I'm trying to dowload and install the JDK 8 on my debian with the following command: apt-get install oracle-java8-installer

This is the log I get:

download failed
Oracle JDK 8 is NOT installed.
dpkg: error processing package oracle-java8-installer (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 oracle-java8-installer
E: Sub-process /usr/bin/dpkg returned an error code (1)

Is there something I configured wrong in my firewall or what am I missing?

That package is essentially a packaged script for downloading a Java installer from Oracle.com.

It used to work in the heydays of Debian 8 and Java 8 - it does not work anymore, as the specific Java 8 installation file is not anymore in that location.

The world has simply moved on - also from the error, a 404 not found denotes there exists communication, and is not in any way related to blocked ports/firewall. The other side is answering, it is just it is saying "404 - Not Found".

I would advise using an alternative method for installing the Java framework. The openjdk alternative is more than enough for most projects and is easily installed as:

sudo apt-get install openjdk-8-jdk
