Sometimes you have to get back to the pristine sync with your repo, I created a function in my ~/.bash_profile for that.
# REPO HEAD updated: February 13, 2018
function repo_reset()
{
source activate py27
cd ~/REPO/my-repo-name
pwd
#repo sync
repo forall -vc "git clean -xdf"
repo forall -vc "git reset --hard HEAD"
ls -alt
}
