Jack server is not running or cannot be started on ubuntu 20.04

Hello.

I found the python script below that should be able to give a realistic
humanoid voice to chat gpt,converting the text produced by it into a
humanoid voice and using my voice with a mic to talk with it. In short
terms I want to do the same thing that the “amazon echo / Alexa” voice
assistant does,without buying it. This is the video tutorial where I found
it :

https://www.youtube.com/watch?v=8z8Cobsvc9k

and this is the code :

import openai
import speech_recognition as sr
import pyttsx3
import time

# Initialize OpenAI API

openai.api_key = "ciao a tutti"

# Initialize the text to speech engine

engine=pyttsx3.init()

def transcribe_audio_to_test(filename):

    recogizer=sr.Recognizer()

    with sr.AudioFile(filename)as source:

        audio=recogizer.record(source)

    try:

        return recogizer.recognize_google(audio)

    except:

        print("skipping unkown error")

def generate_response(prompt):

    response= openai.completion.create(

        engine="text-davinci-003",

        prompt=prompt,

        max_tokens=4000,

        n=1,

        stop=None,

        temperature=0.5,

    )

    return response ["Choices"][0]["text"]

def speak_text(text):

    engine.say(text)

    engine.runAndWait()

def main():

    while True:

        #Waith for user say "genius"

        print("Say 'Genius' to start recording your question")

        with sr.Microphone() as source:

            recognizer=sr.Recognizer()

            audio=recognizer.listen(source)

            try:

                transcription = recognizer.recognize_google(audio)

                if transcription.lower()=="genius":

                    #record audio

                    filename ="input.wav"

                    print("Say your question")

                    with sr.Microphone() as source:

                        recognizer=sr.recognize()

                        source.pause_threshold=1

audio=recognizer.listen(source,phrase_time_limit=None,timeout=None)

                        with open(filename,"wb")as f:

                            f.write(audio.get_wav_data())

                    #transcript audio to test

                    text=transcribe_audio_to_test(filename)

                    if text:

                        print(f"yuo said {text}")

                        #Generate the response

                        response = generate_response(text)

                        print(f"chat gpt 3 say {response}")

                        #read resopnse using GPT3

                        speak_text(response)

            except Exception as e:

                print("An error ocurred : {}".format(e))

if __name__=="__main__":

    main()

This code needs that some librares are installed before to run it,but I
don't know which libraries are,because the author won't tell that or don't
know. So,I can only guess. Right now I've guessed these ones :

pip install whisper
pip install boto3
pip install pydub
pip install SpeechRecognition
pip install pyttsx3
apt install espeak
pip install pyaudio
apt install python3-pyaudio
apt install jackd qjackctl

Maybe these aren't the only lbraries that it needs. Anyway,until now,I get
these errors that prevents the code from working :

Do you know what could be missing ?
