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.

    It's specific to Unity so, not quite a dupe, but I see your point! The answers on this thread are now out of date (no more .deb file), see my answer for instructions.

  • New way of installing Unity. Same link. No file .deb anymore. You'll get an installation assistant file with extension .0b1 this time. Make it executable 'chmod +x name.0b1' and run it.

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.

    I believe that running sudo apt-get install -f after installing a DEB will install the dependencies for it.

    @dobey installing each one of the dependencies by hand sorted out the problem.

    @dobey Why not pasting here command which installs all Unity3D dependencies? I think that it might be useful for others?

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...

  1. type y when you see [y/n].

  2. 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.

The answers on this page are now all slightly out of date. Unity are no longer providing a .deb file. It took me a minute, but go to this thread:

https://forum.unity.com/threads/unity-on-linux-release-notes-and-known-issues.350256/

And navigate to the last page. Click on the link in the very last post (as instructed) and download the executable. After downloading you will need to add execution rights, either do this via the GUI (right click, go to permissions, and check "Allow executing file as program") or from your command line simply run

chmod +x unity-setup-filename

Now you can open the new graphical assisted installer!
