버전을 삭제하려면 5.7.8다음과 같이 해야 합니다.

dnf remove kernel-ml-5.7.8-1.el8.elrepo.x86_64
dnf remove kernel-ml-core-5.7.8-1.el8.elrepo.x86_64
dnf remove kernel-ml-devel-5.7.8-1.el8.elrepo.x86_64
dnf remove kernel-ml-modules-5.7.8-1.el8.elrepo.x86_64

5.7.8삭제해야 하는 관련 패키지를 빠르게 선택하는 방법:rpm -qa | grep ^kernel | grep 5\.7\.8

[root@centos /]# rpm -qa | grep ^kernel | grep 5\.7\.8
