Debian 11 (Bullseye) was released on August 2021, 14, and is available in a variety of desktop environments. In this description, we will install the desktop version of KDE Plasma, using the Calamares installer in the Live version, which offers a convenient, clean and simplified installation process. This installation is performed on a 64-bit UEFI machine where the Debian 11 (Bullseye) operating system is mounted on a hard disk with a GPT partitioning scheme.
