Why am I getting "python:any (>= 2.7.1-0ubuntu2) but it is not installable" on Raspian Wheezy?

I installed Indigo on Raspian Wheezy on the Raspberry Pi using the excellent article http://wiki.ros.org/ROSberryPi/Instal...

The ROS system functions well; but, when I try to install

$ sudo apt-get update $ sudo apt-get install tightvncserver or $ sudo apt-get install vsftpd

I get the following errors

Reading package lists... Done Building dependency tree
Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: python-catkin-pkg : Depends: python:any (>= 2.7.1-0ubuntu2) but it is not installable python-rosdep : Depends: python:any (>= 2.7.1-0ubuntu2) but it is not installable python-rosdistro : Depends: python:any (>= 2.7.1-0ubuntu2) but it is not installable python-rospkg : Depends: python:any (>= 2.7.1-0ubuntu2) but it is not installable E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I’m a relative NOOB to Linux. Is there any guidance?

I found the work-around/bypass in raspberry pi with ROS Indigo ( or any new Release of ROS)

I edited /var/lib/dpkg/status deleting the python:any segments.

I keep bumping my head on this, but can't find "python:any" in the mentioned file... Tried a few variants, but nothing seems to pop up. Thoughts?

Same problem, I cannot find it too

Similar problem. Since it seems that the unmet dependency is the one about python ( Depends: python:any (>= 2.7.1-0ubuntu2) ) I tried checking my version with

python -V

But it responds: Python 2.7.3. So it's higher that 2.7.1. Could it be something about the "-0ubuntu2" part?

I have the same problem. Any workaround??

Me too, anyone figure it out?

This is big issue omho. I seem to be unable to use catkin_make because of this! And yes, I can't find anything like that indicated in the answer.

The answer to this problem is quite simple (ok, it took me two days until I read the complete article http://wiki.ros.org/ROSberryPi/Instal... and found the correct hint):

Just befor section "2.3 Building the catkin Workspace" is a box with the following note:

Note: Rosdep may report that python-rosdep, python-catkin-pkg, python-rospkg, and python-rosdistro failed to install; however, you can ignore this error because they have already been installed with pip.

It tells you to ignore Failed to detect successful installation of ... and not to ignone unmet dependencies and broken packages facepalm

On a brand new Raspian Wheezy I geht this:

The following packages have unmet dependencies:
python-rosdep : Depends: python:any (>= 2.7.1-0ubuntu2) but it is not installable
             Depends: python-catkin-pkg but it is not going to be installed
             Depends: python-rospkg (>= 1.0.34) but it is not going to be installed
             Depends: python-rosdistro (>= 0.4.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
ERROR: the following rosdeps failed to install

The unmet dependencies can't be ignored, right?
