Update system

The /etc/apt/source.list file stores the software source list of the apt command. Before installing the software, you need to update the package list through the apt command.

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

xxxxxxxxxx
sudo apt update

• Upgrade all installed packages to the latest version with the following command:

xxxxxxxxxx
sudo apt full-upgrade

Note: It is recommended to use the full-upgrade option instead of the upgrade option, so that when related dependencies change, the dependent packages will also be updated synchronously.

• After executing the apt full-upgrade command, the driver, kernel files and some system software may be reinstalled. It is recommended that users manually restart the device for the update to take effect. The command is as follows:

sudo reboot
