While using Git, I encountered the error message “fatal the remote end hung up unexpectedly”. However, with some troubleshooting processes, I was able to resolve it successfully. In this article, we will delve into the possible causes of this issue and explore the steps to resolve it comprehensively.
“fatal the remote end hung up unexpectedly” ERROR indicates an unexpected disconnection between your local repository and the remote repository that you are interacting with.
we will cover the essential troubleshooting steps and shared few examples of the occurrences, along with the corresponding solutions to resolve them.
Quick Introduction to Git
Git, the widely used version control system, allows developers to collaborate effectively by managing changes to their codebase. It is open-source, cross-platform, and provides robust features that facilitate seamless teamwork among developers, enabling them to work on the same project simultaneously.
Why we are seeing “fatal the remote end hung up unexpectedly” and how to resolve it
fatal the remote end hung up unexpectedly Error happens When you have an issue with https & git buffer settings and other causes, Which can cause a disconnection between the local repository and the remote repository like rpc failure, Network issues, etc
$ git push Counting objects: 32341232, done. Delta compression using up to 15 threads. Compressing objects: 100% (3201184/3201184), done. error: RPC failed; result=22, HTTP code = 411 fatal: The remote end hung up unexpectedly
Below are the General troubleshooting steps, that need to be followed to resolve the issue faster
General Troubleshooting Steps:
- Network Connectivity Issues:
First, ensure that you have a stable internet connection. You can check your internet connectivity by accessing websites or performing other network-related tasks. If there are issues with your network, resolve them, and try the Git operation again.
$ ping google.com
If you receive replies, your internet connection is active.
- Authentication Problems:
If the remote repository requires authentication, double-check your credentials (username and password or SSH key) configured in your Git configuration.
$ git config --global user.name $ git config --global user.email
Ensure that the displayed user name and email match your credentials.
- Remote Repository Changes:
Reach out to your team members to inquire about any recent significant changes in the remote repository that could lead to conflicts. Communicate with them to understand the changes made and how you can align your local repository with the remote repository.
$ git fetch $ git log origin/master..master
This will show the commit history that is present locally but not on the remote repository.
- Enable Debug Mode
If the above 1,2 and 3 steps are working fine, Then it would be a good idea to enable debugging in the terminal, Which helps us to get some more information in the terminal
$ set GIT_CURL_VERBOSE=1 $ set GIT_TRACE=1 $ git push
- Large Pushes or Pulls:
If you are dealing with a considerable number of changes or large files, try breaking down your commits into smaller, more manageable chunks.
$ git add -p
This command allows you to interactively select changes to add, allowing you to commit smaller portions.
- Server or Service Issues:
Check the status of the remote repository service, such as GitHub or Bitbucket, to ensure there are no ongoing maintenance or server issues affecting the connection.
Visit the status page of the service or check their official support channels for any announcements.
Example Scenario 1:
Let’s consider a scenario where you are working on a project with a remote Git repository hosted on a service like GitHub. You attempt to push your latest changes to the remote repository using the following command:
$ git push
Upon executing the command, you encounter the following error message:
$ git push Counting objects: 32341232, done. Delta compression using up to 15 threads. Compressing objects: 100% (3201184/3201184), done. error: RPC failed; result=22, HTTP code = 411 fatal: The remote end hung up unexpectedly Writing objects: 100% (32341232/32341232), 748.30 MiB | 84.23 MiB/s, done. Total 32341232 (delta 1849283), reused 3230451 (delta 1849283) fatal: The remote end hung up unexpectedly
In Git the HTTP protocol uses Transfer-Encoding in POST requests, When it contains objects that are greater than 1MB, We will most probability hit this error Because some of the servers do not support the default Transfer-Encoding
To resolve the issue, We can try to increase the buffer used by git from the Unix command by exporting this variable:
$ export GIT_HTTP_MAX_REQUEST_BUFFER=<higher value example 100M> $ git push
The above is for that particular instance, If you want to set it globally, we can try seeing as below
$ git config --global http.postBuffer 157286400 $ git push
Same scenarios, When you attempt to push your latest changes to the remote repository using the following command:
$ git push Enumerating objects: 1007, done. Delta compression using up to 8 threads Compressing objects: 100% (332/332), done. Writing objects: 100% (332/332), 119.29 KiB | 4.38 MiB/s, done. Total 476 (delta 228), reused 151 (delta 101), pack-reused 0 error: RPC failed; HTTP 403 curl 22 The requested URL returned error: 403 send-pack: unexpected disconnect while reading sideband packet fatal: the remote end hung up unexpectedly
HTTP status 403 is “Unauthorized”, So it says that you don’t have the privilege to access or push your changes. So it would be efficient to follow the general troubleshooting steps to check if you have access or not and also enable debug to get some more idea
Double-check your credentials (username and password or SSH key) configured in your Git configuration.
$ git config --global user.name $ git config --global user.email
Most probably, You’re using the correct URL, but you don’t have write permissions to that repo or you attempting to push to is protected and you don’t have permission to push directly to that branch.
Encountering the “fatal: the remote end hung up unexpectedly” error in Git can be frustrating, but with the right troubleshooting approach, it can be resolved efficiently. By checking network connectivity, verifying authentication credentials, understanding remote repository changes, handling large pushes or pulls smartly, and being aware of potential server issues, you can overcome this error and continue collaborating effectively with your team using Git.
