Bug CopyPackageFile failed, unable to copy unityeditor-cloud-hub-0.0.1.tgz

Install:
unity-editor-5.3.1f1+20160106_amd64.deb
Ubuntu 15.04

I get the following error when I first load up Unity3d after my initial install - I've not been able to run it once yet, all I get is some grey screens.

Attempting to diagnose what the issue is. It feels like a permissions issue, but I'm not sure yet.

There is no npm-debug, even though the log says there should be more information in there.

I did a `mkdir -p /home/mark/.local/share/unity3d/Packages/` and it seems to have solved the issue.
