Hi I was following the ros2 doctor tutorial ( and it gave the following warning

/opt/ros/foxy/lib/python3.8/site-packages/ros2doctor/api/ 112: UserWarning: message_filters has been updated to a new version. local: 3.2.4 < required: 3.2.5

My question is, how to I upgrade this package?

I'm a newbie on ROS 2 but probably just using rosdep or with synaptic should do the trick, isn't?

rosdep can mix apt and pip python packages, so things can get confusing.

ros2 maintains its own set python packages in /opt/ros/foxy/lib/python3.8/site-packages. Once you've sourced your ros underlay you can install (or upgrade) a python package with a command like:

sudo pip3 install -t $PYTHONPATH <python package>

If you are on Ubuntu have you tried apt-get update and the apt-get upgrade ? (Use sudo to run as root) (If the ROS repos are on your apt lists , which I am imaign they are for you to get your insstall).
