CentOS 9流-执行yum更新的错误
提问于 2022-02-15 19:26:26
我是用Ubuntu来的。
只需在我的DEV服务器上安装CentOS，就会立即出现问题，只需进行更新或安装新的软件包。
以下是错误：
sudo yum update

baseos流9-企业Linux 7的BaseOS epel额外包- x86_64附加程序-常见的CentOS流9- Extras包
在运行EL-9时，您将旧的EPEL (和"remi")用于EL-7。
您需要删除epel版本和remi版本，并安装正确的版本。

我想出了办法，从CentOS 7中复制、粘贴并添加了epel，因此它与CentOS 9上现有的epel相冲突。
使用此方法移除旧的回购：
sudo yum remove epel-release-latest-7.noarch.rpm菲伊:显然是埃佩尔-下一个：

更新：
正如其他人所提到的，有一个关于CentOS9：https://docs.fedoraproject.org/en-US/epel/#_centos_流_9上的回复的最新官方指南。
