You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 nginx : Depends: nginx-full (>= 1.6.2-5+deb8u4) but it is not installed or
                  nginx-light (>= 1.6.2-5+deb8u4) but it is not installed or
                  nginx-extras (>= 1.6.2-5+deb8u4) but it is not installed
         Depends: nginx-full (< 1.6.2-5+deb8u4.1~) but it is not installed or
                  nginx-light (< 1.6.2-5+deb8u4.1~) but it is not installed or
                  nginx-extras (< 1.6.2-5+deb8u4.1~) but it is not installed
E: Unmet dependencies. Try using -f.

The easiest way is to restore from your backup. Alternately you may be able to try using apt to remove the packages that it thinks are still there. I've had to do things like this in the past, I muddled through, but it's fiddly. — Tim, Jun 11 '17 at 23:58
The correct way to uninstall software in Debian / Ubuntu is `apt-get remove`. Other ways will give you issues. — Tero Kilkanen, Jun 12 '17 at 07:40

Try and run the following commands

sudo apt-get remove nginx && sudo apt-get purge nginx
sudo apt-get install nginx

purge delete configuration files for an application, but if it isin't removed first this gives issues.

&& only executes if previous command executed, exited with exit code 0 (successfull) echo $? will show you the exit code of an application.

If all of this fails try and run dpkg -l|grep nginx and look for the first two letters in the output to see the status of the nginx package installation.

Example

ii openssh-server

Try this:

sudo apt-get purge nginx
sudo apt-get install nginx

I'm on ubuntu 14.04 and this worked for me.
