Problems to install nginx-full on debian 8
A similar issue was reported on Debian bug #754407. In the end it was just the port 80 being taken by other process (Apache2). Might this be your case as well?
Stop apache2
service apache2 stop
then install nginx
apt-get install nginx
Then celebrate it!
in my case I executed
sudo apt-get remove nginx* --purge
after that I installed nginx-common
sudo apt-get install nginx-common
then I installed nginx
sudo apt-get install nginx
after this I typed ip in browser and it worked
