部署旨在作为 Web 服务器运行的 Rocky Linux VM 后，我进行了更新并收到以下消息：

Error:
Problem 1: cannot install the best update candidate for package libidn2-2.2.0-1.el8.x86_64
- nothing provides libunistring.so.0()(64bit) needed by libidn2-2.3.2-1.el7.x86_64
Problem 2: package remi-release-7.9-3.el7.remi.noarch requires epel-release = 7, but none of the providers can be installed
- cannot install both epel-release-8-13.el8.noarch and epel-release-7-14.noarch
- cannot install both epel-release-7-14.noarch and epel-release-8-13.el8.noarch

- cannot install the best update candidate for package epel-release-7-14.noarch
(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
[root@rocky ~]#
我已经安装了 Apache 2.4、PHP 7.4。以及 PHP 8、MariaDB，它们都安装成功并运行正常。但我注意到它们不是最新版本：Apache 是 2.4.37 而不是 2.4.53，PHP 是 7.4.19 而不是 7.4.29。因此我决定使用 进行升级dnf upgrade --refresh -y，但我偶然发现了上述消息。
这里出了什么问题？
答案1

Enterprise Linux 7 的附加软件包 - x86_64 51 kB/s | 31 kB 00:00
您正在尝试使用EL-7Rocky 8 上的存储库，这当然行不通
你必须使用EL-8EPEL 和 Remi 存储库
去除epel 发布和重新发布打包并按照向导说明进行正确的配置。
