@marcoag @clalancette this needs to be checked.

seems lifecycle_py package is missing.

root@51cdd59e1f3e:~# ros2 run lifecycle_py lifecycle_talker
Package 'lifecycle_py' not found
root@51cdd59e1f3e:~# apt-cache search lifecycle_py
root@51cdd59e1f3e:~#

@marcoag @clalancette this needs to be checked.

seems lifecycle_py package is missing.

So the issue here is that lifecycle_py isn't part of ros-jazzy-desktop, which is why it isn't available. I have to take a look to see if that was the case in earlier versions as well, or if we should just update the test-case here to say to install that package first.

[clalancette]

root@51cdd59e1f3e:~# apt-cache search lifecycle_py

By the way, this didn't work because it would need to be:

# apt-cache search '.*lifecycle-py.*'

Can you confirm that returns at least ros-jazzy-lifecycle-py? Also, can you confirm that after installing the package that this test case works?

[fujitatomoya]

@clalancette ah, okay that is lifecycle-py not lifecycle_py (underscore).

root@51cdd59e1f3e:~# apt-cache search lifecycle-py
ros-jazzy-lifecycle-py - Package containing demos for rclpy lifecycle implementation
ros-rolling-lifecycle-py - Package containing demos for rclpy lifecycle implementation

then, after installation, that works without problem.
