git remote -v
git fetch upstream
This command merges the changes that were fetched in the previous step into the local repository's current branch. The --ff-only option ensures that the merge is only performed if it is a fast-forward merge, which means that the local branch has not diverged from the upstream branch.
git merge --ff-only upstream/main
git push origin main
git remote show origin
