Проблемы с Yum Repo

Моя CentOS-База.РЕПО имеет следующие зеркала:

[base]
name=CentOS-$releasever - Base
baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
enabled=1

#released updates
[updates]
name=CentOS Server updates
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
baseurl=http://custom-url/centOS-updates/
enabled=1

когда я говорю yum install yum-utils, он выдает ошибку, говоря

http://custom-url/centOS-updates/Packages/yum-utils-1.1.31-46.el7_5.noarch.rpm: [Errno 14] HTTP Error 500 - Internal Server Error
Trying other mirror.
Error downloading packages:
yum-utils-1.1.31-46.el7_5.noarch: [Errno 256] No more mirrors to try.

у меня тут два вопроса:

• Why is it looking at the `updates` repo instead of base. `yum info yum-utils` has the repo field set to `updates`. When I disable the `updates` repo in the repo file and do a `yum info yum-utils` it shows the repo field as `base` correctly. What decides the repo to look at given a package?
• Why is 'Package' appended to the baseUrl when it tries to find yum-utils in the updates repo? This is causing a `500 Internal Server Error` as the path with Packages appended to it is invalid
