Environment

• CloudLinux 9.4
• cPanel

Solution

1. Backup the CloudLinux OS 9 repo:

mv /etc/yum.repos.d/repo.cloudlinux.com_cloudlinux_9_BaseOS_x86_64_os_.repo{,.bak}

2. Clean and recreate yum/dnf cache :

dnf clean all && dnf makecache

The update then goes successfully using `cloudlinux-x86_64-server-9` repo:

~]# yum update
