Fatal error in commit_refs when trying to push Github

Are you trying to push changes to your GitHub repository but keep encountering a fatal error in commit refs? This error can be frustrating, especially when you’re not sure what’s causing it or how to fix it. In this article, we’ll explain the reasons behind this error and provide you with step-by-step instructions on how to resolve fatal error in commit_refs when trying to push Github.

Understanding the Fatal Error in Commit Refs

When you commit changes to your Git repository, Git creates a new commit object that includes a pointer to the previous commit object. This creates a chain of commits that you can use to track changes to your repository over time. The pointer to the previous commit is known as a “commit ref.” The fatal error in commit refs occurs when Git cannot create or update a commit ref.

Causes of the Fatal Error in Commit Refs

Encountering a fatal error in commit refs when trying to push on Github can be caused by several factors. Here are some of the most common causes of this issue:

Git Repository Corruption

If your Git repository is corrupted, it can cause issues with commit refs, preventing Git from creating or updating them. This can happen due to a variety of reasons, such as hardware failures, power outages, or incorrect usage of Git commands.

Concurrent Updates

If multiple users are updating the same repository at the same time, it can cause conflicts that prevent Git from creating or updating commit refs. This can happen when multiple users push changes simultaneously, without pulling changes first.

Authentication Issues

If you’re not properly authenticated with Github, you may not have the necessary permissions to create or update commit refs. This can happen if your Github credentials are incorrect, or if you’re trying to push changes to a repository that you don’t have access to.

Insufficient Disk Space

If you don’t have enough disk space on your local machine or on the Github server, Git may not be able to create or update commit refs. This can happen if you’re working with large files, or if your repository has grown too large over time. By understanding the causes of fatal error in commit refs on Github, you can take steps to prevent this issue from occurring in the first place, or quickly diagnose and fix it when it does happen.

How to Fix the Fatal Error in Commit Refs?

Now that you understand the possible causes of the fatal error in commit refs, let’s look at how you can fix it. Here are the steps to follow:

Fix 1: Check for Git Repository Corruption

If your Git repository is corrupted, it can cause issues with commit refs, preventing Git from creating or updating them. To fix this issue, you can check for Git repository corruption and repair it if necessary. Here are the steps to follow:

  • Step 1: Open your terminal or command prompt and navigate to your local Git repository.
  • Step 2: Run the “git fsck” command to check for any corruption in your Git repository.
  • Step 3: If corruption is detected, you can try to repair it using the “git gc –prune=now” command. This will remove any unnecessary objects in your repository and help repair any corruption.
  • Step 4: After running the command, try pushing your changes to Github again and see if the error is resolved. If not, move on to the next fix.

Note: If your repository is heavily corrupted, you may need to consider creating a new repository and transferring your changes to the new repository.

It’s important to regularly check for Git repository corruption to prevent issues like this from occurring in the future. You can do this by running the “git fsck” command periodically and making sure your repository is up-to-date.

Fix 2: Pull Changes from Github

If multiple users are updating the same repository at the same time, it can cause conflicts that prevent Git from creating or updating commit refs. To fix this issue, you can pull any changes that may have been made by other users before pushing your own changes. Here are the steps to follow:

  • Step 1: Open your terminal or command prompt and navigate to your local Git repository.
  • Step 2: Run the “git pull” command to pull any changes that may have been made by other users. This will update your local repository with any changes that have been made on Github.
  • Step 3: After pulling changes, resolve any conflicts that may have occurred. This can be done by opening the conflicting file, resolving the conflicts, and then committing the changes.
  • Step 4: Once conflicts have been resolved, push your changes to Github again and see if the error is resolved. If not, move on to the next fix.

Note: It’s important to regularly pull changes from Github to ensure your local repository is up-to-date with the latest changes made by other users. This can help prevent conflicts and errors in the future.

Fix 3: Verify Authentication

If you’re not properly authenticated with Github, you may not have the necessary permissions to create or update commit refs. To fix this issue, you can verify your authentication with Github and make sure you have the necessary permissions. Here are the steps to follow:

  • Step 1: Open your terminal or command prompt and navigate to your local Git repository.
  • Step 2: Run the “git config –list” command to check your Github credentials. This will show you the username and email address associated with your Github account.
  • Step 3: If your Github credentials are incorrect, you can update them using the “git config” command. For example, to update your username, you can run the “git config –global user.name [your username]” command.
  • Step 4: After updating your Github credentials, try pushing your changes to Github again and see if the error is resolved. If not, move on to the next fix.

Note: It’s important to make sure your Github credentials are up-to-date and accurate to ensure you have the necessary permissions to push changes to Github.

Fix 4: Check Disk Space

If you don’t have enough disk space on your local machine or on the Github server, Git may not be able to create or update commit refs. To fix this issue, you can check your disk space and make sure you have enough space available. Here are the steps to follow:

  • Step 1: Open your terminal or command prompt and navigate to your local Git repository.
  • Step 2: Run the “df” command to check your disk space. This will show you how much disk space you have available on your local machine.
  • Step 3: If you’re running low on disk space, you can free up space by deleting unnecessary files or moving files to an external hard drive.
  • Step 4: If you’re running low on disk space on the Github server, you may need to upgrade your Github plan to get more storage space.
  • Step 5: After freeing up disk space, try pushing your changes to Github again and see if the error is resolved. If not, move on to the next fix.

Note: It’s important to regularly check your disk space to ensure you have enough space available to work with Git and Github. This can help prevent issues like this from occurring in the future.

Fix 5: Try a Force Push

If none of the above fixes work, you can try a force push using the “git push -f” command. This will overwrite any conflicting changes on the Github server, so use this option with caution. Here are the steps to follow:

  • Step 1: Open your terminal or command prompt and navigate to your local Git repository.
  • Step 2: Run the “git push -f” command to force push your changes to Github. This will overwrite any conflicting changes on the Github server.
  • Step 3: After running the command, check your Github repository to make sure your changes have been successfully pushed.

Note: Force pushing should only be used as a last resort, as it can overwrite any conflicting changes on the Github server. It’s important to pull changes before pushing and try other fixes before resorting to a force push.

Fix 6: Use Git LFS

If you’re encountering the fatal error in commit refs when trying to push large files to Github, you may need to use Git LFS (Large File Storage). Git LFS is an extension to Git that allows you to store large files outside of your repository, reducing the size of your repository and preventing issues with commit refs. Here are the steps to follow:

  • Step 1: Install Git LFS on your local machine by following the installation instructions provided by Github.
  • Step 2: Update your Git repository to use Git LFS by running the “git lfs install” command.
  • Step 3: Add the large files you want to push to your repository using the “git lfs track” command. For example, if you want to track all .mp4 files, you can run the “git lfs track ‘*.mp4′” command.
  • Step 4: Commit and push your changes to Github as usual. Git LFS will automatically upload the large files to a separate storage location outside of your repository.

Note: Using Git LFS can help prevent issues with commit refs when pushing large files to Github. However, it’s important to make sure your Git LFS installation is up-to-date and properly configured to ensure it works correctly.

Fix 7: Clone Repository Again

If none of the above fixes work, you can try cloning your repository again. This will create a fresh copy of your repository on your local machine and may help resolve any issues with commit refs. Here are the steps to follow:

  • Step 1: Open your terminal or command prompt and navigate to the directory where you want to clone your repository.
  • Step 2: Run the “git clone” command followed by the URL of your Github repository. For example, if your Github repository URL is https://github.com/username/repository.git, you would run the command “git clone https://github.com/username/repository.git”.
  • Step 3: Once the repository has been cloned, make any necessary changes and try pushing your changes to Github again.

Note: Cloning your repository again can be a time-consuming process, especially if you have a large repository with many files. However, it can be a useful fix if all other options have been exhausted.
