Problem Upgrading Kali Linux Persistence USB
 

Hello everyone,
yesterday i downloaded kali linux and installed it on my usb as presistence
i ran the apt-get update command and it downloaded somethings. then i ran the apt-get upgrade -y command and it said that it had to do 902 upgrades so i left it be and it literally took 9 hrs to download and unpack and then it got stuck at one Unpack so i pressed Ctrl + C and it stopped. i shut it down and now when i try to boot it, it give me a black screen with cursor and when i click it on something it goes to the boot text and just shows that.
what is the problem?

sorry for bad english.

try the steps outlined here: https://ubuntuforums.org/showthread....0#post13549190
esp. "dpkg --configure -a".

Thank you for the reply.
but Where should i type this? when i boot up the usb it in persistence mode it gives me a black screen with a cursor. :(

from grub, boot into recovery mode.
might have to hold down shift (after bios messages) to see the grub menu.
