Unity crashes when I open a project Linux Ubuntu 16.04.

So, I had been using Unity 5.4.0 on this computer (which runs Linux Ubuntu 16.04) for about a week. I went to download an asset from the asset store, but it said something like: this asset needs Unity 5.6.0 (or something like that) to download.

So I go to the page where you can download Unity for Linux. That's when I realized that there were newer versions for download. So I downloaded the newest version: Unity 2017.2.0b11. Now here's the annoying part: it takes an HOUR to download. I set it up in the terminal using: sudo dpkg -i unity-editor.deb. After like 15 minutes or so, it finally installed.

I opened it and tried to update the projects by opening them and letting Unity do the rest. Then it just crashed. So I tried to just make a new project. It crashed. I tried again to open the new project. It crashed. I did ALL of this like four times (Downloading, Installing, Running, and Crashing), on about 4 different versions.

Then I realized that this was downloading from "beta.unity3d.com/file/path" for all of them. Some of the earlier ones in the list were: "download.unity3d.com/file/path". So I downloaded Unity 5.6.0 form the download (not beta) link. Then I ran it. It crashed every single time.

If I can't figure this out, then I won't be able to use unity very well at all. (Obviously.) If you guys read this and need a log to figure it out, i would be HAPPY to upload that for you. Thanks for reading and thanks for all of your help.
