There are (at least) two things you can do here–you can reclone the remote repo, or you can reset --hard to the common ancestor and then do a pull, which will fast-forward to the latest commit on the remote master.

To be concrete, here's a simple extension of Nevik Rehnel's original answer:

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

NOTE: using git reset --hard will discard any uncommitted changes, and it can be easy to confuse yourself with this command if you're new to git, so make sure you have a sense of what it is going to do before proceeding.
