Installer crash; problem can't be reported

Hi, 

I bought a new dell latitude 3470 with only ubuntu preloaded. When I start the laptop, it automatically starts the installation process. But the installation crashes in between and it says it will allow me to file a bug report after closing that window. Then the information is being collected. But that stops in the middle and a window appears which says, "The problem can't be reported. This is not an official ubuntu package. Please remove any third party package and try again". Please tell me what to do about this.

Specs of my laptop:

Intel core i7-6500U, NVIDIA GeForce 920M Discrete Graphics

Thanks in advance
