Yum 업데이트 확인에 실패했습니다.

오늘 아침부터 yumCentos 7.6에서 패키지 업데이트를 확인할 때 오류가 발생합니다. 내가 실행할 때 :

그럼 EPEL이 마음에 들지 않는 것 같은데 updateinfo... 어떻게 해야 할까요? 이 문제를 어떻게 해결할 수 있나요?

나이것을 찾았다, 하지만 그것이 나에게 어떻게 적용되는지 이해가 안 되나요?

편집하다: 분명히 업데이트가 작동했지만 check-update실패했을 뿐입니다. cron이 check-update매시간 실행되고 받은편지함이 폭발하기 때문에 이것은 번거로운 일입니다. 하지만 여전히 업데이트를 실행할 수 있습니다.

편집 2: 그것어쩌면 나타날지도현재 EPEL에 문제가 있어 크론 작업을 조정해야 합니다.
