There are errors in the configuration of this machine. Please fix
the following errors and try again:

Answer 1

So in my case I was using cygwin with windows, and I received:

* `private_key_path` file must exist: 
C:\cygwin64\home\basic.user/.vagrant.d/insecure_private_key

After a few minutes of investigation I realized the VAGRANT_HOME environment variable was not ok, so exporting the right environment variable did the job:

VAGRANT_HOME=/cygdrive/c/Users/basic.user
export VAGRANT_HOME

Answer 2

insecure_key should be a file containing an SSH key. The file should be in the same folder where you vagrant up. The following is an alternative:

curl -o insecure_key -fSL https://github.com/phusion/baseimage-docker/raw/master/image/insecure_key chmod 600 insecure_key vagrant ssh
