Description

The error commonly occurs when the cl-ea4-testing or other CloudLinux testing repository are enabled.

 

Workaround

  1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
  2. List the enabled testing repositories. 
    [root@server ~]cPs# yum repolist|grep testing
    cl-ea4-testing CloudLinux 8 EasyApache4 - testing
  3. Disable any testing repositories. 
    yum-config-manager --disable $testingrepo
    Please note that "$testingrepo" must be replaced with the name of the testing repository found with the previous command.
  4. Use yum to update the packages. 
    yum update
