sudo apt update is a command used in Debian-based Linux distributions to update the package list.  
Our tutorial does not state that you have to execute sudo-get update, but it is crucial that you install picar-4wd without errors?  
Steps for installing picar-4wd:  
cd ~  
git clone [GitHub - sunfounder/picar-4wd](https://github.com/sunfounder/picar-4wd)  
cd ~/picar-4wd  
sudo python3 setup.py install  
After successful installation and starting the Raspberry Pi.  
Go ahead and execute the sample code script again to see if it works.  
What version of Raspberry Pi are you currently using?

The error should be caused by a network anomaly.  
It is recommended that you perform the installation a few more times to see the results.  
It is also recommended that you install an older version of the Raspberry Pi system (legacy), it is the bookworm version of the Raspberry Pi system that is not compatible with the installation of the picar-4wd code.
