在ubuntu/bionic6418.04框上有“ubuntu”用户的流浪者ssh

Question

我试图以ubuntu/bionic64盒版本20181024.0.0上的ubuntu用户身份使用以下Vagrant文件：

# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "ubuntu/bionic64"
  config.vm.box_version = "20181024.0.0"
  config.vm.network :private_network, ip: "192.168.24.25"

  config.vm.provider :virtualbox do |vb|
    vb.customize ["modifyvm", :id, "--memory", "256"]
  end

end

在执行vagrant up和vagrant ssh时，我以流浪者用户的身份登录。如果添加这一行：

config.ssh.username = 'ubuntu'

要获得这样的Vagrantfile文件：

# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "ubuntu/bionic64"
  config.vm.box_version = "20181024.0.0"
  config.vm.network :private_network, ip: "192.168.24.25"

  config.ssh.username = "ubuntu"

  config.vm.provider :virtualbox do |vb|
    vb.customize ["modifyvm", :id, "--memory", "256"]
  end

end

运行vagrant up时，我将得到身份验证错误消息：

default: Warning: Authentication failure. Retrying...

我也尝试过添加这一行

config.ssh.insert_key = 'true'

但这也行不通。

我知道，一旦ssh作为ubuntu/xenial64用户切换到vm中，就可以将用户更改为vagrant用户，但我希望这一操作能够自动完成，就像在默认配置中使用20171011.0.0版本的情况一样。

有什么办法解决这个问题吗？

基于https://openedx.atlassian.net/wiki/spaces/OXA/pages/157802739/Vagrant+is+stuck+Authentication+failure.+Retrying的指令。

总之

1. 在Vagrantfile文件中注释config.ssh.username = "ubuntu"
2. vagrant up \设置具有默认游动用户的VM
3. 从命令IdentityFile vagrant ssh-config的结果中获取vagrant ssh-config路径值
4. 生成键ssh-keygen -y -f <!!path-from-IdentityFile!!>，复制此键
5. vagrant ssh \您将在流浪用户下待一段时间
6. sudo -u ubuntu bash \更改用户
7. vim ~/.ssh/authorized_keys，从4中添加键。
8. 退出VM
9. 取消Vagrantfile文件中的config.ssh.username = "ubuntu"注释
10. vagrant reload
11. vagrant ssh \您现在将使用ubuntu用户
