First time use centos.
How to install centos 7 repos listed at https://centos.pkgs.org/
I would like to install newer version of some applications, such as NetworkManager which by default on my machine is 1.0.6 from pub-base.
Solution
From RedHat System Administrator Guide - 8.5 Configuring Yum and Yum Repositories
The configuration information for yum and related utilities is located at /etc/yum.conf. This file contains one mandatory [main] section, which enables you to set yum options that have global effect, and can also contain one or more [repository] sections, which allow you to set repository-specific options. However, it is recommended to define individual repositories in new or existing .repo files in the /etc/yum.repos.d/ directory. The values you define in individual [repository] sections of the /etc/yum.conf file override values set in the [main] section.
Then give a look at yum update and other yum Commands.
