error: src refspec main does not match any

Question

I have a local branch named master and its upstream is set to origin/main

But whenever I push to remote repo using git push -u origin main it shows error:

error: src refspec main does not match any error: failed to push some refs to

But it works fine when I use git push -u origin HEAD:main

So what's the Problem in here?

Answer 1

git push origin main means "push local branch main" and you don't have local branch main, you have master. After the first git push -u origin master:main you should push using git push origin or even bare git push. Or continue pushing using git push origin master:main
