Docker build failed [insufficient_scope: authorization failed]

I am trying to build an image for a django project. I tried ”’sudo docker login”’, after that also same error message. tried in macOS M1 & rasberrypi 4B.

**Dockerfile:

FROM python3.9.2-slim

ENV PYTHONUNBUFFERED 1

RUN sudo apt update -y && sudo apt upgrade -y

RUN mkdir /app
WORKDIR /app

COPY requirements.txt /app/
RUN pip install --user -r requirements.txt

COPY . /app/

CMD python3 manage.py runserver

Output(sudo docker build . -t ttapp-image):

    Change image from python3.9.2-slim to python:3.9.2-slim.

    Just a couple of suggestions to your dockerfile that may help solve the problem.

    you dont have to specify the complete image name and tag..instead use

    FROM python:3.9-slim

    You also dont need to use sudo inside docker. Docker runs the commands as root user by default unless specified. instead use..

    RUN apt-get update && apt-get upgrade -y
