Update error on CloudLinux: Cannot download repodata/repomd.xml: All mirrors were tried

Symptoms

When running updates or attempting to install a new package, you encounter an error similar to the following.

Error: Failed to download metadata for repo 'cloudlinux-x86_64-server-9': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

Description

The error occurs when the configured repository is unreachable. Adding an additional mirror list can address this.

Workaround

1. Open the file "/etc/sysconfig/rhn/up2date" using your favorite editor and ensure the configuration matches the examples below.

   serverURL=https://xmlrpc.cln.cloudlinux.com/XMLRPC
   mirrorURL=https://repo.cloudlinux.com/cloudlinux/mirrorlists/cln-mirrors
   clnServerURL=http://cln.cloudlinux.com/clweb/xmlrpc

2. If you see this line exists in the file, you must either remove it or comment it out to prevent conflicts with the correct mirror URL.

   mirrorURL=file:///etc/mirrorlist

3. To automatically comment out the incorrect mirror URL line, run the following command:

   sed -i '/^mirrorURL=file:\/\/\/etc\/mirrorlist/s/^/#/' /etc/sysconfig/rhn/up2date
