pyros_interfaces_ros fails to build

[tfoote]

The pyros_interfaces_ros package is failing to build. I believe that there's a python dependency that has changed to default to python3 and will need to be pinned to an older version that supports python2 to keep working.

For example: http://build.ros.org/job/Kbin_uX32__pyros_interfaces_ros__ubuntu_xenial_i386__binary/13/

This is the only known regression in Kinetic for the pending sync. https://discourse.ros.org/t/preparing-for-kinetic-sync-2020-08-20/16002

If it's not resolved we will remove it before the sync next week.

Hi Tully, Thanks for letting me know. It seems more-itertools does not support python2 since version 6.0.0. However I have yet to find which package in the chain includes it as its dependency and where (maybe latest pytest being too new for EOL'd python2 ?) Anyway I currently don't have any spare time to fix Python2 issues as this version has been EOL for a while already. So feel free to remove it from the kinetic packages. (There might be others packages depending on it - especially among http://repositories.ros.org/status_page/ros_kinetic_default.html?q=AlexV). I do not know of any other package depending on pyros, at least on kinetic. If any interest arise I can provide some guidance... otherwise I won't look into it in the foreseeable future. Cheers, -- AlexV

Thanks for letting me know you won't have time. I'll pull it from the distro then. ros/rosdistro#26257
