yum update failing with "Header is not complete"

[Masopust Christian]

hello,

i tried to download the latest updates of my FC4 with yum and failed...

error message is as follows:


Reading repository metadata in from local files
Resolving Dependencies
--> Populating transaction set with selected packages. Please wait.
---> Downloading header for kernel-smp-devel to pack into transaction set.
kernel-smp-devel-2.6.13-1 100% |=========================| 4.2 MB    00:03

Trying other mirror.

and this repeates for each mirror it tries...

what could cause this problem?

thanks a lot,
chris
