Linux : error processing package nginx on Debian

By | May 29, 2015

Having this error trying to install Nginx on Debian Linux 8?

dpkg: error processing package nginx (–configure):
dependency problems – leaving unconfigured
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

This is a known behaviour if you have Apache or another Web server installed and running. The problem is caused by another daemon or service listening on port tcp-80.

Either uninstall the other service or stop it to allow Nginx installation. Then adjust your configuration accordingly.
