Force your forked repo to be the same as upstream.

fork forced sync

git fetch upstream
git reset --hard upstream/master

Works like a charm. Thanks!

This is so great, thank you! @JerryGoyal

what if there are new files in my commit that I want to keep, but changes the upstream made to files that I already have that I also want. When I try to merge upstream, I receive an error: files would be overwritten by merge. But I want them to be overwritten.

can we do this from the GitHub UI?

How can I force users to pull from upstream after a major upgrade of the source code. I have PR validation in place (Jenkins) and they are using the old validation code (python).. ?

Works perfectly. Thanks for the tip.

you may need to also push tags

git push --tags

other variations:

git reset --hard upstream/master
git reset --hard upstream/main
git reset --hard upstream/development

👍

complete git commands would be like this:

git remote add upstream https://github.com/some_user/some_repo
git fetch upstream
git checkout master
git reset --hard upstream/master  
git push origin master --force

Perfect! Thank you!

So this works great locally, but how can I get my GitHub repo master branch to be the same as locally/upstream??

This is possible with a one-liner that doesn't require downloading anything...

For anyone interested in syncing your GitHub-hosted fork directly (without cloning locally first) you can do this using the GitHub CLI:

gh repo sync owner/cli-fork -b BRANCH-NAME
