Npm global install fails / fresh ubuntu server installation

Hey there,
i am trying to install bitcore on a fresh installed Ubuntu 15.10 VPS.
But it fails. Here is some log: Pastebin

I reinstalled the VPS and followed the guide on the website.

If tried to install it locally without the global prefix and it worked fine, but i would like to have it globally.
I hope somebody can help me to solve this issue.

Thanks in Advance

Problem solved.
I created a new user named “bitcore” and followed the guide using the newly created user.
