A failed `git commit` or `git push` can feel more alarming than it actually is. In many cases, the failure is not caused by broken code at all. It is usually a **repository state issue, authentication issue, branch mismatch, or missing local Git configuration**.

This note explains the most common reasons `commit` and `push` fail, how to diagnose them systematically, and how to recover safely without making the situation worse.

## The First Rule: Do Not Panic-Repeat Commands

When Git fails, many people immediately run the same command again and again:

```bash
git commit -m "update"
git push
git push
git push
```

That usually does not help.

A better approach is to stop and classify the failure:

- is the problem local or remote?
- is it happening during `commit` or during `push`?
- is it caused by repository state, authentication, or branch tracking?

</Callout>

## Why `git commit` Can Fail

A `git commit` failure happens **before anything is sent to GitHub**. That means the issue is usually local.

### Common causes of failed `git commit`

- `user.name` or `user.email` is not configured
- the repository is in a bad state
- a lock file exists in `.git`
- commit hooks reject the commit
- GPG signing is required but not working
- there is nothing staged to commit

## Case 1: Git Identity Is Missing

This is one of the most common causes, especially on a new machine or a repo that has never been configured locally.

Git needs two values to create a commit author identity:

- `user.name`
- `user.email`

Without them, `git commit` can fail.

### How to fix it

For the current repository only:

```bash
git config user.name "Your Name"
git config user.email "you@example.com"
```

For all repositories on your machine:

```bash
git config --global user.name "Your Name"
git config --global user.email "you@example.com"
```

<Callout variant="tip" title="Important Distinction">
Your GitHub profile URL is not your Git author identity. Git commit uses `user.name` and `user.email`, not your profile link.
</Callout>

## Case 2: Nothing Is Staged

Sometimes the command fails simply because there is nothing to commit.

### How to check

```bash
git status
```

If Git says there are modified files but nothing staged, you need to add them first:

```bash
git add path/to/file
git commit -m "Describe the change clearly"
```

If Git says the working tree is clean, there may be nothing new to commit.

## Case 3: Git Lock File Exists

A previous Git process can leave behind a stale lock file, especially after a crash or interrupted command.

Typical file:

```text
.git/index.lock
```

If that file exists, Git may refuse new operations.

### How to handle it safely

First make sure no Git process is still running.

Then remove the stale lock file manually only if you are certain the old process is gone.

## Case 4: Commit Hooks Block the Commit

Some repositories use hooks such as:

- `pre-commit`
- `commit-msg`
- `pre-push`

These can reject commits if:

- lint fails
- tests fail
- the message format is invalid
- required metadata is missing

### What to do

Check whether the repo has active hooks in `.git/hooks/` or through a hook manager like Husky.

If hooks are active, fix the actual cause instead of bypassing them casually.

## Case 5: GPG Signing or Signing Policy Fails

Some Git environments require signed commits. If GPG or signing is misconfigured, commit creation can fail even though the file changes are fine.

Typical symptom:

- `git commit` fails immediately
- repository state looks normal
- staging is correct
- remote setup is unrelated

### Possible fix

Temporarily disable signing for the current commit if appropriate:

```bash
git -c commit.gpgsign=false commit -m "Your message"
```

Only use this if signing is truly the blocking issue and you understand your repository policy.

## Why `git push` Can Fail

A `git push` failure happens **after commit creation**, when Git tries to talk to the remote.

That means the problem is often one of these:

- authentication failure
- no upstream branch configured
- remote rejected the push
- branch is behind remote
- push permission is missing
- network issue

## Case 6: Authentication to GitHub Fails

If your remote uses HTTPS, Git may require:

- a valid credential helper
- a GitHub token
- a fresh login session

If authentication is invalid, push fails even if commit worked.

### What to verify

```bash
git remote -v
```

Check whether the remote points to the right repository.

Then verify your local credential flow is still valid.

## Case 7: No Upstream Branch Is Set

This usually happens when the current local branch has never been linked to a remote branch.

### Typical fix

```bash
git push -u origin main
```

Replace `main` with your current branch name if needed.

After that, normal `git push` usually works.

## Case 8: Remote Rejects Push Because You Are Behind

If someone else pushed new commits first, your branch may be behind the remote branch.

Git rejects the push to prevent overwriting history.

### Safer fix

```bash
git pull --rebase origin main
git push origin main
```

This keeps history cleaner than unnecessary merge commits in many cases.

<Callout variant="warning" title="Avoid Force Push by Default">
Do not use `git push --force` unless you fully understand the branch history and know it is safe for your workflow. Force pushing is easy to misuse.
</Callout>

## Case 9: Wrong Remote or No Permission

A push can also fail if:

- the remote URL is incorrect
- the repo was moved or renamed
- your account lacks write access
- the branch is protected

### What to inspect

```bash
git remote -v
git branch -vv
```

These commands help confirm:

- which remote is being used
- which branch is current
- whether an upstream branch exists

## A Practical Debugging Sequence

If `commit` or `push` fails, this sequence is usually enough to isolate the issue.

<Steps>
<Step>

### Check repository state

```bash
git status --short --branch
```

This tells you the current branch and whether files are staged.

</Step>
<Step>

### Check branch tracking

```bash
git branch -vv
```

This shows whether your branch is connected to a remote branch.

</Step>
<Step>

### Check remote configuration

```bash
git remote -v
```

This confirms whether `origin` points to the correct GitHub repository.

</Step>
<Step>

### Check local Git identity

```bash
git config user.name
git config user.email
```

If either is missing, fix that first.

</Step>
<Step>

### Commit first, push second

Do not combine too many moving parts when debugging. Make sure `commit` succeeds locally first. Then debug `push` separately if needed.

</Step>
</Steps>

## The Real Lesson

A failed `git commit` and a failed `git push` are not the same class of problem.

### `git commit` problems are usually local

Think:

- identity
- hooks
- locks
- signing
- staging

### `git push` problems are usually remote or branch-related

Think:

- authentication
- upstream tracking
- remote mismatch
- permissions
- branch protection

Once you separate those two layers, Git errors become much easier to solve.

## Recommended Safe Recovery Pattern

When in doubt, use this mental checklist:

1. **Check `git status` first.**
2. **Confirm whether the failure is at `commit` or `push`.**
3. **Verify `user.name` and `user.email`.**
4. **Inspect `git remote -v` and `git branch -vv`.**
5. **Avoid force-pushing unless absolutely necessary.**
6. **Fix the root cause instead of bypassing every guardrail.**

## Key Takeaways

1. **A failed `git commit` is usually a local configuration or repository state issue.**
2. **A failed `git push` is usually an authentication, branch, or remote issue.**
3. **Missing Git identity is one of the most common causes of commit failure.**
4. **Checking `git status`, `git remote -v`, and `git branch -vv` solves many Git mysteries quickly.**
5. **Treat `commit` and `push` as separate debugging stages.**
6. **Do not jump to `--force` unless you truly understand the consequences.**
