Alright, now that I have a fix in place, let me explain what's going on.

There have been some issues with syncing MariaDB packages to mirrors due to a bottleneck with our main mirror. This has caused many mirrors to not be fully synced as quickly as it usually happens.

The downloads website checks for the presence of the "repo" or "yum" folder in the mirrors filelist, before it suggests a mirror. The problem is that mirrors now do have those folders but are missing the actual files. I've updated our website to suggest only mirrors that have some files, but the heuristic it uses is not perfect. There may still be missing packages in the mirrors suggested.

This whole problem will go away on its own in a few days as mirrors pick up all the files. For now I hope the fix will make it such that the download page suggests mostly fully synced mirrors. We'll work on a fix so we are less likely to hit this problem with future releases.

Sorry for problematic download experience and thank you for the timely problem reports.
