我試圖改變爲我的辦公室創建的流浪盒。目前，與大多數框一樣，運行vagrant ssh將用戶登錄爲vagrant，但團隊成員不得不使用su - xxadmin切換到我們的主管理員用戶。更改vagrant ssh用戶創建權限錯誤
在我Vagrantfile，我說：config.ssh.username = "xxadmin"，後來我跑的時候vagrant up開始接受普通流浪錯誤：
[default] Configuring and enabling network interfaces...
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
sed -e '/^#VAGRANT-BEGIN/,/^#VAGRANT-END/ d' /etc/network/interfaces > /tmp/vagrant-network-interfaces
Stdout from the command:
Stderr from the command:
sudo: no tty present and no askpass program specified
和運行vagrant halt時：
[default] Attempting graceful shutdown of VM...
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
shutdown -h now
Stdout from the command:
Stderr from the command:
sudo: no tty present and no askpass program specified
這是怎麼回事？爲什麼簡單地更改ssh用戶創建這些錯誤？我如何找到解決方案？
