I went through all the steps from this manual of how to setup Homestead.
I've got a problem, when I try to run the vagrant box:

mysystem@me:~/Google Drive/Homestead$ vagrant up

Vagrant failed to initialize at a very early stage:



The home directory you specified is not accessible. The home

directory that Vagrant uses must be both readable and writable.



You specified: /home/mysystem/.vagrant.d

I tried putting the Homestead folder in different places of the system. The Google Drive folder is readable/writable - I create files/folders there without the sudo command. Maybe I am not trying to fix the correct thing, I don't know.
This is my Homestead.yaml file:

authorize: ~/Google Drive/Homestead/.ssh/id_rsa.pub



keys:

    - ~/Google Drive/Homestead/.ssh/id_rsa



folders:

    - map: ~/Google Drive/Homestead/workspace

      to: /home/vagrant/Code



sites:

    - map: test.app

      to: /home/vagrant/Code/test/public



variables:

    - key: APP_ENV

      value: local

and the SSH key file that I generated is ~/Google Drive/Homestead/homestead_key.pub
