Installing Unity3d on Ubuntu 16.04

16.04

According to this blog post I should be able to install the .deb version of the Unity Editor for Ubuntu. I have the recommended system requirements. But when I try to install the .deb file using the sudo dpkg -i mydebfile.deb I get the following errors:

Selecting previously unselected package unity-editor.

Has anybody successfully installed the Unity3d on Ubuntu 16.04 yet? Please help if you can.

EDIT: I've been asked if the question How do I install a .deb file via the command line? has solved my problem. The answer is: No, it hasn't. The answers in that question might help one learn how to fix broken dependencies using sudo apt-get -f install but that didn't solve my problem. I had to install each of the missing packages one by one (see comments below). So, I think people coming here for the same problem won't be able to know that they have to install the packages by hand if the question is marked as a duplicate.

Solution 1:

Download

Unity is providing official support for Ubuntu

You can always get the latest releases of Unity3D:

Unity on Linux: Release Notes and Known Issues

scroll down the page for the latest release.

Install

How do I install a .deb file via the command line?

Solution 2:

The dpkg -i command does not resolve dependencies and pull them from apt repositories. You need to install the package using the Ubuntu Software application, or you will need to apt-get install the listed dependencies by hand in a terminal, so that they will be installed and the dependencies for the unity-editor.deb file satisfied.

Solution 3:

Use gdebi! install this gdebi on Ubuntu software, and open file manaager, go to Download, and open terminal on Download. and run:

1.gdebi [.deb file you downloaded.deb(full name)] and wait...

type y when you see [y/n].
try to open Unity editor!

But there is one error I found: If you login, it always shows 'Service not available, please try again later.' Don't try to wait. it ALWAYS shows me.
