Akousafatal: Unable to create lock fileA Git lock file (.lock) exists, preventing the operation.
A previous Git operation was interrupted or crashed, leaving behind a lock file (usually .git/index.lock). Another Git process may also be running concurrently.
Ensure no other Git processes are running. Remove the stale lock file: rm -f .git/index.lock. If using a GUI client, close it first. On Windows, a background process may hold the file; check Task Manager.
rm -f .git/index.lockCONFLICT (content): Merge conflictGit could not automatically merge changes because the same lines were modified in both branches.
