You could try to use the official nginx.repo for Ubuntu (Xenial)
Edit /etc/apt/sources.list and add these lines at the end of the file:
deb http://nginx.org/packages/ubuntu/ codename nginx
deb-src http://nginx.org/packages/ubuntu/ codename nginx
Save the file and run this commands:
sudo apt-get update
sudo apt-get install nginx
It should install the latest nginx version from the nginx official repo.
If that's not working try running this command instead:
apt-get -f install nginx
or
apt-get -f -y install nginx
