sudo systemctl start nginx.service

ポート80でリッスンしている他のエントリがあります。次の行を確認してください。
duplicate listen 0.0.0.0:80
どの PID が聞いているかを確認するには、次の手順を試してください。
netstat -anp|grep :80
nginxの設定に問題がある場合は、次の最小設定を試してください。
daemon on;
worker_processes 2;
user www-data;
events {
use epoll;
worker_connections 128;
}
error_log logs/error.log info;
http {
server_tokens off;
include mime.types;
charset utf-8;
access_log logs/access.log combined;
server {
server_name localhost;
listen *:80;
error_page 500 502 503 504 /50x.html;
location / {
root html;
}
}
}
