debian8 preseed installation not working

Hi everybody,

right now i am not able to install debian8 via pressed automatic
installation.
It always stucks at the jessie-updates part and says that i will outcommend
it. I have to continue this task manuelly.

Is there a way to say pressed.cfg that it should not write the
jessie-updates source into /etc/apt/sources.list? Cause yesterday there was
a big newsletter with the fact that jessie-updates is not longer working.

Would be great if somebody can tell me how i can add this to my
preseed.cfg, so i have not longer to interact manuelly.

Thanks a lot!
