After that when i try to install java 8 . 

Code: (Select All)

Package oracle-java8-installer is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'oracle-java8-installer' has no installation candidate

Anyone have solution for this?

It looks like licensing issues with java 8 have made it impossible to maintain the repos: https://launchpad.net/~webupd8team/+archive/ubuntu/java

If you have to use it you'll need to get a license and download from oracle: https://www.oracle.com/java/technologies...loads.html

I try it and paste License key also a public key. and all looks ok. after it when try to install oracle java8 or 9 i got same error that 
"E: Package 'oracle-java8-installer' has no installation candidate"

Generally on Linux distro you install the openJDK/openJRE and not the oracle ones due to licensing issue.

Check if there is available a recent edition of openJDK available on your distro repository... or you can build openJDK 8 from source, it is not impossible

You can see from the output of $java - version that openjdk 8 is already installed in @sagher 's original post.

As far as I know there isn't a deb package for the oracle version; the only packaged version is an RPM. It can be built from source. https://docs.oracle.com/en/java/javase/1...D0B48C346A

[edit] there is a .deb package https://download.oracle.com/otn-pub/java...64_bin.deb

Installation of the JDK on Linux Platforms (oracle.com)

but i unable to find the installing candidate of this

The second link in my first post will take you to the downloads page. https://www.oracle.com/java/technologies...loads.html

It turns out I was wrong in my previous post about no .deb - closer inspection reveals there is a .deb (I will edit previous post to reflect this) https://download.oracle.com/otn-pub/java...64_bin.deb

I have a gentle Question here. 
Is the license is compulsory even i go for an older version of JAVA? 
Is it any free service for Linux based servers?
I got download this "jdk-15.0.2_linux-x64_bin.deb" and move to /tmp folder but unable to install it.

I don't know of any specific licensing terms but I'm sure you can find them on oracle's website.
I believe you already have the open version (openjdk & openjre) of JAVA which does not require a license.  You can verify this by your output of  $java -version 

Code: (Select All)

root@kvm-xxxxxxxxxxxxxx:~# java -version
openjdk version "1.8.0_275"
OpenJDK Runtime Environment (build 1.8.0_275-8u275-b01-1~deb9u1-b01)
OpenJDK 64-Bit Server VM (build 25.275-b01, mixed mode)

What command are you using to install the .deb, and what is the output?

i download the file. and paste it into /tmp folder . and give this command via ssh

Code: (Select All)

sudo dpkg -i /tmp/jdk-15.0.2_linux-x64_bin.deb

and the output is :

Just in 10sec. is it all done ?
