ROS2/Ubuntu 20.04 rosservice getting "cannot import name 'Log' from 'rosgraph_msgs.msg'"

edit

Hello, I'm trying to run rosservice and getting this error:

$ rosservice 

Traceback (most recent call last):
  File "/usr/bin/rosservice", line 34, in <module>

  File "/usr/lib/python3/dist-packages/rosservice/__init__.py", line 60, in <module>

    from rosgraph_msgs.msg import Log
ImportError: cannot import name 'Log' from 'rosgraph_msgs.msg' (/opt/ros/foxy/lib/python3.8/site-packages/rosgraph_msgs/msg/__init__.py)

Seems all the required packages are installed. What is missing?
