I updated my gpg keys because I had a 3072 bits RSA key and Debian requires 4096 bits RSA or elliptic curve. The key fingerprint is:
FF7D B951 7CE1 E19B 6EFE 695F E0E5 BAFD 3BBF 70B3
Check my gpg page for details.
So, if you are from Debian community and signing someone else’s keys which they will be using for the purposes of debian, make sure they are using a 4096 bit RSA key or an elliptic curve key.
