我用debian bullseye在我的NAS上安装了一个git服务器2.30.2。
用户为git，主目录为/media/nas/programming/git_repos/，shell为/bin/bash。
主目录及其所有子目录/文件由git:git拥有。
我使用命令ssh-keygen -t ed25519 -C mymail@gmail.com（或第二次尝试ssh-keygen -t rsa -C mymail@gmail.com）创建了一个私钥/公钥。
在Windows PC上，公钥变为/media/nas/programming/git_repos/.ssh/authorized_keys（git:git所有权，400个权限），私钥变为c:/Users/<username>/.ssh/id_ed25519（或第二次尝试时变为c:/Users/<username>/.ssh/id_rsa）。
在/etc/ssh/sshd_config上我有一条线AllowUsers root git ...
现在，使用Git GUI，我正在尝试连接到带有url url = git@10.0.0.2:my_project的远程（比方说fetch）。
最初，它要求密码来解密id_ed25519（或在第二次尝试id_rsa时）。
然后，它会询问git@10.0.0.2的密码，这意味着Git服务器根本不计算.ssh/authorized_keys。
我在这里做错了什么？

更新ssh -Tv git@10.0.0.2没有说那么多：
