Problem: vagrant up fails with the error below. I am running vagrant on Windows 7 and the base box is Ubuntu )( files.vagrantup.com/precise32.box ).

how can it be fixed?

    vagrant.bat up

Bringing machine 'default' up with 'virtualbox' provider...
[default] Clearing any previously set forwarded ports...
[default] Clearing any previously set network interfaces...
[default] Available bridged network interfaces:
1) Intel(R) PRO/1000 EB Network Connection with I/O Acceleration
2) Intel(R) PRO/1000 PL Network Connection
Vagrant is attempting to interface with the UI in a way that requires
a TTY. Most actions in Vagrant that require a TTY have configuration
switches to disable this requirement. Please do that or run Vagrant
with TTY.

Process finished with exit code 1

thanks

This worked for me on cygwin:

Or add this to ~/.bashrc:

export VAGRANT_DETECTED_OS=cygwin

Then I got the "Vagrant displays a message that it needs to run some internal upgrades..."

Edit - Oops! Spoke to soon. During its updates, I got Warning: Authentication failure. Retrying... until timeout :P

Edit 2 - I was able to fix it by setting config.ssh.private_key_path to the .vagrant.d/insecure_private_key in my Windows user's home directory.
