• The enabled preview channel points to /azurelinux/4/preview, but that endpoint does not currently expose RPM repository metadata; the published AZL 4 preview tree used elsewhere in this repository is /azurelinux/4.0/beta (for example, distro/mock/azl4/stage2/azurelinux-4.0.tpl:92). Since the base section is enabled with skip_if_unavailable=False, this makes normal DNF metadata refreshes fail. Point this at the live preview tree, or ensure the new endpoint is populated before shipping this configuration.

# NOTE: We force-enable preview repos until production repos are fully populated.

• The preview prefix has the same invalid major-only path: PMC publishes Azure Linux 4 repositories beneath /azurelinux/4.0/, not /azurelinux/4/. Since preview base is force-enabled and unavailable repositories are fatal for that section, this also breaks DNF transactions. Use $releasever (or 4.0) in this URL.
