Error: failed to push some refs to – How to Fix in Git
Ihechikara Vincent Abba
When collaborating with other developers using Git, you might encounter the error: failed to push some refs to [remote repo] error.
This error mainly occurs when you attempt to push your local changes to GitHub while the local repository (repo) has not yet been updated with any changes made in the remote repo.
So Git is trying to tell you to update the local repo with the current changes in the remote before pushing your own changes. This is necessary so that you don’t override the changes made by others.
We’ll be discussing two possible ways of fixing this error in the sections that follow.
How to Fix the error: failed to push some refs to Error in Git
We can fix the error: failed to push some refs to [remote repo] error in Git using the git pull origin [branch] or git pull —rebase origin [branch] commands. In most cases, the latter fixes the error.
Let’s go over how you can use the commands above.
How to Fix error: failed to push some refs to Error in Git Using git pull
To send a pull request means to «fetch» new changes made to the remote repo and merge them with the local repo.
Once the merging is done, you can then push your own code changes to GitHub.
In our case, we’re trying to get rid of the error: failed to push some refs to [remote repo] error by sending a pull request.
Here’s how you can do that:
If you’re working with a different branch, then you’d have to replace main in the example above with the name of your branch.
Just keep in mind that there are chances of failure when using this command to sync your remote and local repos to get rid of the error. If the request succeeds, then go on and run the command below to push your own changes:
If the error persists, you’ll get an error that says: fatal: refusing to merge unrelated histories . In that case, use the solution in the next section.
How to Fix error: failed to push some refs to Error in Git Using git pull —rebase
The git pull —rebase command is helpful in situations where your local branch is a commit behind the remote branch.
To fix the error, go on and run following commands:
If the first command above runs successfully, you should get a response that says: Successfully rebased and updated refs/heads/main .
The second command pushes your local repo’s current state to the remote branch.
Summary
In this article, we talked about the error: failed to push some refs to [remote repo] error.
This error occurs when you attempt to push your local changes to the remote repo without updating your local repo with new changes made to the remote repo.
We discussed two commands that you can use to fix the error: the git pull origin [branch] and git pull —rebase origin [branch] commands.
Что за ошибка при push в Git?
Здравствуйте! Изучаю Git, при пуше на сервер вылазит вот такая ошибка, что это значит?
Мои действия:
1. Форкнул проект
2. Создал на компе папку, написал git init
3. git clone .
4. git status
5. git add .
6. git status
7. git commit -m «text»
8. git push -u name-repo master
Правильно ли я вообще делаю?

git init не нужен, если потом используется git clone .
Ошибка из-за того, что на сервере есть изменения, которых у Вас нет в локальном хранилище.
Нужно сделать git pull перед git push .
Dealing with non-fast-forward errors
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:
You can fix this by fetching and merging the changes made on the remote branch with the changes that you have made locally:
Or, you can simply use git pull to perform both commands at once:

How to Fix ‘failed to push some refs to’ Git Errors
failed to push some refs to is a Git error that many developers frequently face. It occurs when a developer attempts to push committed code to an external git repository. The ability to push code stopped working suddenly, despite it working yesterday or the day before. It can be a source of frustration and annoyance for many.
failed to push some refs to errors are often caused when changes are not committed before pushing, issues with Git pre-push hook, incorrect branch name, or the local repository not being in sync with the Git repository. It occurs most of the time because multiple contributors are working on the same branch and the remote repository is further along than what you currently have on your local machine.
It is easy for git pushes to overlap when working in teams or for ref heads to be in different positions. This overlap can cause the repository to be out of sync, which is why the failed to push some refs to error are so frequent.
What causes ‘failed to push some refs to’ error
When multiple developers work on the same branch, it can cause a sequencing issue in Git. A commit gets rejected and causes a failed to push some refs to error because the remote branch contains code that you do not have locally. What this means is that your local git repository is not compatible with the remote origin.
Here is an abstraction of what incompatibility looks like in Git:
Based on the above, your local machine is missing commits C and D. Meanwhile, you are trying to slot in your commit – E – between B and C on the remote.
Before Git lets you proceed, you will need to integrate the remote changes into your local repository. This step will fix any incompatibility issues and ensure that your version is up to date with the remote.
How can you fix ‘failed to push some refs to’ errors
Here are the scenarios that may cause the failed to push some refs error, and how to correct them:
1.Another developer pushed a commit to the same branch
The error in your terminal looks like this:
When this occurs, the head sits at different positions on the same code timeline, and Git does not know how to handle it. This is because the origin repository is ahead of where you currently are. To fix this issue, run git pull on your local repository. This should allow you to push to origin again.
2. You got a ‘master (non-fast-forward)’ error with a ‘failed to push some refs to’ error
A git fast-forward happens when the ref pointer gets moved forward in the commit history. However, if your code diverges before it reaches the latest commit, it can cause the non-fast-forward issue and lead to a failed to push some refs to error.
To solve this issue, you can pull with the —rebase flag. —rebase will let you move your intended files to commit over to the latest pull code.
Here is how to pull with —rebase :
3. You got a ‘master (fetch first)’ error with a ‘failed to push some refs to’ error
When this occurs, someone has pushed to the branch before you. Git wants you to pull first before you can push your committed changes.
To prevent the loss of your work during the pull , you can stash your local changes.
The common suggested fix is to use —force flag to push through the local changes. However, it is good practice to avoid using the —force flag as it can cause inconsistency issues. Instead, use —rebase to move the ref heads and update your local repository without causing a divergence in the remote repository.
Using —force to try and fix the failed to push some refs to error will only result in more errors in the long run. This occurs because —force uses a brute force method that puts your current code and its ref head as the source of truth.
As a result, the changes in the remote can be overwritten by what you have pushed, removing any features or updates that other developers may have committed.
Only use —force if you are comfortable with features not on your local being overwritten with what you’ve currently got. Use the —force flag if you are confident that your local repository in its current state is correct.
How to prevent ‘failed to push some refs to’ errors
To prevent failed to push some refs to errors in Git, it is good practice to avoid having multiple developers work on the same branch simultaneously. Instead, use feature branches that merge into a master branch or something equivalent.
If you get a failed to push some refs to error, the main thing to do is git pull to bring your local repo up to date with the remote. Avoid employing the —force flag when using git pull and prevent other developers’ accidental overwrites of committed features.
Use the —rebase flag instead to avoid other errors from occurring while fixing your original failed to push some refs to error.
