拒绝主人- master fetch first error failed to push some refs to git github com abc70 new git

I am getting the below error when trying to push data fromlocal to GitHub.

! [rejected] master -> master (fetch first) error: failed to push some refs to '[email protected]:abc70/new.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.
