hardy list doesn't recognise date

I installed the medibuntu hardy list. as it should be:

$ sudo wget http://medibuntu.org/sources.list.d/hardy.list -0 /etc/apt/sources.list.d/medibuntu.list

After that I need a update i guess:

alex@alex-laptop:~$ sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update

I get this error: it says basically that the date of todat is unknown.

E: Type '--2010-04-30' op regel 1 in bronlijst /etc/apt/sources.list.d/medibuntu.list is onbekend

Nothing to get it update works properly, as update manager tells me the same and shuts down, after asking to report the problem in update manager.

Anyone a nice and handsome solution?
