Minecraft won't open in 14.4

Asked by Niels on 2019-09-11

Basically, whenever I tried to open minecraft before, it was always:
Double click on the icon, click play, the loading bar fills up and it would just open minecraft.
now what I do is double click on the icon, click play, and it doesn't load.
I've tried, other applications to open it, won't open.
When I tried loading the game offline, it gave me this message:

Error: Could not find or load main class net.minecraft.client.main.Main

I'm not comfortable enough with computer code to see what's the problem there, so...
what do I do?

How did you install Minecraft? I assume you mean 14.04... As in the Ubuntu version

If "14.4" is meant to describe Ubuntu release 14.04 - this release is not supported any more (except for paid security maintenance for selected server packages).

You should consider upgrading to a supported Ubuntu release, e.g. Ubuntu 18.04 LTS in due course.

I meant 1.14, sorry, I was not looking at what I was writing.
And it is meant for minecraft itself, I have Ubuntus latest version and everything updated to max, so the problem shouldn't lie there.

I installed minecraft through the website, paid for it, got it set up properly on my computer after almost an hour. It worked fine for a year or so, and then, with the introduce of minecraft 1.14 it started producing problems. At first just system crashes every now and then, until it got so bad that I had 5 crashes within 20 minutes (which is not ideal -_-)
I didn't play for a few weeks and now the game won't start up again. (Some extra backstory that might lead us to the problem)

How did you install minecraft? With the Minecraft.deb file for Debian/Ubuntu on the minecraft.net web page? Or how else?

Try starting it by entering the command
in a terminal window. This might provide additional output.

Yayy, I did it!
I tried the thing with the terminal window, which gave me a reply like: This file doesn't exist.
So, I went back to the minecraft website, where I changed the download option, and it friggin worked.
Thanks man :)
