Git Ошибка : Updates were rejected because the remote contains work that you do not have locally

Написал обнову для своего проекта, но при использовании git push --set-upstream origin master пишет :

    To https://github.com/Dertfin3051/DFPOS.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://github.com/Dertfin3051/DFPOS.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

При этом мне не нужно использовать git pull, так как я только написал обновление, и после пула придётся делать обнову заново. Что делать?
