Root Cause & Mechanism Analysis

Why does this error occur?

You checked out a specific commit hash, tag, or remote branch directly rather than a local tracking branch.

Will I lose my changes if I checkout main directly?

Any commits made in detached HEAD will become orphaned. Creating a branch first preserves them permanently.

Merge repositories initialized independently with different initial commits using --allow-unrelated-histories.

Resolve SSH authentication failures caused by wrong file permissions, missing keys, or SSH agent issues.

Identify and terminate conflicting host processes or adjust Docker port mapping to resolve port bind collisions.
