How to roll back commits on github.com

The situation when you already have a clone of the repository with which you are working, pull and see that there is some kind of garbage commited from the developers.

We select the necessary brunch (branch), I have it master
git checkout master

roll back the changes in the repository for an example two commit backwards
git reset --hard HEAD ~ 2

You can make up to a specific commit by hash
git reset --hard HEAD hash
Hash can be taken on the web interface of the github.

Next, we make a forced commit in the main repo on the githab
git push -f origin master
without -f swearing that you have a version younger than in the github and you need to do pull
