This error is Git’s way of saying: "I can't just stack your new commits on top of the remote ones because the history has split."

In technical terms, your local history and the remote history have diverged. You have commits that the server doesn't, and the server has commits that you don't. Git is refusing to "Fast-Forward" (which essentially means "just move the pointer forward") because there is nowhere straightforward to move it to.

Here are 5 ways to solve this, ranked from "Standard Practice" to "Nuclear Option."

Docusaurus provides a powerful feature that displays the last updated time and last updated author for every blog post and documentation page.
However, when deploying a Docusaurus website on Vercel, many developers encounter the same confusing issue:

Every page shows the exact same “last updated” date — or no date at all.

This guide explains precisely why this happens and the exact configuration you must enable on Vercel to make Docusaurus timestamps work correctly.

The Git error message "detected dubious ownership in repository" is a modern security feature introduced in Git version 2.35.2 (and backported to several older versions) [1].

This error occurs when you attempt to run Git commands (like git status, git pull, or git commit) inside a repository whose files are owned by a different user ID (UID) than the one currently executing the Git command.

The primary purpose is to prevent privilege escalation or arbitrary code execution when working on shared systems or filesystems that allow one user to create a malicious .git/hooks file that another user (especially one with higher privileges) might unknowingly execute [2].

You can check the history of a specific line in VS Code using the built-in Git Blame feature or the Timeline view. For a much more powerful experience, the free GitLens extension is highly recommended.

Squashing commits is a common Git operation that combines multiple commits into a single, cleaner commit. This is crucial for keeping your branch history tidy before merging into a main branch (like main or master), making the project history easier to read and revert [1].

The primary tool for squashing commits is interactive rebase (git rebase -i).

A common and reliable way to get a fresh copy from a GitHub repository, while preserving specific local files like .gitignore, is to use a combination of git reset and git clean. This approach ensures your local branch exactly mirrors the remote branch, without leaving behind any untracked or unwanted files.

To discard all your local changes and pull the latest version from a GitHub repository, you need to completely reset your local branch to match the remote's state. This process involves a few steps to ensure all uncommitted and committed local changes are removed.

This guide covers the most reliable methods, including situations where you've already made local commits.

Conventional Commits is a lightweight convention on top of commit messages. It provides an easy set of rules for creating an explicit commit history, which makes it easier for automated tools to parse and for humans to understand (1).

How to Fix "You have divergent branches" Error​

The "You have divergent branches" error is a Git warning, not a hard error that stops your operation. It appears when your local branch and the corresponding remote branch have both moved forward, creating a divergent history. Git is telling you that a simple fast-forward merge is not possible and you need to choose a strategy to reconcile the differences before your next git pull.

The error message itself provides the three main solutions: merge, rebase, or fast-forward only.

The error error: 'main/' does not have a commit checked out occurs when Git tries to add files to a submodule that is in a detached HEAD state or has no checked-out commit. This happens because the main repository expects the submodule to point to a specific commit, but it's in an invalid state.

To fix this, you need to navigate into the submodule's directory and check out a commit, usually by switching to the main branch or a specific branch.
