What does that mean: packages excluded due to repository priority protections

Question

When updating with yum i recieve the following message:

yum update
Loaded plugins: fastestmirror, priorities
Loading mirror speeds from cached hostfile
 * atomic: www7.atomicorp.com
 * base: mirror.de.leaseweb.net
 * extras: mirror.de.leaseweb.net
 * updates: mirror.de.leaseweb.net
118 packages excluded due to repository priority protections
Setting up Update Process
No Packages marked for Update

What does that mean ? How to install these packages ?

Answer 1

Some packages are held by more than one repository. The priorities plugin choose packages from the highest-priority repository, excluding duplicate entries from other repos.
