Package Management

To use the package manager (apt) on the Demo image, you'll need to change your timezone.

First, you'll need to locate the correct timezone file at /usr/share/zoneinfo. There should be a folder for your country and a file in that folder for the closest city to you.

$ rm -f /etc/localtime
$ ln -sf /usr/share/zoneinfo/<country>/<city> /etc/localtime

For example, if you're in Central Time USA, you'd use the following commands:

$ rm -f /etc/localtime
$ ln -sf /usr/share/zoneinfo/America/Chicago /etc/localtime

Now, you can run sudo apt update and sudo apt upgrade to get your system up to date.
