Hi All,

I'm trying to build rxtools and turtlesim package (following ROS tutorials '8. Using rxconsole and roslaunch'), but when I try the command

mehrdad@ubuntu:~$ rosdep install rxtools turtlesim </samp></p></blockquote> I get: <blockquote><p><samp>executing command [sudo apt-get install swig-wx] <br>[sudo] password for mehrdad: <br>Reading package lists... Done <br>Building dependency tree <br>Reading state information... Done <br>E: Unable to locate package swig-wx <br>ERROR: the following rosdeps failed to install <br> apt: command [sudo apt-get install swig-wx] failed </samp></p></blockquote> Then, when I try the above command (<samp>sudo apt-get install swig-wx</samp>), I get this error: <blockquote><p><samp>mehrdad@ubuntu:~$ sudo apt-get install swig-wx
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package swig-wx

How do I resolve this?

I found a rosdistro commit related to swig-wx: Added swig-wx rules to base.yaml

But I can't find the package named 'swig-wx' in packages.ubuntu.com.

So I removed the following lines from ~/.ros/rosdep/sources.cache/0a12...(please check that this is a cache of https://github.com/ros/rosdistro/raw/master/rosdep/base.yaml)

  debian: swig-wx
  ubuntu: {lucid: swig-wx, oneiric: swig-wx, precise: swig-wx, quantal: swig-wx}

Then rosdep seems to work well.

This problem is relevant to ubuntu instead of ROS.


sudo apt-get update

first. If this doesn't work, you can reference
