Root Cause

Git repository is corrupted. HEAD or objects are broken.

generic

Workarounds

  1. 90% success Try git fsck to identify corrupted objects 
    # Run filesystem check:
git fsck --full

# This will report:
# broken link, missing blob/tree/commit, dangling objects
# Fix missing objects by fetching from remote:
git fetch origin

    Sources: https://git-scm.com/docs/git-fsck

  2. 85% success Recover HEAD: git reflog to find last good commit, then git reset 
    git reflog
git reset --hard <good-commit>

    Sources: https://git-scm.com/docs/git-reflog

  3. 80% success If remote is intact, backup local branches then re-clone 
    # Backup current work:
cp -r .git .git.bak
git stash  # if possible

# Re-clone and restore branches:
git clone <remote-url> fresh-clone
cd fresh-clone
# Copy any local-only branches from backup if needed

Dead Ends

Common approaches that don't work:

  1. Delete .git and re-clone 70% fail

    Loses all local branches, stashes, and unpushed commits

  2. Run git gc --aggressive 75% fail

    gc can't fix corrupted objects — may make things worse
