깃 푸시

리눅스에서 블로그 작성하다
윈도우로 넘어오면서 문제가 생겼습니다.
이미 레포지터리가 있었기에 저는

git remote add origin (블로그 url)
git branch -M main
git push -u origin main 을 입력했는데 

! [rejected]        main -> main (fetch first)

error: failed to push some refs to '제 주소'

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.

라고 뜨네요

물론 커밋진행 한후에 일어난 일입니다.
