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。

尝试:
yum clean all
yum check
yum check-update
yum update如果仍然存在问题,请尝试:
yum update --nobest

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:

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。
