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
How to find out the name of your time zone?
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
