While attempting to install something with yum, I got this message:
375 packages excluded due to repository priority protections
A quick Google found an answer at
https://serverfault.com/questions/312472/what-does-that-mean-packages-excluded-due-to-repository-priority-protections. The second answer, with the most upvotes, had the most relevant information:
In 2009, the maintainer of yum mentioned that he hoped people would not use priorities. To disable the priorities plugin, edit /etc/yum/pluginconf.d/priorities.conf and set enabled = 0. After this change, next time you run yum update, you should not get any priority protections.
Assuming the initial statement is correct, is there a reason why priorities are enabled?
I installed SME Server 10.0 Alpha 4 on a VM for testing purposes, so I am not worried about any damage disabling this might do, but I am concerned that if someday we use this in a production environment, it might be a concern.
