Pull is not possible because you have unmerged files, git stash doesn’t work. Don’t want to commit

Question

git fetch origin
git reset --hard origin/master
git pull

Explanation:

Fetch will download everything from another repository, in this case, the one marked as “origin”.
Reset will discard changes and revert to the mentioned branch, “master” in repository “origin”.
Pull will just get everything from a remote repository and integrate.
