Associar Projeto com GitHub

Ao comitar projeto para GitHub apresenta essa mensagem de erro:
fatal: The current branch master has no upstream branch.
To push the current branch and set the remote as upstream, use

git push --set-upstream origin master

Parece que vc já tem o remote adicionado como origin porém a branch master local ainda não está associada com a master do remoto.

Pela mensagem, basta vc executar esse comando que deve funcionar:

git push --set-upstream origin master

Deu esse erro:

error: src refspec master does not match any
error: failed to push some refs to ‘github.com:Tiagotsa/dsmovie.git’

Ah sim, o Github não está mais usando o nome master como branch. Agora vc deve usar main. Que é a branch que está no seu repositório do github.

Parece que isso é por conta da referência com a escravatura (master-slave). E o nome main fica mais apropriado.

Ainda continua com erro, segue todo processo:

Posta o resultado completo do comando git status pra gente ver.

é esse resultado mesmo

O git status deve retornar algo parecido com isso:

lucas@lucas-G3-3579:~/Documentos/git/flutter/probabilidades_brasileirao$ git status
No ramo main
Your branch is up to date with 'origin/main'.

Changes not staged for commit:
  (utilize "git add <arquivo>..." para atualizar o que será submetido)
  (use "git restore <file>..." to discard changes in working directory)
	modified:   android/app/build.gradle
	modified:   android/build.gradle
	modified:   pubspec.lock

nenhuma modificação adicionada à submissão (utilize "git add" e/ou "git commit -a")

não entendi muito bem, como usar o comando, fiz assim.
git restore <index.html>
bash: syntax error near unexpected token `newline’

não é git restore, é git status.

Abra o terminal, digite git status, copie o resultado, e poste aqui pra gente.

A branch main do remoto possui commits que sua main local não tem. Tem que ver o que está valendo, se é as mudanças que vc fez localmente, ou os commits que estão no remoto.

como faz isso?

Veja lah no github se as mudanças que estão lá são as que vc quer, em vez das mudanças locais. Se for, vc pode descartar as mudanças locais usando o git reset.

Agora se as mudanças que estão localmente forem mais importantes do que as que estão lá no github vc pode forçar o push com a opção -f: git push -f origin main.

Outra coisa seria fazer o pull, ver se vai dá conflito e, se der, vc corrige o conflito e faz o push normalmente.

Pelo que vi, no github, só tem um arquivo index.html. Vc tem mais arquivos criados/alterados localmente?

sim

Então vc pode forçar o push mesmo.
