Updates were rejected because the tip of your current branch is behind its remote counterpart

The -f is actually required because of the rebase. Whenever you do a rebase you would need to do a force push because the remote branch cannot be fast-forwarded to your commit. You'd always want to make sure that you do a pull before pushing, but if you don't like to force push to master or dev for that matter, you can create a new branch to push to and then merge or make a PR.

the tip of your current branch is behind its remote counterpart means that there have been changes on the remote branch that you don’t have locally. and git tells you import new changes from REMOTE and merge it with your code and then push it to remote.

You can use this command to force changes to server with local repo ().

git push -f origin master

with -f tag you will override Remote Brach code with your code.

To make sure your local branch FixForBug is not ahead of the remote branch FixForBug pull and merge the changes before pushing.

git pull origin FixForBug
git push origin FixForBug
