I am trying to install ROS Indigo in ubuntu 14.04.The link for installation is

http://wiki.ros.org/indigo/Installation/Ubuntu

When I give the following install command in my terminal

sudo apt-get install ros-indigo-desktop-full

the output messages i get is

Reading package lists... Done

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
 ros-indigo-desktop-full : Depends: ros-indigo-desktop but it is not going to be installed
                           Depends: ros-indigo-perception but it is not going to be installed
                           Depends: ros-indigo-simulators but it is not going to be installed
                           Depends: ros-indigo-urdf-tutorial but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I tried

apt-get -f install

and got

E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

So I tried with

sudo apt-get -f install

then i get an error

dpkg-deb: error: archive '/var/cache/apt/archives/python-rosdistro-modules_0.7.0-1_all.deb' has premature member 'control.tar.xz' before 'control.tar.gz', giving up

E: Sub-process /usr/bin/dpkg returned an error code (1)

I tried sudo apt-get clean and sudo apt-get autoremove

I also tried several steps which i got from other forums

sudo rm -rf /var/lib/dpkg/updates/*
sudo rm -rf /var/lib/apt/lists/*
sudo rm /var/cache/apt/*.bin
sudo apt-get clean
sudo apt-get autoremove
sudo apt-get update
sudo dpkg --configure -a
sudo apt-get install -f

Nothing worked out.

Anybody have encountered or have an idea on how to solve this problem?

Thanks for the tip. It worked !!! I removed the broken and residual packages using sudo apt-get remove --purge $(sudo d

debug multiple ROS nodes from eclipse Hi All, I want to debug my ROS code in eclipse. I have different nodes from diffe

I have different nodes from different packages and I want to run it from a single shell script. The description is given below:

I have 3 different packages and each package contains 3 different nodes

(sample directory structure)
    package_name1
    |— src
        |— node1_node.cpp
    |— CMakeLists.txt
    |— package.xml

    package_name2
    |— src
        |— node2_node.cpp
    |— CMakeLists.txt
    |— package.xml

    package_name3
    |— src
        |— node3_node.cpp
    |— CMakeLists.txt
    |— package.xml

Each package has 1 executable. Every time I have to go to each executable path and execute. Instead of that I want to write a single script which will run the 3 different executable from 3 packages.

Is there a way to do that?

I tried by running the script:

cd path_to_package_name1/devel/lib/package_name1
./node1_node
cd path_to_package_name2/devel/lib/package_name2
./node2_node
cd path_to_package_name3/devel/lib/package_name3
./node3_node

But it is executing only the first node.How can I execute the 3 nodes together?

Thanks for your answer and suggestion. I found out why it was giving 'package not found' . There was a space in my file

I usually run the executable directly rather than using rosrun. But when I used rosrun the following error occured: 'pac

Hi all, I am trying to send an array of vector<points> from one node to another node as a message. The message contains this array and other message fields as well.

My cpp file has the following array vector:

 Vector<Point> distancePoints[11];

The above array of vector is the one I need to publish and subscribe.

For example, distancePoints[0] contains vector< Point > from distance 1m and so on. Point contains x and y coordinates. Point is an opencv 2D point class.

Is it possible to publish and receive such array of vector using ROS messages? Does anyone have an idea about how it can be done? What will be the structure of message header?

Thank you for your detailed answer. It was really helpful for me. The code compiled and worked perfectly. But I was not
