Unity 3d installation error

Question

I am using Ubuntu 17.04 and I am trying to install unity 3d on it but after finishing the process it's not in Applicatons. I search for it but I can't find it.

I also tried with GDEBI Package Installer but it show error Dependency is not satisfiable: libpng 12-0

Answer 1

Ok first: The reason why it didn't appear in the applications is that it hasn't been installed ... see the line of your output where it says

"The following packages will be REMOVED: unity-editor "

As explained in Installing Unity3d on Ubuntu 16.04 dpkg does not handle dependencies. If possible try gdebi or some dpendecie resolving installer.

If apt-get install -f does not work maybe try a newer version of Unity?

5.1 is kind of old

use e.g. https://forum.unity3d.com/threads/unity-on-linux-release-notes-and-known-issues.350256/ (at the bottom of the page)

The following steps worked fine for me on a new clean Ubuntu 17.04. install

1. Get the .deb file

https://forum.unity3d.com/threads/unity-on-linux-release-notes-and-known-issues.350256/ (newest version is found at the total bottom of the page)

2. Install gdebi

sudo apt-get install gdebi

3. Install unity using gdebi

sudo gdebi unity-editor_amd64-5.5.3xf1Linux.deb

gdebi should now resolve the dependecies and show you which packages will be installed.

-> type 'y' + ENTER to install

"Unpacking unity-editor ()" can take a couple of minutes to finish so just be patient.

4. start Unity3d

Since most Desktops (I don't know which you are using) have a search function just search for "Unity". It should appear like here

5. LogIn

After the splash appears

You will be asked to LogIn with you account data or to create one.

And respond the following question with I aggree ;)

6. fix License-Error

It might happen (for me it did) that there is an Licence-Error coming up. Here click on "Re-Activate" on the right

And .. you will be asked once again to agrree

After this you have to choose your License Type (For example personal ;) )

And (though we said personal) responde the following (e.g. like this) (Please be honest with this because developers of software also have to live from something ;) )

After finishing this step you should see this screen

7. Use Unity

Create a new Project according to your needs and open it up.

DONE :) You now should be able to use Unity on Ubuntu.
