Comment 21 for bug 1581864

I tested the PPA build for Bionic (1.14.0-0ubuntu1.3) and it does not work:

# start nginx in background (as it hangs):
$ sudo systemctl start nginx &

# the parent PID is written to the PIDFile:
$ cat /run/nginx.pid
807

# eventually systemctl start fails and status:
$ systemctl status nginx
