Why is Debian 11 chosen for the server installation?

Debian 11 is chosen for the server installation because it provides a stable base for installing Proxmox, which is the virtual machine hosting software that the tutorial focuses on using.

What is the purpose of resetting the server and installing a new system?

The purpose of resetting the server and installing a new system is to ensure that all participants in the tutorial have a common setup, starting from the same baseline, which simplifies the learning process and ensures consistency.

What is the role of the public key in the server setup?

The public key plays a role in the server setup by allowing secure login access via SSH without the need for a password, which is a more secure method of accessing the server, especially when the server is accessed remotely.

Why is it recommended to update and upgrade the system after installing Debian 11?

It is recommended to update and upgrade the system after installing Debian 11 to ensure that all packages are up to date, which includes security patches and the latest software versions, thereby maintaining system stability and security.

What is the significance of setting the hostname and updating the /etc/hosts file?

Setting the hostname and updating the /etc/hosts file is significant for network identification and communication. It allows the server to be identified on the network and ensures that the server can be reached using its hostname instead of relying on DNS for resolution.

How does the tutorial handle the installation of Proxmox VE?

The tutorial handles the installation of Proxmox VE by first adding the Proxmox repository to the package sources, downloading the required GPG key, and then updating the package list before installing Proxmox VE using the apt install command.

What is the purpose of the postfix configuration during the Proxmox VE installation?

The purpose of the postfix configuration during the Proxmox VE installation is to set up the mail server settings. The tutorial suggests configuring it for local only unless there is a specific mail server in the network, which helps in managing mail services for the virtualized environment.
