dnf5 update misses --best --allowerasing hint

[Germano0]

On Fedora 40, during a dnf5 update I am currently experiencing a package conflict so the update is not even starting. Instead according to old dnf-4.21.1 the problem can be fixed by using --best --allowerasing, but the new dnf5 did not mention that.
dnf 4 output:

Nothing to do.

And finally I solved the problem by using --best --allowerasing on dnf5

What version of dnf5 do you have?
Can you try to reproduce with newest version? Its available in our nightly copr: https://copr.fedorainfracloud.org/coprs/rpmsoftwaremanagement/dnf-nightly/.

I think this should be already resolved by #1328.

[Germano0]

dnf5-5.1.17-2.fc40
At the moment I don't have the opportunity to reproduce a package conflict to trigger --best --allowerasing hint with latest nightly dnf5

[kontura]

Ok, that version already contains the mentioned commit.

I have created a test that reproduces it: kontura/ci-dnf-stack@635f50a.

This confirms the issue.
