The Short Answer

To fix the “Push Rejected” error in GitHub, advanced users can use the command git push -f to force push their changes, but be cautious as this can overwrite existing commits. Alternatively, use git push --force-with-lease to safely force push while avoiding overwriting other users’ changes.

Why This Error Happens

• Reason 1: The most common cause of the “Push Rejected” error is when the remote repository has been updated since the last time you pulled, and your local branch is not up-to-date. This can happen when multiple users are collaborating on the same repository and one user pushes changes before you do.
• Reason 2: An edge case cause of this error is when the Git configuration option receive.denyCurrentBranch is set to updateInstead on the remote repository, which prevents pushing to the current branch if it’s not a fast-forward update.
• Impact: The “Push Rejected” error results in a Git error, preventing you from pushing your changes to the remote repository, which can hinder collaboration and version control.

Step-by-Step Solutions

Method 1: The Quick Fix

1. Go to Repository Settings > Branches > Branch permissions
2. Toggle Update permissions to allow force pushes or set the default branch to a different branch that allows force pushes.
3. Refresh the page and try pushing again.

Method 2: The Command Line/Advanced Fix

Use the command git push origin <branch-name> --force-with-lease to force push your changes while ensuring you don’t overwrite other users’ changes. This method is safer than a simple git push -f as it checks if the remote branch has been updated before forcing the push.

Prevention: How to Stop This Coming Back

• Best practice configuration: Regularly pull from the remote repository before pushing your changes to ensure your local branch is up-to-date.
• Monitoring tips: Use Git hooks or GitHub webhooks to notify team members when someone pushes changes to the repository, helping you stay aware of updates and avoid push rejections.

If You Can’t Fix It…

[!WARNING] If GitHub keeps crashing or you’re experiencing persistent issues with force pushes, consider switching to GitLab which handles force push fixes natively without these errors, offering more robust version control features.

FAQ

Q: Will I lose data fixing this? A: Using git push -f can potentially overwrite existing commits, resulting in data loss. However, using git push --force-with-lease minimizes this risk by checking for updates before forcing the push.

Q: Is this a bug in GitHub? A: The “Push Rejected” error is not a bug in GitHub but rather a safety feature to prevent accidental overwriting of commits. This behavior has been present in Git since version 1.6.0, and GitHub’s implementation follows standard Git protocols.

The Short Answer

To fix the “Push Rejected” error in GitHub, use the command git push -f with caution, as it will overwrite the remote repository. Alternatively, resolve the conflict by pulling the latest changes, merging them with your local code, and then pushing again.

Why This Error Happens

• Reason 1: The most common cause of the “Push Rejected” error is when the remote repository has been updated since your last pull, and your local branch is not up-to-date. This can happen when multiple developers are working on the same project, and one of them pushes changes to the remote repository before you do.
• Reason 2: An edge case cause of this error is when the Git configuration option receive.denyCurrentBranch is set to updateInstead on the remote repository, and you’re trying to push to a non-bare repository. This option is typically used on shared repositories to prevent accidental overwrites.
• Impact: The “Push Rejected” error can significantly impact code deployment, as it prevents you from updating the remote repository with your latest changes. This can lead to delays in releasing new features or fixing critical bugs, ultimately affecting your users and customers.

Step-by-Step Solutions

Method 1: The Quick Fix

1. Go to Settings > Branches > Branch permissions
2. Toggle Require pull request reviews before merging to Off
3. Refresh the page to ensure the changes take effect.

Method 2: The Command Line/Advanced Fix

Use the following Git command to force push your changes: git push origin <branch-name> -f. However, be cautious when using this command, as it will overwrite the remote repository. To avoid conflicts, make sure to pull the latest changes, merge them with your local code, and then push again:

1
2
3

git pull origin <branch-name>
git merge origin/<branch-name>
git push origin <branch-name>

Alternatively, you can use git push origin <branch-name> --force-with-lease to force push your changes while still checking if the remote repository has been updated.

Prevention: How to Stop This Coming Back

To prevent the “Push Rejected” error from happening in the future, configure your Git repository to use a pull request workflow. This involves creating a new branch for each feature or bug fix, submitting a pull request, and then merging the changes into the main branch. Additionally, make sure to:

• Regularly pull the latest changes from the remote repository
• Use git status and git diff to check for any conflicts before pushing your changes
• Set up Git hooks to enforce coding standards and prevent accidental pushes

If You Can’t Fix It…

FAQ

Q: Will I lose data fixing this? A: The risk of data loss depends on the method you choose to fix the “Push Rejected” error. Using git push -f can overwrite the remote repository, potentially leading to data loss. However, if you follow the step-by-step solutions outlined above, you can minimize the risk of data loss.

Q: Is this a bug in GitHub? A: The “Push Rejected” error is not a bug in GitHub, but rather a safety feature designed to prevent accidental overwrites of the remote repository. This feature has been present in Git since version 1.6.0, and GitHub has implemented it to ensure the integrity of your code repositories.
