 You could try using --skip-broken to work around the problem

二、解决思路

根据问题现象文心一言后，根据解释操作后可以啦

这个错误提示表明，在尝试安装bind-utils的过程中遇到了依赖冲突。具体来说，dhclient包依赖于旧版本的libisc-export.so.95和libdns-export.so.100库文件，但你在尝试安装的新版本bind-libs-lite包并未提供这些库文件。
为了解决这个问题，你可以考虑以下方法：

卸载旧版本的dhclient包，并安装新版本的bind-libs-lite包。首先，输入以下命令卸载旧版本的dhclient： bash
sudo yum remove dhclient
然后，再次尝试安装新版本的bind-libs-lite包：

sudo yum install bind-utils
如果你不能卸载旧版本的dhclient包，或者你认为你需要它，那么你也可以尝试找到一个与旧版本bind-libs-lite兼容的新版本dhclient。为此，你可以在网上搜索相关的教程或求助于专业的技术支持人员。
无论选择哪种方法，请确保在操作前备份你的系统数据，以防万一发生意外情况导致数据丢失
