我正试图在CentOS 8上安装R，它需要openblas-0.3-5.el8，但使用dnf AppStream repo只能给我openblas-0.33-2.el8。有什么办法可以强迫它安装更新的版本吗？提前谢谢，我真的被困在这里了。
[bosr@rth.ad.rothschild.com@usd1sapp101 ~]$ sudo dnf install openblas

如果我尝试安装R，这里是我得到的错误消息：

丢失的软件包位于名为powertools的repo中，该repo在Centos8上默认禁用。您需要启用此回购，然后重试。在我的GCP虚拟机上，我运行了：
sudo yum install epel-release
sudo yum config-manager --set-enabled powertools
sudo yum install R
我使用wget下载了新版本的openblas和openblas线程。然后我可以安装它们，然后安装R。不知道为什么回购没有给我最新版本，但我现在很好。
