In the process of using Git version control tool, you will inevitably encounter some problems. One of the common problems is GitLab push error. When you try to push local code to a remote repository, you may encounter various push errors, such as "rejected non-fast-forward", "failed to push some refs", etc. These mistakes can leave you feeling frustrated and helpless. But don't worry, the solutions to these errors are often simple.
In this article, we will introduce common GitLab push errors and solutions.
- rejected non-fast-forward
This error usually occurs when you try to push code to a branch where the code already exists. The solution to this error is to merge the branches. You can merge other branches into your local branch using the following command:
git merge <branch></branch>
If you still receive the "rejected non-fast-forward" error when pushing code to the remote repository, you can use the following command Force push code:
git push -f origin <branch></branch>
NOTE: Force push may delete code in the remote repository, so please think twice before doing so.
- failed to push some refs
If you encounter a "failed to push some refs" error when trying to push code to a remote repository, this may be because You did not update the local code base. Before pushing the code, you should use the following command to get the latest code:
git pull origin <branch></branch>
Then try to push the code again. If the problem persists, consider using the following command to force push:
git push -f origin <branch></branch>
However, please note that force push may delete code in the remote code base, so please think twice before proceeding.
- permission denied (publickey)
This error usually means that you are trying to access GitLab via SSH, but the SSH key is not configured correctly. To fix this issue, you need to generate a new SSH key and add it to GitLab. SSH keys can be generated using the following command:
ssh-keygen -t rsa -C "youremail@example.com"
Then add the public key to your GitLab account.
- remote: GitLab: You are not allowed to force push code to a protected branch on this project
This error usually occurs when you try to force push code to a protected branch Protected branches. GitLab protects some common branches by default, such as master and develop. To solve this problem, you can create a new branch using the following command:
git checkout -b <new_branch></new_branch>
Then commit your changes to the new branch and push it to the remote repository.
- error: failed to push some refs to 'git@gitlab.com:user/repo.git'
This error usually means that you do not have permission to push the code to the remote warehouse. This may be because you are trying to push code to a GitLab project that is not yours. Please make sure you have write permission for the project.
The above are some common GitLab push errors and solutions. It's normal to encounter problems when using GitLab version control tools. However, the key to solving the problem is to stay calm and use the correct commands and techniques to solve the problem. If you still can't resolve the issue, search the GitLab documentation or ask the GitLab community for further help and support.

GitHub is not just a version control tool, it also provides collaboration, project management and community communication capabilities. 1) Version control: Use Git to track code changes. 2) Collaboration: Submit code changes through PullRequest. 3) Project management: Use Issues and Project sections to manage tasks. 4) Community communication: Learn and communicate through fork and participating in open source projects.

Git and GitHub are different tools: Git is a version control system, and GitHub is an online platform based on Git. Git is used to manage code versions, and GitHub provides collaboration and hosting capabilities.

GitHub is a distributed version control system based on Git, providing the core features of version control, collaboration and code hosting. 1) Creating repositories, cloning, committing and pushing changes is the basic usage. 2) Advanced usage includes using GitHubActions for automation, deploying static websites in GitHubPages, and using security features to protect code. 3) Common errors such as merge conflicts, permission issues and network connection issues can be debugged by manually resolving conflicts, contacting the warehouse owner and setting up a proxy. 4) Methods to optimize workflows include using branching strategies, automated testing and CI/CD, code review, and keeping documentation and annotations clear.

Git and GitHub are different tools: Git is a distributed version control system, and GitHub is an online collaboration platform based on Git. Git manages code through workspaces, temporary storage areas and local warehouses, and uses common commands such as gitinit, gitclone, etc. GitHub provides functions such as code hosting, PullRequest, IssueTracking, etc. The basic process includes creating repositories, pushing code, and collaborating with PullRequest.

Git and GitHub are key tools for modern software development. Git provides version control capabilities to manage code through repositories, branches, commits and merges. GitHub provides code hosting and collaboration features such as Issues and PullRequests. Using Git and GitHub can significantly improve development efficiency and team collaboration capabilities.

Git is a distributed version control system developed by Linus Torvaz in 2005, and GitHub is a Git-based code hosting platform founded in 2008. Git supports branching and merges through snapshot management files, and GitHub provides pull requests, problem tracking and code review functions to facilitate team collaboration.

Git and GitHub are key tools in modern software development. Git is a distributed version control system, and GitHub is a Git-based code hosting platform. Git's core features include version control and branch management, while GitHub provides collaboration and project management tools. When using Git, developers can track file changes and work together; when using GitHub, teams can collaborate through PullRequests and Issues.
