GitHub is a widely used platform for hosting and collaborating on software development projects. One common scenario is when you want to contribute to an open-source project that is hosted on GitHub, but you don’t have write access to the original repository. In such cases, you can fork the repository, make your changes in the forked repository, and then submit a pull request to the original repository. However, what happens when the original repository is updated and you want to sync your forked repository with those changes? This article will guide you through the process of updating the forked repo in GitHub.
Before we dive into the steps, it’s important to understand the concept of a forked repository. When you fork a repository, you create a copy of the original repository under your account. This copy is completely separate from the original repository and allows you to freely make changes without affecting the original project. However, it also means that your forked repository is not automatically updated when changes are made to the original repository. You need to manually sync your forked repo with the updates.
The first step is to navigate to your forked repository in GitHub. Once you are in your repository, click on the “Pull request” button located at the top of the page. This will take you to the “Pull request” page where you can see a list of all the pull requests you have made. At the top of the pull request page, you will see a branch selector. Make sure you have selected the branch that you want to update.
After selecting the branch, click on the “New pull request” button. GitHub will compare the changes between your forked repository and the original repository and prompt you to create a new pull request. At this point, you can review the changes and leave a comment if necessary. Once you are satisfied, click on the “Create pull request” button to submit the pull request. The owner of the original repository will then review your changes and decide whether to merge them into the main project.
Updating the Forked Repo: Why and When
When working with a forked repository on GitHub, it’s important to keep the forked repo up to date with the original repository. This ensures that you have the latest changes and fixes from the original repo and allows you to contribute changes back to the original repository if desired.
Why update the forked repo?
- Stay up to date with the latest changes: By updating the forked repo, you can easily access the latest features, bug fixes, and improvements made by the original repo maintainers.
- Collaborate and contribute: Updating the forked repo allows you to collaborate with the original repo maintainers and contribute your own changes, improvements, or bug fixes.
- Resolve conflicts: When making changes to a forked repo and then updating it with the changes from the original repo, conflicts may occur. Updating the forked repo regularly helps to identify and resolve these conflicts early on.
When to update the forked repo?
- Before starting to work on new changes: It is recommended to update the forked repo before starting to work on any new changes. This ensures that your local copy is up to date and prevents your changes from conflicting with any recent updates made to the original repo.
- When notified of changes in the original repo: If you receive notifications or updates from the original repo maintainers about new changes, it’s a good time to update your forked repo to incorporate those changes.
- Periodically: Even if you don’t receive any specific notifications, it’s a good practice to update your forked repo periodically, especially if you’re actively working on a project or collaborating with others.
By staying up to date with the latest changes in the original repository and regularly updating your forked repo, you can ensure that you are working with the most recent codebase and can seamlessly contribute back to the original repo when needed.
Why updating the forked repo in GitHub is important?
Updating the forked repository in GitHub is crucial for keeping your codebase up-to-date and ensuring that any improvements or bug fixes made to the original repository are reflected in your fork. By regularly updating your forked repo, you can benefit from new features, performance enhancements, and security patches implemented by the original repository.
Here are some key reasons why updating the forked repository is important:
1. Staying in sync with the original repository
When you fork a repository on GitHub, you create a separate copy of the original repository in your own GitHub account. However, the forked repository will not automatically sync with the changes made to the original repository. By updating the forked repo, you ensure that your code is up-to-date with the latest changes made by the original repository’s maintainers.
2. Incorporating bug fixes and improvements
By regularly updating your forked repository, you can incorporate bug fixes and improvements made by the original repository. This ensures that any known issues or vulnerabilities in your forked code are addressed, providing a more stable and secure codebase. It also allows you to take advantage of any new features or enhancements added to the original repository.
3. Contributing to the open-source community
If you have forked a repository as part of your contribution to an open-source project, updating your forked repo is essential for sending pull requests and contributing to the project. By keeping your forked repository up-to-date, you can easily merge your changes with the latest version of the original repository, ensuring a smooth integration process for your contributions.
Updating the forked repo in GitHub is a best practice for any developer who has created a forked repository. It allows you to benefit from the ongoing development and improvements made in the original repository, keeping your codebase aligned with the latest standards and ensuring a smooth collaboration process with the original repository’s maintainers. Therefore, it is highly recommended to regularly update your forked repo in GitHub.
When should you update your forked repo?
Updating your forked repository is an important step in the development process, especially if you plan to contribute back to the original repository or if the original repository has undergone significant changes. Here are some scenarios when you should consider updating your forked repo:
1. New updates or bug fixes in the original repository
If the original repository has released new updates or bug fixes, it is essential to update your forked repo to incorporate those changes. This ensures that your forked repo remains up-to-date and aligns with the latest developments in the project.
2. Collaborative development or pull request
If you are collaborating with other developers or have submitted a pull request to the original repository, updating your forked repo becomes necessary. This allows you to resolve any conflicts that may arise due to changes made by others and ensures that your contributions can be smoothly integrated into the project.
Updating your forked repository should be done regularly to minimize divergence from the original repository. By keeping your forked repo up-to-date, you can take advantage of the latest features, bug fixes, and improvements made by the community.
How to Sync the Forked Repo with the Original Repo
When you fork a repository on GitHub, you create a copy of the original repository in your own GitHub account. However, the original repository will continue to evolve with new commits and changes. To keep your forked repository up to date with the changes made in the original repository, you need to sync it periodically. Here’s how you can do it:
Step 1: Open the terminal or command prompt on your local machine.
Step 2: Navigate to the local directory where you have the forked repository cloned.
Step 3: Add the original repository as a remote.
$ git remote add upstream original_repo_urlReplace original_repo_url with the URL of the original repository.
Step 4: Fetch the latest changes from the original repository.
$ git fetch upstreamStep 5: Merge the changes from the original repository into your local branch.
$ git merge upstream/masterStep 6: Push the changes to your forked repository on GitHub.
$ git push origin masterAfter following these steps, your forked repository will be synchronized with the latest changes from the original repository. You can now continue working on your forked repository without missing any updates.

Dealing with Merge Conflicts
When updating a forked repository in GitHub, it’s important to be aware of potential merge conflicts that may arise. Merge conflicts occur when changes have been made to the same lines of code in both the original repository and the forked repository. Resolving merge conflicts requires careful attention and collaboration with other contributors.
Identifying Merge Conflicts
To identify merge conflicts, you’ll need to pull the latest changes from the original repository into your forked repository. This can be done using the following steps:
- Ensure you are on the correct branch in your forked repository.
- Fetch the latest changes from the original repository by adding it as a remote:
git remote add upstream [original repository URL]. - Fetch the latest changes from the original repository by running:
git fetch upstream. - Merge the changes into your local branch:
git merge upstream/[branch name].
After executing these steps, Git will attempt to merge the changes automatically. However, if there are conflicting changes, Git will mark them as merge conflicts and modify the affected files with conflict markers indicating the conflicting lines.
Resolving Merge Conflicts
To resolve merge conflicts, follow these steps:
- Open the affected files in a text editor or an integrated development environment (IDE) that supports merge conflict resolution.
- Locate the conflict markers, which are usually denoted by
<<<<<<<,=======, and>>>>>>. - Review the conflicting changes within the conflict markers and decide how to resolve the conflicts.
- Edit the file to remove the conflict markers and ensure the code reflects the desired changes.
- Stage the resolved changes:
git add [file path]. - Continue the merge process by running:
git commit. - Push the changes to your forked repository:
git push.
It's important to communicate and collaborate with other contributors when resolving merge conflicts, especially if multiple developers have made conflicting changes. By discussing and agreeing on the resolutions, you can ensure a more cohesive and error-free codebase.
Tips for resolving merge conflicts when updating the forked repo
Updating a forked repository is a common task for many developers. However, this process can sometimes lead to merge conflicts, which occur when the changes in the original repository cannot be smoothly merged with the existing changes in the forked repository. Resolving merge conflicts can be a challenging task, but with the right approach, it can be done effectively.
1. Understand the conflict
When you encounter a merge conflict, it's important to understand what caused it. Take a close look at the conflicting files and the specific lines that are causing the conflict. Understanding the changes made in the original repository and the changes made in your forked repository will help you make informed decisions on how to resolve the conflict.
2. Use a visual merge tool
Using a visual merge tool can make the process of resolving conflicts much easier. These tools provide a side-by-side comparison of the conflicting changes and allow you to choose which changes to keep. Some popular visual merge tools include Beyond Compare, KDiff3, and P4Merge. Explore different tools and choose the one that works best for you.
3. Resolve conflicts manually
If you prefer to resolve conflicts manually, you can directly edit the conflicting files using a text editor. Look for the conflict markers, which are typically <<<, ===, and >>>, and manually modify the file to incorporate the desired changes. Be careful to preserve the desired changes from both the original repository and your forked repository.
Remember to remove the conflict markers and any unnecessary code that might have been added during the conflict resolution process. Once you have resolved all conflicts, save the changes and commit them to complete the merge.
4. Test your changes
After resolving the merge conflicts, it's essential to thoroughly test the changes to ensure that everything is working as expected. Run any relevant tests, check for any unexpected behavior, and verify that both the original repository's changes and your forked repository's changes have been successfully merged.
By following these tips, you can effectively resolve merge conflicts when updating your forked repository. Remember to carefully analyze the conflicts, use visual merge tools if necessary, resolve conflicts manually when desired, and thoroughly test the changes before finalizing the merge.
