Vagrant is attempting to interface with the UI in a way that requires a TTY

Question

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 fi

Answer 1

This is caused by Vagrant finding multiple Ethernet interfaces that can be used as public network and Vagrant cannot decide which one to use.

There are 3 options:

1. Deactivate one of the 2 adapters, so that Vagrant can use the other

2. Specify the Ethernet adapter you would like Vagrant to use in the vagrantfile. Like this:

   app.vm.network "public_network", bridge: "Intel(R) PRO/1000 PL Network Connection"
   

3. Running the vagrant executable manually as already described in Al Belsky's answer
