Linux for PenTest


Hello guys,

Couple days ago I bought raspberry pi 3 B+ model. After reading some articles about penetration testing decides to install Kali Linux distribution. Just curious if I choose a good distribution of Linux . Having some issues with it. After finished of installation of Linux I did
Apt-get update // everything was fine
Apt-get upgrade // black screen and I can’t get into Linux any more… just black screen with nothing just a logo on top right corner.
Can you help guys please ? By the way before upgrading OS I tried to run some Apps everything was so slow even Mozilla which was already pre-installed there didn’t work . Only two things was working wireshark and terminal. Linux was downloaded from offensive security page .
