How much free space needed to install?

I am trying to install the Unity Editor on Linux but I can't due to too little free disk space. The Unity .deb is 1.2GB but apparently it needs more than that as I have 1.9GB free on my / partition and I still can't install it. How much disk space does the Unity Editor take when installed?

 

It takes up a bit over 4.1 GB + your projects. I don't know how much space the dependencies take up, although I'd imagine it's not much.

Edit: It is possible to move Unity to a different drive after it is installed. To do so, make sure Unity is closed, then run these commands in a terminal window:

• mv /opt/Unity/ /where/you/want/Unity
• ln /where/you/want/Unity /opt/Unity (or "ln -s /your/target/directory /opt/unity" (without quotation marks) if it gives you an error)

 

4.1GB? Mine takes up 3.2GB... Or maybe you're talking about 5.3, I'm still on 5.2

 

Never mind I managed to install in other drive using the .sh script. But now when opening Unity the window that appears is black and has nothing on it.

What I get on ~/.config/unity3d/Editor.log is this:
Error: execv(npm): No such file or directory

EDIT: nevermind, I installed npm and now it works!

 

Yea, found out the hard way that npm was required... (Ubuntu Software Center wasn't even telling me! )

 

Hey can i Ask how you install it to the /opt folder in the terminal of ubuntu. What exactly is the one liner? I tried sudo dpkg -i --instdir=/opt/unity3d unity*.deb and it gives me trouble. But oh well I will just stick with the ubuntu software center method by double clicking the deb. Other then that terminal only said I had problem with the deb package, after installing npm and recommends?
