Software requirements
Should you run into difficulties updating Kali Linux or running Xplico (which happens sometimes), consider downloading and running DEFT Linux 8.2 in a virtual environment. Beginners may find that Xplico may be easier to work with in DEFT Linux as there are GUI menu items to start the Apache and Xplico services options, whereas these have to be typed into the Terminal in Kali Linux.
Important note:
DEFT Linux 8.2 can be downloaded from https://na.mirror.garr.it/mirrors/deft/iso/.
