Package configuration

 +-----------------------+ Configuring locales +-----------------------+
 | Locales are a framework to switch between multiple languages and    |
 | allow users to use their language, country, characters, collation   |
 | order, etc.                                                         |
 |                                                                     |
 | Please choose which locales to generate. UTF-8 locales should be    |
 | chosen by default, particularly for new installations. Other        |
 | character sets may be useful for backwards compatibility with       |
 | older systems and software.                                         |
 |                                                                     |

 +---------------------------------------------------------------------+

 +-----------------------+ Configuring locales +-----------------------+
 | Many packages in Debian use locales to display text in the correct  |
 | language for the user. You can choose a default locale for the      |
 | system from the generated locales.                                  |
 |                                                                     |
 | This will select the default language for the entire system. If     |
 | this system is a multi-user system where not all users are able to  |
 | speak the default language, they will experience difficulties.      |
 |                                                                     |
 | Default locale for the system environment:                          |
 |                                                                     |

원격 데스크톱 설치

일반적으로 Linux 서버에는 기본적으로 데스크톱 환경이 설치되어 있지 않습니다. 첫 번째 단계는 X11과 Xrdp의 백엔드 역할을 할 데스크톱 환경을 설치하는 것입니다.

데비안 저장소에서 사용할 수있는 여러 데스크톱 환경 (DE)이 있습니다. 여기에서는 Xfce를 설치할 것입니다. 빠르고 안정적이며 가벼운 데스크톱 환경으로 원격 서버에서 사용하기에 이상적입니다. Gnome과 같은 다른 데스크탑 환경을 선호하는 경우 Xfce 대신 설치할 수 있습니다.
