 Problem: cannot install both kernel-4.18.0-147.3.1.el8_1.x86_64 and kernel-4.18.0-147.3.1.el8_1.x86_64
  - cannot install the best update candidate for package kernel-4.18.0-147.3.1.el8_1.x86_64
  - cannot install the best update candidate for package kernel-4.18.0-80.el8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

This error is only happening, when original CentOS-Base.repo is disabled. 

Maybe a channel configuration issue? The system is described to 1 parent channel (0 packages) and 1 child channel (containing 3 repos, 7226 packages, not kickstartable).

Thanks for your help.

Hello,

It looks like dnf configuration issue. Normally kernel is never updated but installed and dnf keeps 3 latest versions in parallel (the oldest one may be removed).
I'd try to simplify update to a single package, i.e.
        dnf upgrade kernel-4.18.0-147.3.1.el8_1.x86_64
and see what will happen.
