Minecraft Launcher is not working in Lubuntu 18.04 LTS

Question

I run minecraft.jar through java 8 oracle run time and this is what the launcher gives me:

Bootstrap (v5)
Current time is May 2, 2018 12:13:19 PM
System.getProperty('os.name') == 'Linux'
System.getProperty('os.version') == '4.15.0-20-generic'

System.getProperty('java.version') == '1.8.0_171'
System.getProperty('java.vendor') == 'Oracle Corporation'
System.getProperty('sun.arch.data.model') == '64'

Exception: javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

    at net.minecraft.bootstrap.Bootstrap.execute(Bootstrap.java:95)
    at net.minecraft.bootstrap.Bootstrap.main(Bootstrap.java:381)
...    
Please fix the error and restart.

How should I proceed?

Solution

That is also the error that jumps to me ... The issue is that Ubuntu 18.04 LTS has Java JDK 11, Minecraft can not run that version of Java ...

The best option would be to install the Minecraft Premium Snap Launcher.

First make sure you have snap support installed:

sudo apt-get update
sudo apt-get install snapd

You should log out and back in if this newly installed snapd, because it adds a new shell initialization script that includes the necessary locations in your PATH environment variable. Without that, the snap command will not be found.

sudo snap install minecraft

And the other option would be to return to Ubuntu 16.04 (as long as it is supported), which still comes with Java 8.

When I try sudo snap even after the two first lines given to me by Antonio Duatz it tells me sudo: snap: command not found.

@TylerPluim Just edited answer: you have to install snap first (use all 3 commands)

This was the one working solution for me in all my search!
