Simon and others Here's a very simple and hopefully reproducible test-case
Select as your boot ISO: CentOS-8.1.1911-x86_64-dvd1.iso Choose to reclaim all space on the disk Choose 'Minimal Install' as the software selection Connect yourself to the network (I use a wired connection) Don't bother creating a user, just provide your root password. complete the install.
After the reboot, issue as root: yum -y install perl chrony perl-libwww-perl perl-App-cpanminus gcc
When that is complete, issue: yum list installed >nul and you get conflicting requests as follows:
Modular dependency problems:
Problem 1: conflicting requests - nothing provides module(perl:5.26) needed by module perl-App-cpanminus:1.7044:8010020191120175858:a9207fc6-0.x86_64 Problem 2: conflicting requests - nothing provides module(perl:5.26) needed by module perl-YAML:1.24:8010020191114031501:a5949e2e-0.x86_64
This doesn't seem like the expected results from a clean install. No changes were made in the repo files as supplied on the boot disc.
I would agree. I have the same behavior in a Redhat 8 development system, so it's not a problem with the Centos build. I have not added any repositories other then the Redhat codeready-builder-for-rhel-8-x86_64-rpms. I original installed 8.0 and have applied all updates. I did not notice the problem until recently.
