Subject: bug#33165: GNOME keyring SSH agent => sign_and_send_pubkey: signing failed: agent refused operation

On GuixSD running Gnome: the command 'ssh <remote>' results in error
  sign_and_send_pubkey: signing failed: agent refused operation
and then falls back to password authentication.

(Work-around is to manually start the openssh agent 'eval $(ssh-agent)' after which 'ssh <remote>' is successfull. From this I conclude that the key pair used and the .ssh/config entry for <remote> are OK.)
