#1

Fresh new CentOS 8.4 install without EPEL repo (as requested)

I followed installation the guide from here:

https://docs.theforeman.org/2.4/Installing_Server_on_Red_Hat/index-katello.html#centos-8

Problem:
2021-06-04 17:42:10 [ERROR ] [configure] Execution of ‘/bin/dnf -d 0 -e 1 -y install katello’ returned 1: Error:

You need to enable the pki-core module to do that. From the top of my head:

dnf module enable pki-core

The alternative is to follow the guide literally and don’t install katello but rather foreman-installer-katello. The installer should then take care of it.

I’ll try with the pki-core module enabled and see how it goes, but I have followed the guide literally, I have installed foreman-installer-katello .

I’ve got the above error when I tried to use foreman-installer --scenario katello

#4

Yes, that was it, it doesn’t matter if you install just katello or foreman-installer-katello, the OS needs pki-core module enabled.

How do I flag someone to modify the docs?

You can create a pull request or at least an issue at GitHub - theforeman/foreman-documentation: Documentation for the Foreman Project and its ecosystem.

I gave this a try myself as I felt the installer ought to be handling this as well. Can you run the following on the log that hit the error?

 grep -r pki-core /var/log/foreman-installer/

That should tell us if it tried to enable it or if some other snag was potentially hit.

#7

Bellow the log, I created another vm from the template I have just to be sure I get the same error.
I found that the template is an upgrade of CentOS 8.4 from 8.3, so not a clean install to 8.4

Just to collect more info I installed a CentOS 8.4 myself and the error doesn’t reproduce, it works as it should. so maybe is something related to upgrade.

Looks like the module should be enabled. Perhaps the problem is that we miss the dependency pki-core -> katello. Since katello pulls in candlepin, it’s needed but we don’t have it explicit.
