Answer
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.
