how can it be fi

Answer 1

If you are on Windows and are starting Vagrant through MinGW (Git Bash for example) and get this message, try running it once through Windows' default cmd.exe. You are then able to answer the question about your network adapters.

Answer 2

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
