CentOS - 업데이트 확인

방금 VPS를 구입하고 제공된 템플릿에서 CentOS 7 Minimal을 "설치"했습니다.

설치 후 업데이트를 시도했지만 이 메시지가 표시되었습니다.업데이트 대상으로 표시된 패키지가 없습니다..

# yum update

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: ftpmirror.your.org
 * extras: ftpmirror.your.org
 * updates: ftpmirror.your.org
No packages marked for update

나는 사용해 보았습니다.냠 다 청소해그리고 "유명한"재시작, 그러나 메시지는 항상 동일합니다.

템플릿 이미지가 실제로 업데이트된 것인지, 아니면 제가 뭔가 잘못하고 있는 것인지 궁금합니다. 설치된 패키지를 나열하면 거의 모든 날짜가 2개월 이내입니다(오늘은 2017년 9월 4일 월요일 12:09:58).

이것이 문제입니까(구성 오류) 아니면 템플릿이 실제로 업데이트되었습니까?
