This can happen when your branch on the remote is ahead of your local branch and you go to deploy.
Solution 1: Shift click the git drop down and hit "pull remote changes".
Note that this will overwrite any local changes (anything you've saved without committing) since your last commit.
Solution 2: If pulling from remote doesn't work due to a conflict with files, and it's a relatively small amount of files causing a conflict, save them externally, deleted them from the project, and then try pulling remote changes again. Then you can add the files back by dragging and dropping them into the project.
