gpg: Can't check signature: No public key | Debian Raspberry Pi Images

I am having some issue verifying the Raspberry Pi image for the RPI 2B of Debian. **Steps followed:** Download Files:

Has Debian changed their GPG keys? Or am I making a mistake verifying them? Cryptography isn't my specialist and I sincerely apologize if any mistakes are being made on my end. Thank you so much for all of your time and energy. I immensely appreciate any support you can provide.
