答案1
请注意，已安装的软件包具有后缀.el8，但该工具抱怨的许多软件包都具有后缀.el7。
我看到两种可能性。该系统可能被错误配置为连接到 OEL7 存储库而不是 OEL8 存储库，或者存储库服务器混合了 OEL7 和 OEL8 软件包，这意味着存储库已损坏。
你应该先运行rpm -qa |grep '\.el7'。如果您当前安装了任何 OEL7 软件包，则可能会遇到问题：存储库配置中的混淆导致系统的某些部分降级到 OEL7 级别。首先备份您的数据。如果没有报告 OEL7 包裹，那么可以松一口气。
然后签入所有文件/etc/yum.repos.d并删除或禁用任何引用 OEL7 内容的存储库，然后运行yum clean all，然后yum check-update查看它现在将提供的操作。如果事实证明应该包含 OEL8 内容的包存储库实际上混有 OEL7 包，提醒该软件包存储库服务器的管理员修复损坏的存储库，否则您最终可能需要修复更多部分降级的服务器，而不仅仅是一台。
如果安装了任何 OEL7 软件包，软件包管理器现在可能会建议将它们替换为 OEL8 等效项：这将是一件好事。 （基本上我希望任何可能自动降级的东西也能同样轻松地升级。）
如果它仍然抱怨某些事情，您可能有一个 OEL7 包，它在 OEL8 中没有直接替换，并且通过依赖项“锚定”其他 OEL7 包。这可能是由于尝试在 OEL 版本 8 中使用适用于 RHEL/OEL 版本 7.x 的 EPEL 存储库中的软件包造成的。然后，您可能必须找到并手动更新或临时卸载“锚定”软件包，以便所有其他软件包可以取消降级至 OEL8 级别。
如果似乎安装了大量 OEL7 软件包，您可能需要考虑备份数据并从头开始重新安装的核选项。这可能比花时间来理清混乱更容易，而且肯定更快。
