if your upstream branch is not already created, you will need to create it by running the “git push” command with the “-u” option for upstream. 

Errors

git push --set-upstream your-branch
fatal: 'yourbranch' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

Solution: you forgot to add origin

Fatal: The current branch has no upstream branch
