System Update

For system security and stability reasons, it is recommended that users update the system using the apt command after installing the system.

The /etc/apt/source.list file contains the list of software sources for the apt command. Before installing software, you need to update the package list using the apt command.

• First, open the terminal command line and enter the following command:

xxxxxxxxxx
sudo apt update

• Next, upgrade all installed packages to the latest versions using the following command:

xxxxxxxxxx
sudo apt full-upgrade

It is recommended to use the full-upgrade option instead of upgrade so that dependency packages are also updated synchronously when related dependencies change.

• After executing the apt full-upgrade command, drivers, kernel files, and some system software may be reinstalled. It is recommended that users manually reboot the device for the updates to take effect using the following command:

sudo reboot
