Hi @Dercy123!
It looks like the bettercap version you are using has not hstshijcak caplet installed (other than the ones you have in the desktop).
I’ll suggest to remove that kali and download and import a new one again, avoid running any upgrade command in kali or bettercap, then the caplet should be in the path mentioned in the lecture.
And please open a new question thread, it will be easier to follow.

Greetings!
Diego
