Whenever I try to build my lighting it always result in crashing of the Unreal Engine.
I have Ubuntu 18.04
Intel i3: 3.9 Ghz

Here’s my crash logs:

Any help is appreciated.
Thanks 
Most likely your PC specs are too low
But I have Windows 10 before with same PC specifications, I did not encounter any issues like this.
Is this may caused by something else?
