Cannot build silverblue based image due to curl timeout during build

[woprandi]

For several days, I cannot build silverblue-based image due to timeout on fedora's mirrors

Fedora's mirrors correctly resolve locally

Is this still an issue? The repos seem to be working fine now. Does curl -LI 'https://mirrors.fedoraproject.org/metalink?repo=fedora-42&arch=x86_64' work outside the container?

If the mirrors resolve fine outside the container but not inside, it might be a container networking issue.

More generally though, pulling from mirrors is only required for building ISOs. bootc-image-builder downloads RPMs from the repos defined in the base image to build the Anaconda ISO. We're working on removing this requirement in favour of having Anaconda bootc containers, but that's still not fully available yet.

It's been merged in main here #1094 and mentioned in the README, but (I think) we haven't fully documented it yet.

Well I didn't check before but I no longer have any connectivity inside podman container. Kind of regression (maybe related to Fedora 43 ?) so this issue is not related to this project. Sorry

Thanks for the update!

The issue was related to docker installed alongside podman. For anybody with same issue : containers/podman#24486
