cannot upgrade vm to latest mesos + marathon

[tysonnorris]

Trying to update to latest mesos + marathon versions using:
vagrant up
vagrant provision

I always get errors (output below) related to /etc/bash_completion.d/docker.io - is there a different box that may be better, or some other way to upgrade? Currently box is http://downloads.mesosphere.io/playa-mesos/playa_mesos_ubuntu_14.04.box

The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.

A workaround is simply to vagrant ssh into the box and then run sudo apt-get upgrade. This will update Mesos and Marathon packages to the latest.
