nice on but doesn't tell me why the md5sum isn't correct... Usually I don't check the sums if it isn't 'critical' stuff or an OS. So after I checked the other sources and files I figured out that ALL md5sums are incorrect but the file-sizes aren't. In that case either the media is corrupted or my local os (Ubunto). The latter one I couldn't explain because its all genuine and updated almost on a daily basis...
Don't know, may be I stick to my debian and let it just be... However, thanks for your efforts. Gee
