  • The JRE of OpenJDP 8 is already installed successfully (“`openjdk-8-jre` is already the newest version (`8u151-b12-0ubuntu0.16.04.2`).”) but there’s a broken Oracle Java 7 installation. Do you want to keep it or remove it? The answer (or duplicate link) is going to depend on that. – David Foerster Feb 10 '18 at 07:54
  • @DavidFoerster -- I think Java7 has been obsoleted, so removal is his only option – ravery Feb 10 '18 at 14:06
  • @ravery: Some people have sensible reasons to keep (Oracle) Java 7 and it's still possible to install it from old packages and/or tar balls. – David Foerster Feb 10 '18 at 16:12
  • @DavidFoerster - true. I meant that the oracle archive that the installer is trying to access may not exist anymore. – ravery Feb 10 '18 at 17:04

From the terminal log it shows you already have openjdk8 installed. you can check by typing

java -version

you should see a response like this

java version "1.8.0_72"
Java(TM) SE Runtime Environment (build 1.8.0_72-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.72-b15, mixed mode)

I believe you have multiple java versions running, and your machine is trying to fetch an update.
