我正在尝试从官方gitlab服务器访问存储库。现在，我收到了错误
ssh_dispatch_run_fatal: Connection to 104.210.2.228: no matching cipher found
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
如果我尝试拉，克隆，甚至ssh git@gitlab.com。
我创建了一个新密钥并进行了测试以检查密钥是否存在问题，但同样的错误仍然存在。

似乎我对OpenSSH的版本有一些错误或不同，但我不确定。任何有关正在发生的事情以及如何修复它的指示都将不胜感激。

找不到匹配的密码
表示您的服务器和客户端提供不同的密码。
客户方：
debug2: kex_parse_kexinit: blowfish-cbc,arcfour
服务器端：
debug2: kex_parse_kexinit: chacha20-poly1305@openssh.com,aes128-ctr,aes192-ctr,aes256-ctr,aes128-gcm@openssh.com,aes256-gcm@openssh.com
客户端提议肯定不是默认值，因为它们是不安全的密码（在任何理智的服务器上禁用）。您应该检查/etc/ssh/ssh_config并删除
Ciphers blowfish-cbc,arcfour
或类似的（无论如何以及为何到达那里）。如果您需要遗留密码来连接到旧系统，则始终存在匹配块，您可以使用
Match legacy.hostmane
Ciphers blowfish-cbc,arcfour

在将我的Macbook升级到HighSierra之后尝试与git lab中的远程连接时，我遇到了类似的问题。
无法与xx.xx.xx.xx端口xx协商：无匹配密码 找到。他们的报价：aes256-cbc，aes128-cbc致命：无法读取 远程存储库。
要解决此问题，只需编辑/etc/ssh/ssh_config文件即可添加支持服务器配置的密码。
这可以通过删除前面的#charactor取消注释行# Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc来完成。
由于ssh文件夹具有访问限制，请使用vim编辑器或在桌面等某个位置制作文件的副本并进行更改，然后在/ etc / ssh /文件夹中替换。

您可以将客户端ssh配置为使用服务器上允许的密码之一。一种方法是使用以下方法修改〜/ .ssh / config：
Host gitlab.com
Ciphers aes256-ctc
