The error log here indicates that something on your system removed /etc/nginx/nginx.conf and that is why the service cannot start.
The way to solve this is to restore the default configuration file. (1) Back up any configurations in /etc/nginx/sites-available and /etc/nginx/sites-enabled you wish to keep. (2) sudo apt-get purge nginx nginx-common nginx-core (3) sudo apt-get install nginx nginx-common nginx-core This will replace all configurations with the defaults. (4) Restore your configurations you backed up. This is not however a package bug.
