[fedora-arm] Source repositories unavailable?

I installed a f12 on a Sheeva Plug and it works fine. Now I wanted to compile a rpm package from source. I enabled all repos in /etc/yum.repos.d/fedora.repo /etc/yum.repos.d/fedora-updates.repo Then [root@fedora-arm yum.repos.d]# yum clean all Cleaning up Everything root@fedora-arm yum.repos.d]# yumdownloader --source mysql-server fedora | 3.4 kB 00:00 fedora/primary_db | 7.5 MB 00:51 http://ftp.linux.org.uk/pub/linux/arm/fedora/pub/fedora/linux/releases/12...: [Errno 14] HTTP Error 404 : http://ftp.linux.org.uk/pub/linux/arm/fedora/pub/fedora/linux/releases/12... Trying other mirror. Cannot retrieve repository metadata (repomd.xml) for repository: fedora-arm-source. Please verify its path and try again Is there another source for the srpms available? Thanks Norbert Wegener
