Cant upgrade NGINX, overwrite issue?

Trying to update NGINX:

apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 nginx : Depends: nginx-core (< 1.9.3-1ubuntu1.1.1~) but 1.9.3-1ubuntu1.2 is installed or
                  nginx-full (< 1.9.3-1ubuntu1.1.1~) but it is not installed or
                  nginx-light (< 1.9.3-1ubuntu1.1.1~) but it is not installed or
                  nginx-extras (< 1.9.3-1ubuntu1.1.1~) but it is not installed
E: Unmet dependencies. Try using -f.

So I try using -f install:

apt-get -f install
