Sometimes a pull request/merge request needs changes before it can be merged. On GitHub, a typical workflow is like:
git switch -c feature main git pull https://github.com/friend/repo.git main # other person's repo branch PR/MR is from
Then one edits the files, and commits the changes. However, if the Git pull command fails like:
fatal: Not possible to fast-forward, aborting.
Then ensuring you’re in the new feature branch:
git pull https://github.com/friend/repo.git main git reset FETCH_HEAD --hard
Then one edits the files, and commits the changes.
Finally, the generic workflow to merge the PR/MR is:
git switch main git merge --no-ff feature git push
