Now there's a GitHub button that does this! :D
When you fork a project and it goes too far, you need to resync your fork.
I usually reset whole master branch and then checkout a new one to make a new PR...
If you don't have upstream configured when you run git remote -v, do this:
git remote add upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.gitthen do the main stuff, from master branch:
git fetch upstream
git merge upstream/master
git reset --hard upstream/master
git push origin masterIf last line doesn't let you, just do git push origin master --force. #YOLO
