I am seeing the following error on the Pi during Step 8: Install Dependencies:
sudo apt-get install build-essential python3 python3-dev python3-virtualenv python3-numpy python3-picamera python3-pandas python3-rpi.gpio i2c-tools avahi-utils joystick libopenjp2-7-dev libtiff5-dev gfortran libatlas-base-dev libopenblas-dev libhdf5-serial-dev git results in: Err:1 http://raspbian.raspberrypi.org/raspbian buster/main armhf libexpat1-dev armhf 2.2.6-1 404 Not Found [IP: 220.127.116.11 80] E: Failed to fetch http://raspbian.raspberrypi.org/raspbian/pool/main/e/expat/libexpat1-dev_2.2.6-1_armhf.deb 404 Not Found [IP: 18.104.22.168 80] E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? I have tried 'sudo apt-get update' . It says: E: Repository 'http://raspbian.raspberrypi.org/raspbian buster InRelease' changed its 'Suite' value from 'testing' to 'stable' N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details. I have also tried installing the dependencies with --fix-missing and still no joy. Any ideas why this is not working?
