我有一台 CentOS Stream 8 服务器，其中有一个备份应用程序，需要使用相同版本的内核进行编译gcc。最新内核是：4.18.0-408.el8.x86_64
我gcc在进行更新的过程中不小心更新了，目前是：gcc version 8.5.0 20210514 (Red Hat 8.5.0-15) (GCC)
gcc8.5 显然从 CentOS Stream 9 移植到了 8，这给我带来了问题。
我需要降级gcc到可用的 8.4。当然，当我尝试时，我收到以下错误：
]# dnf install gcc-8.4.1-1.el8.x86_64

我应该删除dnf remove gcc-plugin-annobin和dnf install gcc-8.4.1-1.el8.x86_64 --skip-broken安装吗？安装 8.4 后一切都会顺利吗？还是我应该删除gcc和gcc-plugin-annobin安装我需要的版本？
我只是想小心谨慎，以免发生任何意外。
谢谢。
答案1
我可以通过使用来解决这个问题--allowerasing
]# dnf install gcc-8.4.1-1.el8.x86_64 --allowerasing删除 gcc 8.5 并安装 8.4
