After a dist-upgrade on my debian machine yesterday I am having some problems with the nginx init script. Whenever I try to start nginx using the init script it comes up with a error message:

# service nginx start
Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.

Output of systemctl status nginx.service:

The nginx daemon file is located in /usr/local/sbin/nginx (I compiled it there).

Things i’ve tried so far:
I copied the daemon file /usr/local/sbin/nginx to /usr/sbin/nginx

When I use service nginx start it hangs on starting nginx. When I try to connect to port 80 it does work. So I proceeded to edit my init script and change PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin to PATH=/usr/sbin:/usr/bin:/sbin:/bin:/usr/sbin:/usr/bin. This however gave the same result.

I haven’t triedd anything else so far.
