我正在运行 fedora 20，当我尝试运行时，svn checkout svn+ssh://repo输入我的密钥的 ssh 密码后出现此错误：
ssh_askpass: exec(/usr/lib64/misc/ssh-askpass): No such file or directory
Host key verification failed.
我已经使用 yum 安装了 openssh-askpass，但它没有创建文件/usr/lib64/misc/ssh-askpass。我可能做错了什么？
我的.subversion/config文件：
[tunnels]
ssh = $SVN_SSH ssh -q -p 9001
在.bashrc中：
export SVN_SSH="ssh -AT server ssh -T";
将我的输出设置为详细，我得到以下内容。（服务器的 URL 已被更改）

答案1
我发现问题出在我的环境变量 SVN_SSH 中。我不明白为什么，但通过将其更改为：
export SVN_SSH="ssh -T";
有效。
