[SOLVED] How to update Java on Raspbian

Thu Jan 17, 2019 7:32 am

So I've tried about every guide I could find online, and they all end up going nowhere. They all seem to use the "webupd8team" method.

This really shouldn't be this hard. Is there some easier way to get this done, or is that just not something that can be done on the Raspberry Pi 3B+?

I'm open to any suggestions. Been at this for just over 4 hours, and I'm getting nowhere.

Can't remember where I got this from on google, but this worked (for jdk-8u192) - change version number accordingly:
Download the JDK directly from Oracle’s website. Since Raspberry Pi is powered by ARM processor and Raspbian is a 32-bit OS, choose the Linux ARM 32 Hard Float ABI version.
When you have downloaded the right package, unpack it into /usr/java directory:
sudo mkdir /usr/java
cd /usr/java
sudo tar xf ~/jdk-8u111-linux-arm32-vfp-hflt.tar.gz
You can then create symbolic links in /usr/bin folder (so you’ll be able to use java command anywhere) by adding the following alternatives:
sudo update-alternatives --install /usr/bin/java java /usr/java/jdk1.8.0_111/bin/java 1000
sudo update-alternatives --install /usr/bin/javac javac /usr/java/jdk1.8.0_111/bin/javac 1000
At this point, you should be able to verify that your Java installation works by running the following command:
java -version.

That's perfect! I never found a method like this, although I suspected it was something that was straight forward. Just seemed that EVERYBODY had trouble with it, hence why webupd8team stepped in. Here is the command list I used to get up and running on 8u202:

Code: Select all

    sudo mkdir /usr/java
    cd /usr/java
    sudo tar xf ~/jdk-8u202-linux-arm32-vfp-hflt.tar.gz

    sudo update-alternatives --install /usr/bin/java java /usr/java/jdk1.8.0_202/bin/java 1000
    sudo update-alternatives --install /usr/bin/javac javac /usr/java/jdk1.8.0_202/bin/javac 1000

    java -version ; javac -version

Code: Select all

java version "1.8.0_202"
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)
Java HotSpot(TM) Client VM (build 25.202-b08, mixed mode)
javac 1.8.0_202

Hey, I installed Raspbian using NOOBS Lite, does it already have java 8? :?
If not, how can I install it? I need it badly for a project. :geek:

Which version of raspbian did you get? Oracle Java 7 and 8 have been dropped in Buster in favour of openJDK 11 (nice one).

I'm not sure, just the Raspbian recommended by NOOBS. :shock:
But how can I install and older version? 8-)

Ok latest NOOBS will be Raspbian “Buster”.
Does the download java from Oracle as per instructions above work for you?
