Hello, I am trying to launch the camera_pose_calibration as in this tutorial since I want to do en extrinsic calibration of my cameras as the rgb and depth images are not well syncronized. So in any point when I try to launch the node I keep getting this error:

Traceback (most recent call last):

ROS path [2]=/home/rb1base/catkin_ws/src
ROS path [3]=/opt/ros/indigo/share
ROS path [4]=/opt/ros/indigo/stacks

I have already installed several packages that contain that "kdl", what am i missing to do?

Cheers

tl;dr The ResourceNotFound error is probably ignorable in this particular case.

I'm skeptical that the OP hitting a dependency not found issue is because the packages s/he tried to use depend on kdl (or the one with newer name). I scanned openni2_launch and camera_pose_calibration but no find.

$ ack-grep -A 1 -B 1 -i kdl .
$ git remote -vv
origin  git@github.com:delftrobotics/camera_pose_calibration (fetch)
origin  git@github.com:delftrobotics/camera_pose_calibration (push)

    1.11.0

This root cause might be irrelevant to the task, and it's in rospkg package. I filed a ticket (which also has a pull request opened for).

The package is outdated and was only supported up through Groovy. It seems the main trouble is that KDL was named differently for Groovy and prior and is now orocos_kdl.

Fortunately for you, @jbohren made a fork and updated it to Hydro and Catkin. I had to make some additional changes to get it to build in Kinetic on Ubuntu 16.04, I believe my changes should also be good for Indigo. You can try my fork here. Since you're on Indigo you need at least these dependencies:

sudo apt install ros-indigo-calibration ros-indigo-orocos-kdl

Obviously if this is kinetic, swap in kinetic for indigo. Make sure you source your workspace's devel/setup.bash before trying to run anything. Hopefully that gets you a little further. I only went as far as getting it to build and do a basic launch but didn't test any of the package functionality.
