前提・実現したいこと
ここに質問の内容を詳しく書いてください。
Ruby on railsで個人アプリを制作し、
AWS EC2 に手動でデプロイできるようになり、
自動デプロイさせる最後の確認のため、bundle exec cap production deployを行うとエラーが発生しました。
■■な機能を実装中に以下のエラーメッセージが発生しました。

試したこと
まずMysquelに接続できていないかもとエラーログを確認し、
mariadbに接続し直しました。
その後のbundle exec cap production deployを行うと、
sshでエラーが発生しているとterminalをみて考え、
sshを追加しようと、ssh-add ~/.ssh/hoge.pemを実行してみましたが、
うまくいかず質問させていただきました。
ssh-copy-id を使用して登録しようとしても手動で登録しようとしてもうまくいきませんでした。
秘密鍵はキーペアで作成しているものの、公開鍵はどう設定して良いのかわからない状態で終了しています。

登録されているsshの鍵を確認しようとしましたが、
接続を開くことができませんでした。
個人開発のディレクトリに入って実行もしてみましたが、
同じエラー（Could not open a connection to your authentication agent.）が出てきました。

リモートホスト側に登録するのは公開鍵のほうです。
ssh-addはssh-agentに秘密鍵を登録するコマンドなのでリモートホスト上で使っても意味がありません。
capistranoではYutaro.Uraokaでxx.xxx.xx.xxに対してSSHログインするのに失敗していると思われるので、SSHログインに使おうとしている秘密鍵に対応する公開鍵がYutaro.Uraokaの~/.ssh/authorized_keysに登録されているかを確認してください。
やりかたは色々出てきますがとりあえず一発目に出てきたこれを貼っておきます。
ssh公開鍵認証設定まとめ
単純なところだと、公開鍵の内容をコピーしてauthorized_keysに貼り付けるといいでしょう。
あと、自分の接続元ホストとか接続先IPとかはちゃんと隠しておいてください。
