Hi all

I recently installed Kali Linux 2019.4 on Vbox 6.1 and everything seemed to be ok, till I decided to upgrade my system. When I type apt-get upgrade what's showed off the display is next:

Se encontraron errores al procesar:
E: Sub-process /usr/bin/dpkg returned an error code (1)
Googling my error code I found this: https://bugs.launchpad.net/ubuntu/+s...ey/+bug/655111
So I then typed apt-get remove --purge firmware-b43-installer and it returned:

dpkg: error al limpiar:
 el subproceso instalado paquete firmware-b43-installer script post-installation devolvi? el c?digo de salida de error 123
Se encontraron errores al procesar:
Proceso detenido por haber demasiados errores.
E: Sub-process /usr/bin/dpkg returned an error code (1)
It's apparently the same issue I'm trying to fix but with no success. I cannot also install any program from apt-get install <whatever>.
I've no WiFi problems since I've installed a third party driver: rtl8188eus to use a wireless usb card.

I leave attached what lspci -nn gives me back when typed:
