sorry for the inconvenience, I could verify the signature correctly. My problem was that I deleted all the other iso files from the file, because I thought I don't need them.
Regards

Hi,
I'm trying to verify the GPG signature of the debian-10.7.0 iso.
Both the sha256 and sha512 give me the output of a wrong signature (see attachment, it's german).
