Public bug reported:

After updating libssl and related packages, nginx will no longer
autostart at system boot.

Immediately after boot, nginx.service is in a failed state.

# service nginx status
● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: 
enabled)
   Active: failed (Result: timeout) since Fri 2018-08-24 21:27:51 UTC; 32min ago
     Docs: man:nginx(8)

The service can be manually started after boot.

This happens on an ARMHF based microcontroller running ubuntu 18.04.2 raspi 
server distribution with a stock kernel.org 4.9-181 kernel.

Ubuntu repositories are not accessible from the device, so packages are
copied to the device, and apt install is used to upgrade them:

apt install --no-install-recommends $dir/updates/system/*.deb  | logger
2>&1


The following is a list of packages that, when upgraded, cause the nginx 
systemd service to fail to autostart at boot.

nginx is used primarily as an https front-end for web services on the device.

libssl is the core dependency for all of the packages in the group that,
when upgraded, causes nginx to fail.

The nginx configuration includes the following SSL settings:


http {
        ##
        # SSL Settings
        ##

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
        ssl_prefer_server_ciphers on;
}

server {
  listen              443 ssl;
  ssl_certificate     /etc/certs/cert.crt;
  ssl_certificate_key /etc/certs/cert.key;
  ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers         HIGH:!aNULL:!MD5;
}
