To make sure I understand here: the problem is not with ansible, but with ssh-copy-id, yes? If so, my first question is: can you in fact log into [email protected] manually? Your error looks consistent with you not having the correct password. Per the man page for ssh-copy-id,

ssh-copy-id is a script that uses ssh(1) to log into a remote machine (presumably using a login password, so password authentication should be enabled, unless you’ve done some clever use of multiple identities).
