After trying a few times to install the authoring tool using vagrant, i'm still getting the same error during installation process:

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

chown `id -u vagrant`:`id -g vagrant` /vagrant

Stdout from the command:

Stderr from the command:

stdin: is not a tty
chown: changing ownership of '/vagrant': Not a directory

Could you please, help me out?
