[FIXED] Upgrading from openJDK 8 to openJDK 11

Issue

I have JDK 8 installed in my ubuntu 18.04 system and I now want to upgrade it to JDK 11 using this. I just want to know if this would create any problem or not. Would the older version be removed on upgrading( Actually I want older version to be removed by itself)?

Solution

Do this to uninstall previous versions of openJDK on Ubuntu

sudo apt-get remove openjdk

To remove all of the config files and dependencies.

sudo apt-get purge --auto-remove openjdk*

Then install openJDK 11

sudo apt-get install openjdk-11-jdk
