Code is Safe

SECURE

Git has paused the operation to protect your code. No data has been lost or corrupted.

What To Know

This usually means Git believes another process still owns the staging-area lock, so it refuses to let two writers touch the same index at once.

GitHub/GitLab

The operation was blocked at the staging area. Git cannot prepare or finalize the commit.

Commands That Trigger This

$git commit

Closing the terminal window forcefully while a or git pull was still running

Running a script that executes multiple Git commands asynchronously

Technical Background

The lock file is the concurrency safeguard that guarantees only one process can write to the Git index at a time.

If you are absolutely certain no other Git process is running, the lock file is 'stale' and can be safely deleted manually from the `.git` folder.

Underlying Causes

A previous Git command crashed or was forcefully killed, leaving the lock file behind

An IDE (like VS Code) or GUI tool is running a background fetch at the same time

Two developers running Git commands simultaneously on a shared network drive

Frequently Asked Questions

Yes, provided you have verified that no background Git process or IDE integration is still running.
