A quick tip as the Pi 4 experiences some issues with the micro-SD cards with NOOBS pre-installed.
As trevor9971 very helpfully pointed out in the previous post, to remedy the Pi 4 needs a full upgrade using the below commands.
First, update your system’s package list by entering the following command:
sudo apt update
Next, upgrade all your installed packages to their latest versions with the following command:
sudo apt full-upgrade
full-upgrade is used in preference to a simple
upgrade, as it also picks up any dependency changes that may have been made.
