"kernel-devel-3.10.0-xxx.el7.x86_64.rpm" 다운그레이드

wget을 사용하여 다운로드 kernel-devel한 후 설치하고 싶었지만 다음을 통해 설치된 것 같습니다 yum.

$ rpm -i kernel-devel-3.10.0-327.el7.x86_64.rpm
warning: kernel-devel-3.10.0-327.el7.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 192a7d7d: NOKEY

    package kernel-devel-3.10.0-693.11.6.el7.x86_64 (which is newer than kernel-devel-3.10.0-327.el7.x86_64) is already installed

그렇다면 다운그레이드하는 방법은 무엇일까요?

편집하다

kernel-devel-uname-r == $(uname -r)특별 버전을 사용해 보았습니다 .

$ sudo yum install "kernel-devel-uname-r == $(uname -r)"

하지만 그것도 실패했습니다.
