Issue:<\/strong> You are in a detached HEAD state, meaning changes are not attached to a branch.
Fix:<\/strong><\/p>\n\n\n\n

    \n
  1. Check your current HEAD: <\/li>\n<\/ol>\n\n\n\n
    git status<\/code><\/code><\/pre>\n\n\n\n
    2. Attach the changes to a branch: <\/p>\n\n\n\n
    git checkout -b <branch-name><\/code><\/code><\/pre>\n\n\n\n
    3. Commit the changes: <\/p>\n\n\n\n
