私はfedora 20を実行しsvn checkout svn+ssh://repoていますが、実行しようとすると、キーにsshパスフレーズを入力した後にこのエラーが発生します：
ssh_askpass: exec(/usr/lib64/misc/ssh-askpass): No such file or directory
Host key verification failed.
yumを使用してopenssh-askpassをインストールしましたが、ファイルは作成されませんでした/usr/lib64/misc/ssh-askpass。何が間違っているのでしょうか？
私の.subversion/configファイル：
[tunnels]
ssh = $SVN_SSH ssh -q -p 9001
.bashrc内：
export SVN_SSH="ssh -AT server ssh -T";
出力を詳細に設定すると、次のようになります。（サーバーのURLが変更されました）
