Hi,

To diagnose the problem, try running: 'rpm -Va --nofiles --nodigest'.
You probably have corrupted RPMDB, running 'rpm --rebuilddb' might fix
the issue.
The downloaded packages were saved in cache until the next successful
transaction.
You can remove cached packages by executing 'dnf clean packages'.
How can I solve this?
We don't manage the centos repos so I don't know. RHEL uses the leapp
utility for in-place upgrades but that isn't supported in centos:
https://wiki.centos.org/FAQ/CentOS8#Is_there_a_way_to_upgrade_CentOS-7_to_CentOS-8.3F_How_about_leapp.3F
The packages aren't really all that relevant in any case as there is no
"upgrade" when upgrading client packages. It just installs new bits.
There are some important differences between 7 and 8 that could affect
the resulting upgrade, most importantly that 7 uses authconfig to
configure PAM and 8 uses authselect. Even if you managed to install the
new bits, manually use authselect to re-do the PAM config, the result
will be a failure uninstall because authconfig isn't present to restore
the original PAM config.
It is probably easier and safer to unconfigure the IPA client, uninstall
the packages, upgrade, re-install then reconfigure. You can for example
save the current keytab to re-enroll (see the ipa-client-install man page).

Hmm. In this case it's a master that I want to upgrade. I have two
installations (two distinct environments). One environment with three masters,
and one environment with just one master. In the first environment, I guess
your advise would be to disconnect the master, uninstall freeipa, upgrade (or
reinstall) centos, install freeipa (master). That, I can do. However, that
still leaves me with the problem in my second environment.
I stumbled on these notes at forums.centos.org [1]
"There is no 7->8 upgrade. One has to install fresh 8."
"There is no officially supported pathway to upgrade CentOS 7 to 8."
Wow. I can hardly believe what I'm reading.
