Installing java 9 fails on ubuntu - 404 error

I'm trying to install java 9 on ubuntu 16.04, using the webupd8team repo. I've installed java 8 already on the same machine. Running the following commands

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java9-installer

leads to a 404 error for the last command:

Using wget settings from /var/cache/oracle-jdk9-installer/wgetrc

download failed
Oracle JDK 9 is NOT installed.

Is there a way to change the url, or doesn't the webupd8team's repo work anymore?

Answer Source

java.net site is closed now and web-upd8 repository cannot get JDK sources from there. I suggest you to download JDK 9 from Oracle site and install it manually according to installation instructions
