Question

I’ve forked a repo on github and then made a few changes on master branch.
But I made a mistake, I had to work on a new branch not on the master one.

Can I change branch or should I fork the master again, then make the branch and apply the changes I made?

Answer 1

Rename your local branch:

git branch -m master newbranch

Push it to your remote (let’s say myremote):

git push myremote newbranch

Create a master branch from github’s original remote (say origin):

git branch master origin/master

Forcefully push it:

git push myremote +master:master

This should do it.
