我不确定这个解决方案 https://unix.stackexchange.com/a/600563/400726
谢谢
答案1
检查您当前使用的内核
uname -r
现在运行
dnf remove --oldinstallonly --setopt installonly_limit=1
检查要卸载的内核是否是您想要删除的内核。完成卸载后Grub会自动更新。只需重新启动即可完成。

如果我有兴趣删除5.7.8版本；我需要做类似的事情：
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
5.7.8快速选择需要删除的 相关包的方法：rpm -qa | grep ^kernel | grep 5\.7\.8
[root@centos /]# rpm -qa | grep ^kernel | grep 5\.7\.8
kernel-ml-modules-5.7.8-1.el8.elrepo.x86_64
kernel-ml-core-5.7.8-1.el8.elrepo.x86_64
kernel-ml-devel-5.7.8-1.el8.elrepo.x86_64
kernel-ml-5.7.8-1.el8.elrepo.x86_64
[root@centos /]#
然后dnf remove $(rpm -qa | grep ^kernel | grep 5\.7\.8)将删除我需要的所有内容！
[root@centos /]# dnf remove $(rpm -qa | grep ^kernel | grep 5\.7\.8)
Dependencies resolved.
