Failed to download package when using bib to build anaconda-iso on centos-stream9

[yih-redhat]

bootc-image-builder failed to build anaconda-iso image on centos-stream9 because it failed to download packages with returned error 503, rerun test cannot resolve this issue. I didn't see this issue when run same test on other OS like Fedora41, Centos-stream10, RHEL9.6 and RHEL10.0.

Here is the log link:

This looks like a temporary mirror issue...I was able to successfully retrieve some of the RPMs that were returned HTTP 503.

I would be curious if we re-ran the CI again tomorrow, would the same error show up.

Can you please also try to pass the --use-librep=true flag? We want to make it default once we get confirmation from QE (c.f. #835) and it should make things (a lot) more robust.

Hi @mvo5 "--use-librepo=true" works, bib can build anaconda iso image successfully.
