语境：

  • 首先，我有一个新的 ubuntu 20.04 服务器和密码
  • 我在 Windows 10 上使用 OpenSSH 客户端
  • 我想做无密码登录，那么我
    • 使用密码 ssh 到服务器，
    • 手动创建~/.ssh /authorized_keys并打开它vim
    • 将我的公钥内容从我的C:\users\me\.ssh\id_rsa.pubssh 窗口复制并粘贴。
    • 退出该 ssh 会话并尝试无密码登录，
    • 失败的
  • （更多的尝试和很多的头撞）🤕
  • 我在 Windows 上安装 Git Bash，然后运行并在服务器上ssh-copy-id获得另一条相同的行authorized_keys
  • 现在我可以成功无密码登录服务器

为什么会发生这种情况？ssh-copy-id除了在其中插入一行之外，还可以做更多的事情吗(server) ~/.ssh/authorized_keys？

在此输入图像描述

我需要7z在wsl-ub1804上使用，所以我尝试安装它，sudo apt-get install p7zip-full但它失败了。我检查了ubuntu 包，所以我确定它在那里。

我检查了其他问题，并且我的宇宙回购已启用

如果需要，这是我的控制台日志。

什么是问题，我该如何解决？
