Troubleshooting Guide: Fixing Remote Rejected Master Errors and Pre-Receive Hook Declines

Remote Rejected Master errors and Pre-Receive Hook declines are common issues faced by developers when working with Git repositories. This guide will help you understand the causes behind these errors and provide step-by-step solutions to fix them.

Understanding Remote Rejected Master Errors

Remote Rejected Master errors occur when your local branch is out of sync with the remote branch, and you're trying to push changes. This usually happens when someone else has pushed changes to the remote branch, and you haven't updated your local branch yet.

Causes of Remote Rejected Master Errors

  1. A conflict between local and remote branches.
  2. The remote branch has been updated, and your local branch is behind.
  3. You're trying to push to a protected branch with force push.

Fixing Remote Rejected Master Errors

Step 1: Fetch the latest changes from the remote branch

git fetch origin

Step 2: Merge the remote branch with your local branch

git merge origin/master

Step 3: Resolve any merge conflicts

If there are any conflicts, Git will prompt you to resolve them. Open the files with conflicts and manually resolve them. Once you've resolved the conflicts, stage the changes by running:

git add <file_with_resolved_conflict>

Step 4: Commit the merge

git commit -m "Merged origin/master"

Step 5: Push the changes to the remote branch

git push origin master

Understanding Pre-Receive Hook Declines

Pre-receive hooks are server-side scripts that run whenever you push changes to a remote repository. These hooks are commonly used to enforce certain policies, such as preventing force pushes or ensuring that commit messages follow a specific format.

Causes of Pre-Receive Hook Declines

  1. The changes you're trying to push violate a policy enforced by the pre-receive hook.
  2. A bug or misconfiguration in the pre-receive hook script.

Fixing Pre-Receive Hook Declines

Step 1: Identify the cause of the decline

Read the error message associated with the pre-receive hook decline. It should provide information about the specific policy you're violating or the issue with the script.

Step 2: Address the issue

Depending on the cause, you may need to:

  • Update your commit message to follow the required format.
  • Split your commits into smaller, more focused changes.
  • Consult your team or repository administrator to fix the pre-receive hook script or update its configuration.

Step 3: Push the changes again

Once you've addressed the issue, try pushing the changes again:

git push origin master


How do I update my local branch without merging?

You can use git rebase instead of git merge to update your local branch without creating a merge commit:

git fetch origin
git rebase origin/master

What is a force push, and when should I use it?

A force push is a Git command that forcefully overwrites the remote branch with your local branch, regardless of any conflicts. It's generally not recommended to use force push, as it can lead to data loss and issues in the repository's history. Use force push only when you're sure that the changes you're pushing are correct and won't cause issues for other collaborators.

How do I create a custom pre-receive hook?

To create a custom pre-receive hook, you'll need to write a script (typically in Bash or Python) that enforces the policies you want to implement. Then, add the script to the ".git/hooks" directory in your remote repository. Consult the Git documentation for more information on creating and configuring pre-receive hooks.

How do I disable a pre-receive hook?

To disable a pre-receive hook, you can either delete the hook script from the ".git/hooks" directory or rename it so that it doesn't have the "pre-receive" prefix. Note that disabling a pre-receive hook may impact the repository's policies and should be done with caution.

Can I bypass a pre-receive hook decline?

Bypassing a pre-receive hook decline is generally not recommended, as it might violate your repository's policies. If you believe the decline is due to a bug or misconfiguration, consult your team or repository administrator for assistance.
