自 Anolis OS 23.1 版本开始，6.6 版本内核为默认内核，os 仓库中默认存放的内核版本从 5.10 变更为 6.6。因此 kernel-6 仓库在 23.1 版本维护期间将维持空仓库状态，如果有 6.6 内核包下载的需求请至 os 仓库中下载。可以参考 https://bugzilla.openanolis.cn/show_bug.cgi?id=9280 获取如何安装 5.10 内核的方法

Since Anolis OS 23.1, kernel-6.6 is set to be the default kernel instead of kernel-5.10, hence we moved kernel-related packages from `kernel-6/` dir to `os/` dir. You can install kernel-6.6 with Yum/DNF directly and it is safe to remove `kernel-6` repo from your repo file; if you need to install kernel-5.10 in Anolis OS 23.1, please refer to https://bugzilla.openanolis.cn/show_bug.cgi?id=9280 to learn how to install related repo file and switch kernel.
