If a remote repository has been force updated (
git push -f), the local repository's history must be rewritten to account for it (unless the master is incorrect, in which case a forced update may be the only corrective measure).
A reset with the
--hard flag will
reset the index and working tree. Any changes to tracked files in the working tree since <commit> are discarded
A fetch is necessary first to ensure the remote changes are reflected in the local indexes.
To reset the local repository's HEAD to the remote's HEAD:
$ git fetch $ git reset --hard origin/master
