Here are the commands I ran to install and setup my enviroment:

sudo apt-get install ros-humble-system-fingerprint
source /opt/ros/humble/setup.bash

When I run the command in the readme I get this error:

rosrun system_fingerprint imprint

Command 'rosrun' not found, but can be installed with:
sudo apt install rosbash

If I instead try to run this with ros2 tooling I get this python error:

ros2 run system_fingerprint imprint

I am on 22.04 and if I try to follow the instructions to install rosbash I get this error:

sudo apt install rosbash

If I go to rosindex to find rosbash to see if I should install it some otherway I see that it is part of ros1:

I tried manually installing ros-humble-ros2action, but now when I run it I get an error about missing ros_system_fingerprint. But I can't figure out how to install that module:

ros2 run system_fingerprint imprint

I looked on ros-index and that package doesn't exist: https://index.ros.org/p/system_fingerprint/github-MetroRobots-ros_system_fingerprint/#humble

But maybe it is a module inside this python pacakge?

So the command rosrun system_fingerprint imprint comes from the noetic branch (the default on GitHub). If you switch to the ros2 branch, it says ros2 run system_fingerprint imprint. So the rosbash stuff is not relevant.

The other problems are now addressed in #7. Thanks for testing things out.
