Why is openjdk-8 not installed well?
I installed openjdk-8-jdk, but at /usr/lib/jvm/java-8-openjdk-amd64, there is only bin, include, lib, man.
Also, /usr/lib/jvm/java-8-openjdk-amd64/bin has just 2 files (appletviewer, jconsole).
So I've removed it and then re-installed it, but it doesn't work.
How do I get Java to install correctly?
Open the terminal and type:
sudo apt update
sudo apt remove openjdk-8-jre openjdk-8-jdk
sudo apt install openjdk-8-jre openjdk-8-jdk
