How can I suppress sigint-timeout and sigterm-timout options from roslaunch ?

This question is part of a larger problem. I am trying to run a distributed application. I have upgraded one machine to Lubuntu 20.04/Noetic. The other remains as Lubuntu 16.04/Kinetic. My launch file now fails because the options --sigint-timeout and --sigterm-timeout are added to the command line invocation of roslaunch on the remote machine (running Kinetic). Unfortunately that version does not support these options.

roslaunch midget midget.launch 
... logging to /home/paul/.ros/log/989c153c-7864-11eb-bacf-1ff0df2d0d79/roslaunch-clio-11461.log

remote[thalia-0]: Usage: roslaunch [options] [package] <filename> [arg_name:=value...]
       roslaunch [options] <filename> [<filename>...] [arg_name:=value...]

If <filename> is a single dash ('-'), launch XML is read from standard input.

roslaunch: error: no such option: --sigint-timeout

[thalia-0] killing on exit
RLException: remote roslaunch failed to launch: thalia
The traceback for the exception was written to the log file

Is there any way to suppress these command line arguments ? Is there any chance of ROS Noetic co-operating with ROS Kinetic ?

Installing Noetic on the second machine is not really a option - it would require changing the O/S, ROS and a ton of other installed software.

I have this exact same issue. Have you found a solution yet?

@cwillia109 I have given up ! AFAIK different ROS versions never guaranteed to be compatible -- but they normally were as long as there are no changes in message structure. I upgraded my workstation to Ubuntu 20.04/Noetic and now I am forced to change OS and ROS versions on all connected robots. I wish there was a way to avoid that.

You can edit inside the installed ros package and remove the arguments, i.e.

sudo nano /opt/ros/noetic/lib/python3/dist-packages/roslaunch/

And change lines 141 and 142 from

    args = [machine.env_loader, 'roslaunch', '-c', name, '-u', server_uri, '--run_id', run_id,
            '--sigint-timeout', str(sigint_timeout), '--sigterm-timeout', str(sigterm_timeout)]


    args = [machine.env_loader, 'roslaunch', '-c', name, '-u', server_uri, '--run_id', run_id]

Note: You may need to do it every time after apt-upgrading ROS packages
