ssh-copy-idコマンドを実行すると「Too many authentication failures」がでる

公開鍵を作成してサーバにコピーしようとすると「Too many authentication failures」というエラーが出てコピーできませんでした。

$ ssh-keygen -t ed25519
$ ssh-copy-id -i ~/.ssh/id_ed25519.pub yoshi@192.168.122.22
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/yoshi/.ssh/id_ed25519.pub"

サーバにはsshでパスワード認証でログインできています。

ssh-copy-idコマンドを-o IdentitiesOnly=yesオプションで無事コピーできました。
