Ubuntu 16.04: Oracle JDK 9 not installed

Question

Every time I try to install something from the terminal, this message appears to me. Meanwhile, I have my Java installed:

download failed Oracle JDK 9 is NOT installed. dpkg: error processing package oracle-java9-installer (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: oracle-java9-installer E: Sub-process /usr/bin/dpkg returned an error code (1) 

Please help me solve this problem; it is really annoying.

Answer 1

 sudo apt-get purge oracle-java9-installer 

solved my problem. Later, I also changed the Ubuntu Software Center Server to the Primary Server.

Answer 2

In fact, I ran into a problem after allowing the installation of wine in my Ubuntu 16.04 LTS . The fault problem that I solved using the link below.

So, landed on this post. But I could not install java from apt packages. It threw me a mistake. Then I realized that there was a problem with multiple Java instances on my system. I already have Oracle Java 9 installed. I just needed to change the current versions using the command

 sudo update-alternatives --config java 

So, if any of the bodies gets into error, you can try to fix this.

I'm not sure what steps you tried to install already, but the link below is a pretty well-explained description of how to install the JDK on Ubuntu. I always installed JDK via webupd8team ppa, and it worked for me so far :)

A note about the link, it suggests setting the home variable, it may be necessary for you, but I never did it manually, and it worked, so give it a quick check before setting the home variable yourself.

Answer 4

I solved the problem by uninstalling all versions of java and cleaning them up and installing them again, perhaps thanks to everyone who tried to help.

Answer 5

Add Oracle PPA first, and then update the package repository.

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

To install JDK 9, use the following command:

 $sudo apt-get install oracle-java9-installer 

Answer 6

To completely remove the Oracle JDK, run the following commands:

Delete criteria completely:

 sudo apt-get remove oracle-java9-installer sudo apt-get remove --auto-remove oracle-java9-installer sudo apt-get purge oracle-java9-installer sudo apt-get purge --auto-remove oracle-java9-installer

After that install jdk using the following command:

Install JDK9 on Ubuntu:

 sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java9-installer 

Make it the default:

 sudo apt-get install oracle-java9-set-default
