• CloudLinux OS 8

Solution

1. To solve this issue, obtain the relevant license data from CLN:

rhn_check

The output should be empty.

If needed (rhn_check may respond with an error related to the server registration), please update your server license key:

/usr/sbin/rhnreg_ks --activationkey=<activation key>

If you have IP based license, use the clnreg_ks command:

/usr/sbin/clnreg_ks --force

2. After that, clean yum cache and do an update: 

yum clean all
yum update

Cause

The issue should be corrected after a successful registration. The error is caused due to your server not having the permissions to connect to the repositories.
