GH013: Repository rule violationsUpload local project to GitHub, HTTPS/SSH authentication, remote origin, main/master, non-fast-forward, Pull Request, merge conflict, private/public repo, protected branch, large file and secret issues in one place.
Do not perform a reset or force operation without seeing `git status`, active branch, remote and last commits.
Check that the HTTPS credential, SSH key, remote URL and GitHub account are correct.
Leave a rollback point with a commit or backup branch before fetching, merging or rebase.
Use feature branch flow instead of bypassing protected branch, review, CI and secret scanning rules.
Don't commit tokens, private keys, or customer data to `.env` or.
Meaning: Upload your project to GitHub on Windows, macOS, and Linux computers. Learn the steps git init, add, commit, remote origin, main branch, and git push.
Possible cause: Git Initial Setup and First Push
Meaning: Solve GitHub Authentication failed, invalid username or token and Permission denied publickey errors with PAT, Git Credential Manager and SSH key.
Possible cause: GitHub Authentication
Meaning: Resolve the remote origin already exists, repository not found and no such remote errors. Remote URL viewing, editing, deleting and HTTPS–SSH switching.
Possible cause: Git Remote and Repository URL
Meaning: src refspec main does not match any error: first commit, main–master branch difference, wrong branch name, empty repository, and detached HEAD are checked.
Possible cause: Branch and Initial Commit Errors
Meaning: Failed to push some refs and non-fast-forward error can be resolved without losing data by checking with git fetch, pull, merge, rebase, and unrelated histories.
Possible cause: Remote Timeline and Non-Fast-Forward
Meaning: Create a feature branch on GitHub, commit and push, open a Pull Request. Learn about base–compare branch, draft PR, reviewer and merge methods.
Possible cause: Branch Workflow and Code Review
Meaning: Solve GitHub Pull Request merge conflict issues with web, terminal, VS Code, merge and rebase methods. Manage conflict markers and branch updates.
Possible cause: Merge, Rebase and Conflict Resolution
Meaning: Learn the difference between private and public GitHub repositories. Change visibility, add collaborators, grant permissions, fork, license, and hidden file security.
Possible cause: Repository Visibility and Permissions
Meaning: Clone and pull operations for private GitHub repositories via HTTPS, PAT, and SSH. Solve repository not found, permission denied, and access denied errors.
Possible cause: Clone, Fetch, and Private Access
Meaning: Safely solve GitHub protected branch, repository rule violation, file exceeds 100 MB, secret detected, and push limit errors.
Possible cause: Protected Branch, Ruleset, and Push Protection

git pushgit push origin mainfeature branch → PR → review/CI → mergeGit for Windows, PowerShell, Git Bash, and VS Code Source Control can be used together.
HTTPS credential manager; SSH is available for long-term and multi-account development environments.
Repository role, protected branch, Pull Request, and CI policies must be managed together.
Git is a local version control system; GitHub is a Git repository hosting and collaboration platform.
Push commits to remote; fetch remote information; pull fetch and apply merge or rebase afterwards.
Clone comes with Git history and remote connection; ZIP is just a snapshot of files.
It is technically a branch name; repository policy and default branch setting are important.
Can be provided with separate repository or collaborator access; unnecessary access to the main product repository should not be given.
No; this can cause loss of commit history and remote connections.
Provides correct redirect from terminal error message and a robust internal SEO content set.
We examine Windows, VS Code, Git Bash, SSH, private repository, protected branch, merge conflict and GitHub Actions problems with a secure Git flow.
