase --continue

Now I wish to push my changes, and so running the following command

$ git push origin feature/my_feature_branch

gives me the following error:

To ssh://git@coderepo.com:7999/repo/myproject.git

! [rejected] feature/my_feature_branch -> feature/my_feature_branch (non-fast-forward)

error: failed to push some refs to 'ssh://git@coderepo.com:7999/repo/myproject.git'

hint: Updates were rejected because the tip of your current branch is behind

hint: its remote counterpart. Merge the remote changes (e.g. 'git pull')

hint: before pushing again.

hint: See the 'Note about fast-forwards' in 'git push --help' for details.

What can I do to get rid of the error? What does git push rejected non-fast-forward mean?

I found some useful instructions in the github help page and wanted to share them here. Sometimes, Git can't make your change to a remote repository without losing commits. When this happens, your push is refused. If another person has pushed to the same branch as you, Git won't be able to push your changes:

$ git push origin master

To https://github.com/USERNAME/REPOSITORY.git

 ! [rejected]        master -> master (non-fast-forward)

error: failed to push some refs to 'https://github.com/USERNAME/REPOSITORY.git'

To prevent you from losing history, rejected Master master non-fast-forward updates were rejected

Merge the remote changes (e.g. 'git pull') before pushing again.  See the

'Note about fast-forwards' section of 'git push --help' for details.

You can fix this by fetching and merging the changes made on the remote branch with the changes that you have made locally:

$ git fetch origin

# Fetches updates made to an online repository

$ git merge origin YOUR_BRANCH_NAME

# Merges updates made online with your local work

Or, you can simply use git pull to perform both commands at once:

$ git pull origin YOUR_BRANCH_NAME

# Grabs online updates and merges them with your local work.
