根据错误日志看，很可能默认的目录下的证书不匹配或者不是正常加载。

[bwcx-jzy]

建议使用低版本的 opensh 生成密钥

[plusgua]

本身就是老版本的openssh生产的key。 我试图在/root/.ssh/id_rsa添加，以及提交key都不可以。

生成key的命令是 ssh-keygen -t rsa -C "x@x"

ssh版本： OpenSSH_8.9p1 Ubuntu-3, OpenSSL 3.0.2 15 Mar 2022

[plusgua]

好吧，用低于8.0的就可以了，很奇怪，建议支持下8.0以上的key.

[bwcx-jzy]

好吧，用低于8.0的就可以了，很奇怪，建议支持下8.0以上的key.

后续 jsch 升级后我们也将同步升级
