Thanks for filing this bug in Ubuntu.
I installed nginx 1.14.0-0ubuntu1 from the release pocket of Bionic, i.e., no
updates:
root@bionic-nginx:~# apt-cache policy nginx
nginx:
Installed: 1.14.0-0ubuntu1
Candidate: 1.14.0-0ubuntu1
Version table:
*** 1.14.0-0ubuntu1 500
500 http://br.archive.ubuntu.com/ubuntu bionic/main amd64 Packages
And it already has the listen configuration for ipv6:
root@bionic-nginx:~# grep listen /etc/nginx/sites-enabled/default
listen 80 default_server;
listen [::]:80 default_server;
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
# listen 80;
# listen [::]:80;
I then did a quick "git blame" on that file in the git repository, and that
configuration has been there since at least 2014, if I'm reading this correctly:
10:01 $ git blame debian/conf/sites-available/default|grep listen
659cb474c (Kartik Mistry 2013-04-25 12:51:45 +0530 22) listen 80
default_server;
4f4fcce28 (Christos Trochalakis 2014-10-16 13:34:29 +0300 23) listen [::]:80
default_server;
4f4fcce28 (Christos Trochalakis 2014-10-16 13:34:29 +0300 27) # listen 443
ssl default_server;
4f4fcce28 (Christos Trochalakis 2014-10-16 13:34:29 +0300 28) # listen
[::]:443 ssl default_server;
4f4fcce28 (Christos Trochalakis 2014-10-16 13:34:29 +0300 80) # listen 80;
4f4fcce28 (Christos Trochalakis 2014-10-16 13:34:29 +0300 81) # listen [::]:80;
Furthermore, the change introduced in 1.14.0-0ubuntu1.3 is just a
rebuild with the newer openssl library that was updated in bionic:
nginx (1.14.0-0ubuntu1.3) bionic; urgency=medium
* No changes rebuild (to build against OpenSSL 1.1.1 in Bionic)
(LP: #1836366)

If all of a sudden ipv6 was required in an update to a stable release, I'd
agree it's surprising to say the least. Are you sure your server didn't get
ipv6 disabled before this update, and it was only noticed when nginx was
restarted? Has the server always had ipv6 disabled?
If it wasn't failing before, and started to fail now with just the
rebuild with new openssl, that's something that has to be investigated,
but I just want to clear up that point before we dig in, given the above
details I have given.
Thanks!
