Raspberry Pi installs Java 8 using PPA

Objective

Installing Java 8 on a Raspberry Pi is similar to this one, but the Raspberry Pi does not support adding Webupd8team sources automatically with add-apt-repository, so add them manually.

Steps

Create a new webupd8team-java.list in/etc/apt/sources.list.d, add a source

sudo vim.tiny /etc/apt/sources.list.d/webupd8team-java.list

Add content, the Raspberry Pi Raspbian version used here is stretch, to change xenial to stretch, but it seems that the source does not update the corresponding version, so use the old version xenial

deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main

After saving the Apt-get update update, an error occurred "The following signature cannot be verified because there is no public key: No_pubkey c2518248eea14886", so the public key needs to be added

sudo apt-get install dirmngrsudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C2518248EEA14886sudo apt-get update

Then install the Oracle-java8-installer, determine the operation in the process can be

sudo apt-get install oracle-java8-installer

After the installation is complete java-version view version, display

java version "1.8.0_171"Java(TM) SE Runtime Environment (build 1.8.0_171-b11)Java HotSpot(TM) Client VM (build 25.171-b11, mixed mode)
