这个是调试的详细信息，求大神解答，谢谢

看看服务器的 authorized_keys 文件的权限是不是 644。

[feveryone]

服务端应该没问题，因为服务端是ubuntu core，他通过ubuntu one下载我提供的公钥到自己系统内，然后与我自己的私钥配对，现在我还没有登进ubuntu core系统，无法查看他的authorized_keys是不是权限644。

[幽饮烛]

ssh 没配置免密登陆吧。或者配置的公钥和客户端的私钥不匹配。

[feveryone]

这些都已经设置过了，公钥和私钥是一对，但是已经把文档看烂了还是找不出问题出在哪。从调试信息看，感觉感觉应该是匹配了，但是无法免密登录，ubuntu core系统进不去，也无法对里面进行设置。
