Мой Kali Linux не обновляется и не устанавливает приложения

Что-то вроде этого?

#! /bin/bash

read -p 'Username:' name

# read -p 'Password:' pass
unset pass
prompt="Enter Password:"
while IFS= read -p "$prompt" -r -s -n 1 char
do
    if [[ $char == $'\0' ]]
    then
        break
    fi
    prompt='*'
    pass+="$char"
done

echo
echo Confirm Username: $name?
echo "Confirm Password: ${pass//?/*}"
echo Let us start the quiz :P
echo
echo Q1 - Full form of MCQ
echo a - Maximum Capture Quest
echo b - Multiple Choice Question
read -p "Your Answer:" word
if [[ $word == "b" ]]
then
  echo "Correct! V.Good"
else
  echo "Wrong. U Suck"
fi
