The following packages have unmet dependencies: python-rosdep

edit

I am trying to install ROS Indigo on Ubuntu 14.04 on a Parallels VM. I am running into the following error:

Parallels-Virtual-Platform:~$ sudo apt-get install ros-indigo-desktop-full
Reading package lists... Done
Building dependency tree       
Reading state information... Done
ros-indigo-desktop-full is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 python-rosdep : Depends: python-rosdistro (>= 0.4.0) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I have tried: sudo apt-get update and sudo apt-get upgrade dpkg With the second command, I get the following output in terminal:

Parallels-Virtual-Platform:~$ sudo apt-get upgrade dpkg
