If you have a 64bit Operating system, I would reccomend checking if java is 32bit, becuase it will produce a similar error if you are using 32bit java to launch the 1.13 snapshots/version.

Wolfie,  I am interested in helping if I can. Could you start by posting your full crash report?

Are you sure you have a 32bit version of Ubuntu in the first place? You may have a 64bit version of Ubuntu, but have a 32bit version of Java. I would not reccomend updating without checking if you actually have a 32bit version Ubuntu.

use "uname -a" to check if you have a 64bit Ubuntu installation or not

Well, installing a 64bit version of Ubuntu on your 64bit machine would be useful. As for doing it without losing your files. You could just backup your files on some external storage, like a flash drive. I'd reccomend looking through your home folder for things you would like to keep. Also make a list of things you would like to install or do after you install your new OS, so you don't forget any software/settings you perfer.

I believe it is the main graphics library Minecraft uses to do graphics stuff like drawing the game. The library has a team of devs. maintaining it. Sadly the devs. that work on the library dropped support for 32bit linux based machines.

I am getting a 404 (not found/missing) on your pastebin. Did you give the wrong link perhaps?

I will be back in around six hours.

Since liblwjgl32 is not going to be supporting 32bit linux machines everyone trying to launch minecraft with 32bit java on linux will be suffering this error.

As for installing the 64bit version of java make sure you first have a 64bit machine and look for amd64 or LinuxX64 for a 64bit version of java. I have to goto work rn so I hope you will be able to find a guide online on how to actually install java.

Good luck.

Down where it says System details if you are running a 64bit machine and java says your machine is a 32bit one then you have 32bit java. Right here: Operating System: Linux (i386) version 4.15.0-23-generic that "i386" effectivley means you have 32bit java installed

I just found out that my version of JRE was 32bit, I changed it to the 64bit version and Minecraft seems to launch. It seems from your crash report that you are also using a 32bit java.

I get the same error at launch in debian stretch running Oracle JRE. Game fails to launch.
