You need to reset the permissions on your `.ssh` directory. Run `chmod 700 /home/user/.ssh` and then `chmod 600 /home/user/.ssh/config`. You may need to repeat this for other files mentioned in the error message.

You may be trying to run Algo with Python3. Algo uses [Ansible](https://github.com/ansible/ansible) which has issues with Python3, although this situation is improving over time. Try running Algo with Python2 to fix this issue. Open your terminal and `cd` to the directory with Algo, then run: ``virtualenv -p `which python2.7` env && source env/bin/activate && pip install -r requirements.txt``
