Setting the time zone

When installing Ubuntu-22.04.5, it is not suggested to specify the time zone (UTC time is set by default). The time zone must be set manually (for the video archive, access calendars, etc. to work correctly), for example:

sudo timedatectl set-timezone Asia/Novosibirsk

Using the city of Novosibirsk as an example: timedatectl list-timezones | grep “Novosibirsk”

Operating system update

Before starting the installation, it is necessary to update the operating system:

sudo apt update && sudo apt upgrade -y
