Cannot execute actions - The passed action type is invalid.

[Pankaj2101]

I just got a iRobot Create 3, connected it to Wifi & installed ROS2 galactic on my PC. set the RMW_IMPLEMENTATION=rmw_cyclonedds_cpp
Tested - PC is able to ping robot - ros2 topic list' & 'ros2 action list etc work well showing Create3 items.
Tested ros2 as well by running - ros2 run demo_nodes_cpp talker & ros2 run demo_nodes_py listener in different terminals and they are working well.

However as soon as I execute ros2 action send_goal /undock irobot_create_msgs/action/Undock "{}"
I get the error The passed action type is invalid

I believe the messages package is/are not installed and so tried.

sudo apt-get update
sudo apt-get-install ros-galactic-irobot-create-msgs

but to no avail.

Can someone guide me to simple resolve.

I would suggest to run the following command after installing the irobot create messages package

source /opt/ros/galactic/setup.sh

[Pankaj2101]

Did not work.
[My bad - I should have posted this in issues]

The OS is Ubuntu 20.04 LTS

++ when I install msgs thru
sudo apt-get update
sudo apt-get-install ros-galactic-irobot-create-msgs

I get a lot of warnings like 'W: Target Packages (restricted/binary-amd64/Packages) is configured multiple times in /etc/apt/spirces.list:42 and /etc/apt/sources.list:54'

@Pankaj2101 please post a full log of the output of the following.

sudo apt-get update
sudo apt-get-install ros-galactic-irobot-create-msgs
source /opt/ros/galactic/setup.sh
ros2 action send_goal /undock irobot_create_msgs/action/Undock "{}"

This is the correct procedure, so there has to be something that is failing while you do that.

Is there anywhere that logs are generated? or some directories/files created?

[Pankaj2101]

Worked after i ran the commands individually.
