title: How can I rollback a git repository to a specific commit?
body: <p>My repo has 100 commits in it right now. I need to rollback the repository to commit 80, and remove all the subsequent ones.</p>
  <p>Why?</p>
  <p>This repo is supposed to be for merging from miscellaneous users. A bunch of merges went in as commits from me, due to excessive editing. That was due to a mislabeling of my remote branches, where 3 developers were labeled as each other. I need to reset to that point, and then pull forwards.</p>
  <p>I wanted to rebase, as in this example: <a href="https://stackoverflow.com/questions/448919/how-can-i-remove-a-commit-on-github">How can I remove a commit on GitHub?</a></p>
  <p>However, git wants me to do a lot of conflict management. Is there a simpler way?</p>
