I just got the following result for a package push:
cppad>fedpkg push
The authenticity of host 'pkgs.fedoraproject.org (38.145.60.17)' can't be
established.
RSA key fingerprint is SHA256:Q12OTyTeOHWlS54dTzy2BNu7wB8UKNf18+7WHIDsORc.
Are you sure you want to continue connecting (yes/no/[fingerprint])?
Did something change recently ?
