executing oracle-java8-installer

[RVDowning]

I already have java7 installed on my system and use it for the android development environment.

If I execute sudo apt-get install oracle-java8-installer I get
Reading package lists... Done
Building dependency tree
Reading state information... Done
oracle-java8-installer is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

So, how does one actually execute oracle-java8-installer to actually do the installation of java8? Or do I have to go to the Oracle site and just download everything myself?

Hello, RVDowning.

The Launchpad Oracle Java (JDK) 7 / 8 / 9 Installer PPA webpage clearly states:

Oracle Java (JDK) Installer (automatically downloads and installs Oracle JDK7 / JDK8 / JDK9). There are no actual Java files in this PPA.

Means, in case Oracle Java 8 installer does not download and install Java 8 on your system, something must be wrong,
+ either with the installed Java 8 installer
+ or on your system
which prevents the installer from doing its job.

The section Install Oracle Java 8 (JDK8 and JRE8) in Ubuntu or Linux Mint on the webpage Install Oracle Java 8 In Ubuntu Or Linux Mint Via PPA Repository [JDK8] holds an explanation on cases where it will indeed be necessary to download the Java 8 .tar.gz installation package from the Oracle Java download page, store it to a particular folder and use the Orcle Java 8 installer then.

Might be worth a try to read the section Install Oracle Java 8 (JDK8 and JRE8) in Ubuntu or Linux Mint carefully.

Regards,
Karl

Downloaded it manually. Still don't know why the installer didn't work. An error message(s) indicating what it didn't like would have been nice.
