내 RHEL 버전:
[root@x]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.9 (Maipo)
여기 RHEL 7 지침에 따라 EPEL을 활성화했습니다.https://docs.fedoraproject.org/en-US/epel/#How_can_I_use_these_extra_packages.3F
subscription-manager repos --enable rhel-*-optional-rpms \
--enable rhel-*-extras-rpms \
--enable rhel-ha-for-rhel-*-server-rpms
yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
epel을 설치하기 위해 두 번째 명령을 실행하면 다음과 같은 결과가 나타납니다.

여기서 이런 글을 봤습니다:https://access.redhat.com/solutions/4780531
그래서 게시를 설정했습니다.
subscription-manager release --set=7.9
이것이 /7.9/바로 위의 URL에서 볼 수 있는 이유입니다.
저장소를 비활성화했다가 다시 활성화했습니다. 여전히 같은 오류가 발생합니다.
문제가 있는 URL 중 하나에 액세스하려고 하면 다음이 표시됩니다.

이게 왜 깨졌나요? 분명히 URL은 유효하며 직접 액세스하면 404를 제공하는 대신 403을 얻습니다. 그렇다면 왜 403이 직접 접속에 나타난다고 하는 yum걸까요 ?404 - Not Found
내가 원하는 것은 설치 iftop하고 예상대로 작동하기를 바라는 것뿐입니다.
[root@x]# yum install iftop

나는 다음을 실행했다:
subscription-manager repos --disable=rhel-7-server-e4s-optional-rpms
subscription-manager repos --disable=rhel-7-server-eus-optional-rpms
그리고 성공적으로 설치되었습니다 iftop. 이런 것들은 왜 깨지는 걸까요?
