내가 주로 사용하는 프로그램들이 공식 지원하는 Ubuntu 버전이 22.04LTS여서 설치하였습니다. 서버 설치는 내용을 입력하기 어려워서 생략합니다. /파티션을 100기가로 자동으로 설치하는 것만 제외하고 모든 사항을 추천하는대로 설치하였습니다.

Welcome to Ubuntu 22.04.5 LTS (GNU/Linux 5.15.0-144-generic x86_64)

처음 ssh로 로그인 하면 위와 같은 화면을 볼 수 있다. 

sudo apt-get install update&&dist-upgrade

예전에 사용하던 명령어인데, 시스템이 불안정해질 수 있다고 해서 지금은 사용하지 않는다. 한번인가 패키지가 꼬여서 현재는 aptitude를 사용한다.

sudo apt-get install aptitude -y
sudo apt-get install aptitude -y
