I was following sudo apt-get update to add the java 8 repo to apt-get

$ sudo add-apt-repository ppa:webupd8team/java

Again update the apt-get repo

$ sudo apt-get update

Finally install java 8

$ sudo apt-get install oracle-java8-installer

but I had a lot of errors, so I fixed and reinstalled them, but now it shows this image:

ho@jhost:~$ sudo apt-get install oracle-java8-installer

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 0 not upgraded.

so I want to know java version is 8

ho@jhost:~$ java -version

java version "1.5.0"

gij (GNU libgcj) version 4.8.4

I need a solution to install oracle-java8

You can select the system wide java default executable via update-alternatives. Run the update-alternatives command with --list option to see the currently installed alternatives:

$ update-alternatives --list java

/usr/lib/jvm/java-11-openjdk-amd64/bin/java

...

Than change the default to your required java version with:

$ sudo update-alternatives --config java

and follow the instruction on the screen.

Thanks all

I solved my problem

I notice to this part

No /var/cache/oracle-jdk8-installer/wgetrc file found.

Creating /var/cache/oracle-jdk8-installer/wgetrc and

using default oracle-java8-installer wgetrc settings for it.

download failed

Oracle JDK 8 is NOT installed.

dpkg: error processing package oracle-java8-installer (--configure):

 subprocess installed post-installation script returned error exit status 1

Errors were encountered while processing:

 oracle-java8-installer

E: Sub-process /usr/bin/dpkg returned an error code (1)

ho@jhost:~$ java -version

The program 'java' can be found in the following packages:

 * default-jre

 * gcj-4.8-jre-headless

 * openjdk-7-jre-headless

 * gcj-4.6-jre-headless

 * openjdk-6-jre-headless

Try: sudo apt-get install <selected package>

So I think it have to problem with URL path, java8 release version and sha256.

ho@jhost:~/Downloads$ sha256sum jdk-8u202-linux-x64.tar.gz 

Find sha256 of tar.gz file,

ho@jhost:/var/lib/dpkg/info$ sudo sed -i 's|SHA256SUM_TGZ="53c29507e2405a7ffdbba627e6d64856089b094867479edc5ede4105c1da0d65"|SHA256SUM_TGZ="9a5c32411a6a06e22b69c495b7975034409fa1652d03aeb8eb5b6f59fd4594e0"|' oracle-java8-installer.*

oracle-java8-installer pointed 8u191 version. so changed several things.

ho@jhost:/var/lib/dpkg/info$ sudo sed -i 's|JAVA_VERSION=8u191|JAVA_VERSION=8u202|' oracle-java8-installer.*

ho@jhost:/var/lib/dpkg/info$ sudo sed -i 's|J_DIR=jdk1.8.0_191|J_DIR=jdk1.8.0_202|' oracle-java8-installer.*

And then,

ho@jhost:~/Downloads$ sudo apt-get install oracle-java8-installer

Oracle JDK 8 installed

#####Important########

To set Oracle JDK8 as default, install the "oracle-java8-set-default" package.

E.g.: sudo apt install oracle-java8-set-default

On Ubuntu systems, oracle-java8-set-default is most probably installed

automatically with this package.
