rosdep update is requested repeatedly

edit

Hi,

I followed the tutorial Installing on Raspberry PI/Raspbian from source and have a problem at point 5.6. When I try the command "sudo rosdep check --from-paths src --ignore-src --rosdistro groovy" I get the error "ERROR: your rosdep installation has not been initialized yet. Please run: rosdep update". The command "rosdep update" has no effect and error message comes again. I run "sudo rosdep init" before.

Thanks for help.

UPDATE 1:

rosdep update

Hit https://github.com/ros/rosdistro/raw/master/rosdep/osx-homebrew.yaml
Hit https://github.com/ros/rosdistro/raw/master/rosdep/base.yaml

Query rosdistro index https://raw.github.com/ros/rosdistro/master/index.yaml
Add distro "groovy"
Add distro "hydro"
Add distro "indigo"
updated cache in /root/.ros/rosdep/sources.cache

With the sudo command (sudo rosdep update) it works and I could run after some fixes in the file "gbpdistro_support.py" the following command:

sudo rosdep check --from-paths src --ignore-src --rosdistro groovy --os=debian:wheezy

but got another problem:

I have built and installed the collada package successfully how it was described in point 5.5.

UPDATE 2:

The result is not much different.

sudo rosdep install --from-paths src --ignore-src --rosdistro groovy -yr --os=debian:wheezy

executing command [sudo apt-get install -y ros-groovy-urdf]
