We can't get the robot to run/connect

[Jennak1]

We tried to run roslaunch and got an error, so we went to fix our file and when we tried to do rsync again it wouldn't work. And we tried to build it again but get errors and we can't even use the keyboard controls. We can't move forward with trying to test it.

dts : To report a bug, please also include the contents of /home/jenna/shell-debug-info.txt

Ok. Firstly, verify that you are connected to the duckiebot using dts fleet discover.

Also, make sure to list the command you ran which produced this error

[johnburton0517]

Running fleet discover does verify that the duckiebot is connected. The command that this error comes from is dts duckiebot keyboard_control duck44

[johnburton0517]

the dashboard is down on fleet discover

[Jennak1]

dts devel build -H <duckiebot_name>.local and dts devel run -H <duckiebot_name>.local -s -M --cmd bash gives the error as well

The dashboard randomly says its working now. Problem may be fixed but not sure yet
