Hello,

Unfortunately your package "cuba" was rejected because of the following
reason:

Your upload does not contain a valid signature. Output was:

gpg: Signature made Di 07 Jul 2015 21:19:42 UTC using RSA key ID 8010171C
gpg: Can't check signature: public key not found


Please try to fix it and re-upload. Thanks,
