Using Ubuntu 10.10, As soon as I change the line back to “Listen 80;”
nginx
works fine.

[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)

Ah,

listen 80;
listen [::]:80 ipv6only=on;*

*rather than simply,

listen [::]:80;
