Found similar issues in other threads but didn't manage to solve as suggested.

I suspect you're using an outdated version of the python-rosdep package. I've bumped your karma so that you can make links - can you link to the tutorial you're following?

Tutorials: http://www.pcduino.com/install-ros-groovy-on-pcduino/ http://learn.linksprite.com/pcduino/ros/install-ros-groovy-on-pcduino/

Command " sudo apt-get install --reinstall python-rosdep" among output lines gives following: . . . Preparing to replace python-rosdep 0.10.18-1 (using .../python-rosdep_0.10.18-1_all.deb) ... . . . Setting up python-rosdep (0.10.18-1) ...

Answer 1

Those instructions look pretty outdated; in particular, they're pointing you to the old ahendrix-mirror repository on package.ros.org, which hasn't been updated in about a year, and has since been moved to packages.namniart.com.

Please update your /etc/apt/sources.list.d/ros-latest.list to:

deb http://packages.namniart.com/repos/ros precise main

This work for me, thank you! In general now I followed an instruction http://wiki.ros.org/groovy/Installation/UbuntuARM The only difference I installed ros-groovy-ros-comm. Now ros-groovy-ros-base cannot be found if I try to install it.

In addition: before run "sudo apt-get update" I commented lines with "http://www.wiimu.com" in a file /etc/apt/sources.list; When started roscore - an error raised "locale::facet::_S_create_c_locale name not valid";this command helped (but not sure if it's correct): sudo locale-gen en_US en_US.UTF-8

Tried to reinstall (on clean system - recreating bootable MMC as copy of NAND). Cannot install ros-groovy-ros-base by "sudo apt-get install ros-groovy-ros-base": "E: Unable to locate package ros-groovy-ros-base"

Comment by ahendrix on 2014-08-04:
Yes - the ros-groovy-ros-base metapackage is missing. I have the build server running again and I'm looking into it.

Comment by ahendrix on 2014-08-04:
Fixed. You should be able to install ros-groovy-ros-base after running an apt-get update.

Now I was able to install ros-groovy-ros-base. Thank you. When run of roscore raised the error I exported LC_ALL=C and added this command to bashrc: echo "export LC_ALL=C" >> ~/.bashrc
