Warning: If you set priority of base repo to 1, and priority of updates
repo (or all others) to 2, then packages in updates repository will be
hidden. that is why it is so important to have same priority on both
base and updates repositories.
Any package name that exists in 2 or more repositories will be hidden
from repositories with higher number / lesser priority (just like those
66 in your case). Example:
httpd.x86_64 => ver. 2.2.15-26.el6.centos in base
httpd.x86_64 => ver 2.2.15-28.el6.centos in updates
httpd.x86_64 => ver. 2.2.15-29.el6.centos in updates
With priority plugin: base=1, updates=2 (or nothing)
2 packages excluded due to repository priority protections
Available:
httpd.x86_64 => ver. 2.2.15-26.el6.centos from base
With priority plugin: base=1, updates=1 (same priority)
0 packages excluded due to repository priority protections
Available:
httpd.x86_64 => ver. 2.2.15-29.el6.centos from updates
