Bug#904343: python3-morse-simulator: fails to install with python 3.7 as a supported python version

[Andreas Beckmann]

Package: python3-morse-simulator
Version: 1.4-3
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts
Control: block 902788 with -1 

Hi,

during a test with piuparts I noticed your package failed to install. As
per definition of the release team this makes the package too buggy for
a release, thus the severity.

>From the attached log (scroll to the bottom...):

  Setting up python3-morse-simulator (1.4-3) ...
    File "/usr/lib/python3/dist-packages/morse/core/request_manager.py", line 140
      def register_service(self, component_name, callback, service_name = None, async = False):
                                                                                    ^

    File "/usr/lib/python3/dist-packages/morse/middleware/ros_request_manager.py", line 396
      return services.service(fn, component = None, name = name, async = True)
                                                                     ^
  SyntaxError: invalid syntax

  dpkg: error processing package python3-morse-simulator (--configure):
   installed python3-morse-simulator package post-installation script subprocess returned error exit status 1


"async" has become a reserved keyword in python 3.7


cheers,

Andreas
