Trying to update Java on Linux (Linux installed by Crouton)

  • 772

I wanted to download Minecraft on Linux so I downloaded Java 7, because anything over Java 7 says 

Could not find

so I installed Java 7, but when I try to update Java by entering: 

sudo add-apt-repository ppa:webupd8team/java

it doesn't work. Neither does 

sudo apt update; sudo apt install oracle-java8-installer

Do I need to install something else for Java to work?
I can't add any PPA'S at all, no matter what!

Please help!

software-installation java crouton

  1. I found out yesterday that 'webupd8team' is a private repository, managed by one guy. Exactly one year ago there was a similar problem, and that was a license issue as I understand.

    I fixed it with an answer provided here -> https://ubuntuforums.org/showthread.php?t=2374686

    cd /var/lib/dpkg/info && sudo sed -i 's|JAVA_VERSION=8u181|JAVA_VERSION=8u191|' oracle-java8-installer.*

    sudo sed -i 's|PARTNER_URL=http://download.oracle.com/otn-pub/java/jdk/8u181-b13/96a7b8442fe848ef90c96a2fad6ed6d1/|PARTNER_URL=http://download.oracle.com/otn-pub/java/jdk/8u191-b12/2787e4a523244c269598db4e85c51e0c/|' oracle-java8-installer.*

    sudo sed -i 's|SHA256SUM_TGZ=.*|SHA256SUM_TGZ="53c29507e2405a7ffdbba627e6d64856089b094867479edc5ede4105c1da0d65"|' oracle-java8-installer.*

    sudo sed -i 's|J_DIR=jdk1.8.0_181|J_DIR=jdk1.8.0_191|' oracle-java8-installer.*

    And then finally:

    sudo apt-get -y install oracle-java8-installer

    Hope this helps you :)

  2. I already fixed the error, I already had the latest java version by opening the Java.deb file with a package installer instead of installing java by terminal.
