I am trying to submit several repositories for documentation following this tutorial: http://wiki.ros.org/rosdistro/Tutoria...

The command rosdistro_reformat file://$(pwd)/distribution.yaml fails with the following output:

Traceback (most recent call last):
  File "/usr/bin/rosdistro_reformat", line 66, in <module>
    success = reformat_files(index)
  File "/usr/lib/python2.7/dist-packages/rosdistro/verify.py", line 58, in reformat_files
    return verify_files(index_url, _reformat_files)

    assert data['type'] == Index._type, "Expected file type is '%s', not '%s'" % (Index._type, data['type'])
AssertionError: Expected file type is 'index', not 'distribution'

The error is the same if I rename distribution.yaml to foo.yaml.

I guess I could do the alphabetic sorting manually...

My package uses the $ROS_DISTRO environment variable at configure time for dh_installudev and for differences between Indigo and Kinetic. The buildfarm doesn't seem to define $ROS_DISTRO.

It looks like it's not necessary to know the debian package name. The simple filename udev can be used. https://github.
