安装了ubuntu的两台笔记本电脑。
这些系统上用户1的ssh和git配置是相同的设置。
cat /home/user1/.ssh/config
Host system1
Hostname <system1_ip>
User user1
IdentityFile ~/.ssh/id_rsa_common
cat /home/user1/.gitconfig
[user]
email = user1@gmail.com
name = user1
这些系统中的Rsa私钥/公钥也相同
user1@system1:~/.ssh$ ls -al

在system1中创建的git存储库。
user1 @ system2可以正确地执行“git clone”
user1@system2:~/job/test$ git clone ssh://<system1_ip>/home/git_root/mypicture.git
Cloning into 'mypicture'...
warning: You appear to have cloned an empty repository.
Checking connectivity... done.
orion@ubuntu-pavilion:~/job/test$ ls -al mypicture/
total 12
drwxrwxr-x 3 user1 user1 4096 Apr 18 01:38 .
drwxrwxr-x 3 user1 user1 4096 Apr 18 01:38 ..
drwxrwxr-x 7 user1 user1 4096 Apr 18 01:38 .git
user1 @ system1尝试“git clone”
响应是权限被拒绝（公钥）。
user1@system1:~/job/git_test/local/temp$ git clone ssh://<system1_ip>/home/git_root/mypicture.git
Cloning into 'mypicture'...
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
使用此命令进行调试：
GIT_SSH_COMMAND =“ssh -vvv”git clone ssh：//system1_ip/home/git_root/mypicture.git
部分转储显示无法找到私钥：

如何在system1上将user1 @ system1的ssh / git config或someghing else更改为“git clone”此存储库？

我冒昧地猜测，过于宽松的android.proguardKeep=-keep class com.mypackage.ProblemClass { *; } -keep class android.support.v4.** { *; } -keep class android.support.v7.** { *; } -keep public class * extends android.app.Service -keep public class * extends android.content.BroadcastReceiver -keep public class * extends android.app.Activity -keep public class * extends android.preference.Preference -keep public class com.freshdesk.mobihelp.exception.MobihelpComponentNotFoundException -keepclassmembers class * implements android.os.Parcelable { public static final android.os.Parcelable$Creator *; }
正在绊倒你的ssh，试着将其限制为${HOME}/.ssh/config。查看详细输出，它会尝试键的默认名称，而不是0600您指定的名称。
您也可以更正系统二的权限。通常~/.ssh/id_rsa_common为$HOME/.ssh/和0700，密钥以及config和known_hosts为authorized_hosts。
然而，根据可用信息，它只是一个猜测。有一件事让我感到困扰（但可能是* buntu特定的），我的0600会拒绝ssh在您的系统上看到的permbits，但它也会让我知道它在控制台上这样做{ {1}}。
希望这有帮助。

尝试以下方法：
ssh-add
除非您提供要添加的特定密钥，否则将添加默认密钥
ssh-add是一个用于将SSH私钥添加到SSH身份验证代理中以使用SSH实现单点登录的命令。代理进程称为ssh-agent请阅读以下内容，了解如何运行它。
eval $(ssh-agent)
这将启动ssh代理并打印出servive的PID。
ssh-agent是一个帮助程序，用于跟踪用户的身份密钥及其密码。然后，代理可以使用密钥登录其他服务器，而无需用户再次键入密码或密码。

根本原因是user1 @ system1在执行ssh://system1_ip时无法识别git clone。
${HOME}/.ssh/config仅在Host system1而非Host system1_ip
如果user1 @ system1应用ssh://system1
但到目前为止我还不知道为什么user1 @ system2可以指定ssh://system1_ip的密钥。
