Public bug reported:
There is a known issue where NGINX will not properly run or install when
IPv6 is fully disabled on a system.
Per Bug #1712696 which first detailed this, these are some 'relevant'
log entries:
Aug 23 23:52:24 thomas-ThinkPad-T430 nginx[20166]: nginx: [emerg] socket()
[::]:80 failed (97: Address family not supported by protocol)
Aug 23 23:52:24 thomas-ThinkPad-T430 nginx[20166]: nginx: configuration file
/etc/nginx/nginx.conf test failed
Aug 23 23:52:24 thomas-ThinkPad-T430 systemd[1]: nginx.service: Control process
exited, code=exited status=1
Aug 23 23:52:24 thomas-ThinkPad-T430 systemd[1]: Failed to start A high
performance web server and a reverse proxy server.
As you can see the system could not bind to Port 80 on IPv6.
While this is a **nonstandard** setup, there are some systems which are
configured to not have IPv6 support. It should currently be considered
whether we should test for such 'systems' to see whether IPv6 is enabled
or not, and modify the configuration file accordingly during
install/configure.
This issue happens regardless of the 'supported' operating system status
or not, and is a core NGINX package issue, but also a core 'incompatible
configuration' issue with systems which disable IPv6.
