As in my link above, I don't think any of the repositories have the latest update. So you will not get the latest "Smaemo6". AFAIK original maemo.org repository is working for downloads but the maintainer can't upload the latest versions. If you can't get the last update with the mirror then you will have to remove the mirrors and wait for the update to be pushed through. I updated to Smaemo6 before all the infra move and mirrors.
