I installed Kinetic using http://wiki.ros.org/kinetic/Installat... on a Ubuntu 16.04 machine and installed Moveit! using http://moveit.ros.org/install/ . When I execute roslaunch moveit_setup_assistant setup_assistant.launch, following instructions here, http://docs.ros.org/kinetic/api/movei... , I get [roslaunch][ERROR] 2017-01-02 11:25:28,199: 'ascii' codec can't decode byte 0x9a in position 3: ordinal not in range(128).

Uname -a information: Precision-5510 4.4.0-57-generic #78-Ubuntu SMP Fri Dec 9 23:50:32 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

The complete log file is below.

Any help in resolving this would be greatly appreciated. Please let me know if more information is needed.

It seems like there's a non-ascii character (probably š) in one of the file names of one of the files on your system, and the python library for dealing with paths and filenames (os.path.isdir) doesn't like that.

I realize that's not very specific, but without modifying roslaunch to add additional debug information, there's not much more I can say.

You can search for files with that character in the file name in /opt/ros with find /opt/ros -name '*š*'. If that doesn't find anything, you can try searching the whole file system: find / -name '*š*' (give this an hour or two to run if you have a large file system, a slow hard drive, or both)

Thanks ahendrix. As it turns out there was a zero length file named ?p?@@ in the //opt/ros/kinetic/lib/moveit_setup_assistant directory. I don't know how it got there as this is a clean installation of Kinetic. But all is well and Setup Assistant runs.

Thanks again,

Mike

I just installed that debian on my system and could not find a similar file. If you are able to track down a fix please contribute to the Github repo, thanks!
