This appears to be caused by any package that has a Conflicts tag in the spec that has the exact same name configured in Provides. The above curl package provided above does this:

$ curl -o curl-minimal-7.76.1-23.el9_2.2.x86_64.rpm https://cdn-ubi.redhat.com/content/public/ubi/dist/ubi9/9/x86_64/baseos/os/Packages/c/curl-minimal-7.76.1-23.el9_2.2.x86_64.rpm

$ rpm -qp --conflicts curl-minimal-7.76.1-23.el9_2.2.x86_64.rpm
curl

$ rpm -qp --provides curl-minimal-7.76.1-23.el9_2.2.x86_64.rpm
curl = 7.76.1-23.el9_2.2
curl-minimal = 7.76.1-23.el9_2.2
curl-minimal(x86-64) = 7.76.1-23.el9_2.2

And if I make my own package, host it, and then try to reinstall it it fails in the same way. My specfile:

Name:           hello
Version:        0.0.1
Release:        1%{?dist}
Summary:        Hello World

License:        GPL
Source0:        %{name}-%{version}.tar.gz

Requires:       bash
Conflicts:      hello
Provides:       hello

And note that plain dnf or yum (really yum2) have no problems, but microdnf does upon trying to reinstall:

# dnf reinstall /home/rmanes/rpmbuild/RPMS/x86_64/hello-0.0.1-1.el9.x86_64.rpm -y
[...]
Reinstalled:
  hello-0.0.1-1.el9.x86_64

# microdnf reinstall hello -y
[...]
error: Error running transaction: hello conflicts with hello-0.0.1-1.el9.x86_64
hello conflicts with (installed) hello-0.0.1-1.el9.x86_64

Filed as bz2229809 internally for Red Hat.

Works fine with RPM:

# rpm -U --reinstall /root/rpmbuild/RPMS/x86_64/hello-0.0.1-1.el9.x86_64.rpm

Is microdnf using rpmtsAddReinstallElement() here?

Thank you Michal, I think this is the issue.
