Fix 'Unit network.service not found' Error: Network Service Troubleshooting Guide

This error message suggests that the network service is not installed or is not available on your system. You can try reinstalling the network service or checking if it is enabled and running on your system. Here are some steps you can follow:

1. Check the status of the network service by running the following command in the terminal:

   'systemctl status network'

   If the network service is not running, you can start it by running:

   'sudo systemctl start network'

2. If the network service is still not available, try reinstalling it by running:

   'sudo apt-get install network-manager'

   This will install the network manager package, which includes the network service.

3. After installing the network manager, enable it by running:

   'sudo systemctl enable NetworkManager'

   This will ensure that the network service starts automatically on boot.

4. Finally, restart your system to ensure that the changes take effect.

   'sudo reboot'
