As far as I can tell, the nginx web server seems to fail to start after
installing as some other program already installed (like apache?) is using
port [::]:80, or you either have to enable ipv6 on your system, or
configure nginx web server to use ipv6 only.

Some ideas here, among other links:
https://stackoverflow.com/questions/14972792/nginx-nginx-emerg-bind-to-80-failed-98-address-already-in-use

Ultimately this is more of an nginx web server setup/config/environment
issue, and less a KDE/Kubuntu one, so there may not be many with the
related experience or knowledge here.
